Joey, perhaps the smaller one are the almost same, but different species the, Caribe Piranha? Caribe Red Bellied Piranhas are more aggressive than normal red bellied!
The smaller ones are all about survival mode, so they need to be more aggressive and bold. The older ones kind of have a sense of "ok, we are safe and fed so" Genetics can play a part of course. I wanted to add in, the size of your aquarium plays a HUGE part as to why these tetras are ignored. A lot of people want to have "tank mates" with their piranha in their standard size aquarium and that's a recipe for disaster. Public aquariums, for example have leporinus, cichlids, other piranha species and "works" because of tank size.
My 20 gallon tank is infested with assassin snails! I had a snail problem so I added 5 and now I have like 50 or more. I exchanged one snail problem for another. I don't think that'll fix the problem. They are cooler looking though. Love the tank, the red on the piranha looks great a camera. Also I think that small green plant shooting runners is dwarf sage not a crypt. Thanks Joey!
Joey, how about a mobile sand lift, like the sand waterfall, where the sand falls through the sifter and catch the snails. Just vacuum the sand once a day instead of digging in it.
I can not wait to see you breed them as you have some that are mature enough(at least one egg laden female). Lots of secrets to unravel in that process! You are the guy to show us! Breed them please! Kev
Snails. I stupidly and intentionally added a few little snails in to my tank. Thought it would be a nice edition. Dididnt think it would get to bad. Well it did and they just exploded and got in to everything, even the filters. And I did so much water changes and cleaning and spot killing-nothing seemed to work. I got one little clown loach. One. That little dynamo single handedly ate thru a 30 gall worth of snail infestation in just a few days! Bless that little hard worker, it was amazing to see the little buggers disappear nearly overnight. Moved him in to my 20 to clean that up too after he was done with the 30. I'll never forget that tiny terror of snails. If I ever start up a tank again, im getting another for sure.
Not to say you're wrong but in my 125 I have only 3 red belly piranha, 5 inchers and they ate all of the tiger barbs that I introduced into the tank, the same time as them. Anything I try to put in there as a tankmate dies (instant food!). So no more, not looking to sacrifice any more poor fish. And yes I feed them plenty but it still doesn't matter.
Hello sir.. just a fellow hobbyist and a follower of yours here.. my opinion is your pirana tank is actually look dark you can bring the lights a little down or anything you figure would be good..
Tank looks great. I’d say be patient first. When I had them before every time I change aquascape they where shy. I didn’t change it often most by accident fixing or adjusting plants. Overtime they came back out
I saw the bleeding heart tetra in a number of videos. I didn't realise you hadn't told people. They and purple emperors were my favourite tetras but there's many others that are beautiful. I think red belly piranha are typically carrion feeders, unless they're really hungry. So, so long as their fed they shouldn't go after the quick little ones, as they're too much effort. Puffers are Amazonian so might get rid of the snails but then, they're slow and some might get picked off by hungry piranha.
I'd say the smaller ones aggression is down to feed drive and the need to grow fast, suppose we'll know when they are all of Equal maturity, if they still hold the same level of aggression.
Yeah, a lot of carnivorous fish, even axolotls, are way more aggressive until they reach full maturity. I always put it down to their higher need for food while they're growing.
I enjoy watching your videos. I have you DYI book, which is a value book in my aquarium collection. Thank you for sharing! Petrified Wood will never stain your water. It has the wood grain look, but it turned to stone. Puffer fish will devour your snails.
Yes, Assassin snails are a good choice; mind you that assassin snails can be a pest too. They just don't breed as quickly and they are much better looking, specially with that black and yrllow combination. In my experience, If there are no more snails to eat, they will also eat leftovers like the common pest snails.
I used to have 150 gallon planted fish tank with 10 piranhas and it they grew to close to a foot in size I had jacked Dempsey's convex breeding in the tank schools of 300 fish Dempsey's in convicts with the piranhas... I believe why you're smaller piranhas are more aggressive is because they are younger and more active the older ones tend to get more mellower as they grow older.. I really enjoyed watching your video and tempted to do another piranha... tank but.. I have 180 gallon community fish tank now with ram cichlids also have balloon rims electric blues and assorted of other fish that I would like to try to breed with angelfish..
my advice to you is that dont add assassin snails because you will have problems with them, they will also produce a lot . i add Helena snails to resolve my problem, add 3 to my 30G tank,after couple mounts they kill all other snails but they produce a lot, now over 40 of them i have 😅😅😅
Which just gave me idea if you did make it an living micro ecosystem you could pair that with aquaponics aka letting plants filter the water for your fish and the fish to feed the plant so the plants would benefit from any biowaste from the fish if you did go that route
Fishing with potatoes was working but you might not have taken it far enough. Try a 5 lb bag each night for a week and problem should be over. Overfishing principal works at every level.
So I have decided to attempt a 60-gallon sealed barrel version of your 5-gallon canister model. It is for a 120-gallon tank with your "office build internal sump" for a serrasalmus elongatus; they love a strong current, with a Freesea wave maker, FS-230 at other end. Sump is overkill, but it will help with surface debris, and I built it there before I decided not to use the FX6.
Love my assassin snails. They will breed in that tank too so you’ll end up with just the right number to keep the nuisance snails in check. Balanced ecosystem. No more snail hunting which used to be my least favorite maintenance task. Think a polishing pad in the filter would fix the clarity really fast too.
Years ago when i bought new plants and they were fulk of snails,i tried putting them in a cup of water with a spoon of aquarium salt.All the snails were dead on the bottom but that killed the plants as well.Perhaps cause too much salt is not good or because i waited for 30 mins.Maybe less time would do the trick and then with some water changes it would be ok?...
Hi Joey. Just a note from my experience of adding assassin snails. My assassins started breeding and then I had an assassin overpopulation problem. Good luck 🙂
I think that assassin snails might work better than you think. Then, once they're done, remove and rehome? I took care of a serious infestation of a 350 gallon tank with 75 assassins. 20L took 5 and a week.
I was thinking that was dwarf sagitarria also. I'd definitely let it fill in though, that would look awesome! Maybe add a few pots along the front to speed up the process.
Snails are the reason I don't have beautiful plants. To get rid of the snails,I emptied my tank, I threw everything out of it. I could do it, as it was only a 10g. Threw out the plants, emptied the tank. Started over with a different tank. Snails heavy bio load was un manageable to me. I advertised free snails. 3 times I took a load of them to the pet shop, a 3hr round trip. I just couldn't keep doing it. Tossed everything.
Breeding possibly happening but need to do a lot more water changes more frequently and cooler water with more food and breeding will start..also add some salt since it connects to the ocean, i used to breed. Piranhas.... But your Joey you got his man....hope the best
Joey try dumping a bunch of 2lt plastic bottles in with lettuce do a bunch all at the same time tie string to the end fill with the tank water and sink them to the bottom the snail love it. And easy to remove obviously no lid. U will catch 1000s in a cpl days mate 🤙🇦🇺🙏❤️
Please keep the piranha videos coming! You have the best one out there outside of maybe a zoo. Plus you have plenty of good advice and ideas that inspire me to make the best of what I currently have for my 4 juvenile piranhas. I only have a 75 gallon tank and even having 4 is pushing the limits. It’s too bad because I would love to have a 700 gallon tank with 30+ red bellied piranhas. Their behavior is intriguing and the more you have the more they behave like they would in the wild . I think you should go with your gut and allow those plants to branch out and grow. In 6 months, like you said you will have a nice carpet of green going back to even taller plants. I use an undergravel filter plus two Seachem Tidal 110’s on my 75 gallon. I know undergravel filters are old school and probably a joke to most but back when I got a 55 gallon tank back in 1985 for my one piranha it proved to work perfectly maintaining good water quality. I did though also have a hang on back filter too. Not sure though what brand. I think maybe it was an AquaClear. Thanks again for the entertaining and informative videos!
So long Island aquarium had them with red bellied piranha in a 2000g if I remember right. My guess is that it is possible with large and well fed piranha. I don't see why cardinals will have a problem.
All my sand snails died when I treated my aquariums with Fenbendazole to get rid of planaria. No fish or shrimp loss and my rabbit snails and ramshorn snails had no problem surviving.
Hey Joey Cant you get snail eating snails in Canada. Take a Look for for anentome Helena. The best way an very cheap at least in Germany. Hope you'll get them in your Area .
Ciao king sono italiano complimenti x i video li sto guardando tutti. Volevo chiederti che luci usi nella vasca piranha ? Se usi led a che percentuale usi il rosso il verde il blu e il bianco ? Spero mi risponderai grazie e complimenti
I have those brown crypts in my tank and the same ones in green and they also make runners like crazy. So it isn't just the small crypts that might spread in your tank
Thinking small ones next to feed more often bc they are growing at a higher rate and burn more energy doing so? Larger adults can take bigger chunks but dont need as much food? Similar to snakes where younger snakes need to be fed more often and adults less often but have bigger meals?
The only piranha i wanted my lfs had one. It was a black piranha. From tail to bear trap it had to have been almost 2ft. Just amazing even just looking at him.
Simple solution to your snail problem put a slice of banana on a shish kabob and Jab it into your sand give it 45 hours then remove it slowly it'll be full of snails
Piranha would be cool if they stayed around five to six inches, every time I had them they got huge and just hid behind the decor in the tank. Most people have a big tank of maybe 75-100 gallons and only maybe four or five usually survive in that size tank, that’s why I think it would be cool if they stayed around six inches in size. How many do you plan on keeping in that tank when they get fully grown?
I temporarily added my oscars to a planted tank that had a similar snail infestation and the oscars ended up killing every single one of the snails. I don't know if oscars can be added with piranhas but maybe that will work.
Im alredy scared of my 3 glofish how you think ill feel sbout these if i get them? my glofish did try to bite my finger with its lips and no teeth So not sure how ill feel about piranha
I prob imagine genetics are involved with Aggressive behaviour 🤷♂️, I mean that how it often works with other animals, dogs are a great example, but any animal will typically have some variations in behaviours then the behaviours that are best suited to that environment will end up outbreeding the others and it will evolve to become more that way over a few generations, sometimes it can fluctuate also depending on time and environmental changes
Watch all the feeding videos: ua-cam.com/video/LO76IoYOAg0/v-deo.html
Joey, perhaps the smaller one are the almost same, but different species the, Caribe Piranha?
Caribe Red Bellied Piranhas are more aggressive than normal red bellied!
The smaller ones are all about survival mode, so they need to be more aggressive and bold. The older ones kind of have a sense of "ok, we are safe and fed so" Genetics can play a part of course.
I wanted to add in, the size of your aquarium plays a HUGE part as to why these tetras are ignored. A lot of people want to have "tank mates" with their piranha in their standard size aquarium and that's a recipe for disaster. Public aquariums, for example have leporinus, cichlids, other piranha species and "works" because of tank size.
What about an army of pea puffers, small enough where the piranha won't eat, and they love to eat snails.
When I had pea puffers they didn't eat the sand snails only my ramshorn snails.
Possible probably but more expensive than most tetras as well.
My 20 gallon tank is infested with assassin snails! I had a snail problem so I added 5 and now I have like 50 or more. I exchanged one snail problem for another. I don't think that'll fix the problem. They are cooler looking though. Love the tank, the red on the piranha looks great a camera. Also I think that small green plant shooting runners is dwarf sage not a crypt. Thanks Joey!
Wait, what are the assassin snails eating when they totally eradicated the other snails?
Joey, how about a mobile sand lift, like the sand waterfall, where the sand falls through the sifter and catch the snails. Just vacuum the sand once a day instead of digging in it.
14:12 "those are snail trails" 😂😂
HAhaha Tamara's reaction in the reflection when you say that "Maybe I should do this all night.."
Caught that too 😂
10:05 I think it will be nice to watch the plants take over the tank!
Almost 2 years of not watching he's videos.. just watching to inspire me more to go back in keeping fish 😌🥰
I can't believe how lush the tank is. I watched you plant it and its grown phenomenal. Great video as always 👍👍🇬🇧
I can not wait to see you breed them as you have some that are mature enough(at least one egg laden female). Lots of secrets to unravel in that process! You are the guy to show us! Breed them please! Kev
Hello, thank you for the nice video about piranhas and the method of disposing of snails, but most importantly, that you played the subtitles.
Snails. I stupidly and intentionally added a few little snails in to my tank. Thought it would be a nice edition. Dididnt think it would get to bad.

I kept piranha for many years and I would point out that if you don't feed them for a couple of weeks all those tetra will disappear.
Hello sir.. just a fellow hobbyist and a follower of yours here.. my opinion is your pirana tank is actually look dark you can bring the lights a little down or anything you figure would be good..

Puffers are Amazonian so might get rid of the snails but then, they're slow and some might get picked off by hungry piranha.
I think your cloudiness is caused by heterotrophic bacteria. More water movement and surface skimming plus UV should clear things up.
I'd say the smaller ones aggression is down to feed drive and the need to grow fast, suppose we'll know when they are all of Equal maturity, if they still hold the same level of aggression.
Yeah, a lot of carnivorous fish, even axolotls, are way more aggressive until they reach full maturity. I always put it down to their higher need for food while they're growing.

I love all your videos it's my favorite time of the week.. Thank you for all your knowledge and for just being you lol
You really love your piranhas. I would love to see the sea horses, the octopus, the discus, the goldfish progress, the archers... Everyone you know?
This piranha tank is the dream of every supervillain.

Thanks for sharing Joey you are the best and this tank is pure inspiration
You can use a pleco for the snail problem. I got malaysian trumpet snails and keep the pleco without food and he wipes out the snails.
Dude! It's a great tank! Just add Surface Skimming!!! and and a few more wave makers, and a UV sterilizer. Get that water crispy!
Years ago when i bought new plants and they were fulk of snails,i tried putting them in a cup of water with a spoon of aquarium salt.All the snails were dead on the bottom but that killed the plants as well.Perhaps cause too much salt is not good or because i waited for 30 mins.Maybe less time would do the trick and then with some water changes it would be ok?...
We’re did you the tree trunks for your tank
Hi Joey.

I think that assassin snails might work better than you think. Then, once they're done, remove and rehome? I took care of a serious infestation of a 350 gallon tank with 75 assassins. 20L took 5 and a week.
You need to put better lights on tank looks dark
I was thinking that was dwarf sagitarria also. I'd definitely let it fill in though, that would look awesome! Maybe add a few pots along the front to speed up the process.
Not crypt larva. That’s dwarf sagataria.
Looks like it a little bit, but no, it simply isn't. These came from labeled and sealed tissue cultures.
Hey man I have lots of questions for you I have 7 rdps wanting to know how you got ur wood set up so great!!
Snails are the reason I don't have beautiful plants. To get rid of the snails,I emptied my tank, I threw everything out of it. I could do it, as it was only a 10g. Threw out the plants, emptied the tank. Started over with a different tank. Snails heavy bio load was un manageable to me. I advertised free snails. 3 times I took a load of them to the pet shop, a 3hr round trip. I just couldn't keep doing it. Tossed everything.
The Crypt Wendtii will tunnel and spread as well. My 75 had a carpet of it once it got going.
Fascinating! Never knew a fish video could be so interesting! ♥️
We used to diatom murky tanks back in the day. Those fishie at 6" will be scary! Had a black one years back more pointy nose.
Breeding possibly happening but need to do a lot more water changes more frequently and cooler water with more food and breeding will start..also add some salt since it connects to the ocean, i used to breed. Piranhas.... But your Joey you got his man....hope the best

Had piranhas long ago, to this day my favourite freshwater fish, really beautiful tank!
I'd like to see what equipment you use as far a filters and your cleaning routine for such a big tank..
Please keep the piranha videos coming! You have the best one out there outside of maybe a zoo. Plus you have plenty of good advice and ideas that inspire me to make the best of what I currently have for my 4 juvenile piranhas.

Stayed up just to watch this.. commitment to the cause 🇬🇧
Just wait till a pair start to breed the nest building and territory fights
I can't wait to get my tank and stand set up... I've learned a lot from you 🥰😍
Could you keep Cardinal Tetras with the Piranha? Or is it best to have less brightly coloured tetras?
So long Island aquarium had them with red bellied piranha in a 2000g if I remember right. My guess is that it is possible with large and well fed piranha. I don't see why cardinals will have a problem.
@@zafishguy5166 Oh perfect, thank you, that would be my dream tank if I ever have the space
My dad had 4 piranhas and the smallest was the most aggressive and eventually turned out to become the biggest in the end
Speaking from experience, if you use assassin snails to combat a snail infestation you may just end up with an assassin snail infestation
Have you tried making snail traps?
All my sand snails died when I treated my aquariums with Fenbendazole to get rid of planaria. No fish or shrimp loss and my rabbit snails and ramshorn snails had no problem surviving.
Hey Joey
Cant you get snail eating snails in Canada.
Take a Look for for anentome Helena.
The best way an very cheap at least in Germany.
Hope you'll get them in your Area .
Love your tanks, love your work, and you’re the man.
This has been my favorite tank since you started it. Definitely still true!
Ciao king sono italiano complimenti x i video li sto guardando tutti. Volevo chiederti che luci usi nella vasca piranha ? Se usi led a che percentuale usi il rosso il verde il blu e il bianco ? Spero mi risponderai grazie e complimenti

Are they Caribe red belly ? If so they are meaner compared to the regular red belly
They are all red bellies
Caping it with seachem fluorite sand would work great and still be good for the plants
Love your content and fish tanks👌💕 Let's add a Snakehead for the Gallery 😁 ❤️ From Sri Lanka 🇱🇰
I had a snail infestation years ago. I was able to get rid of them easily just dosing the tank with API's algaefix a few times.
Build yourself a snail trap. Easy and does the job in no time.
It’s like a 5 year old and a 30 year old, the 4-5” juveniles are like kids and have more fiesta energy.
Have you ever considered the Exodon Paradoxus as a dither fish for this tank? Great and very active (Aggressive) dither fish for a Piranha Tank.
What about Pea puffers for the the tank.
That’s what I was thinking. Would eat the baby snails in the plants and on the wood
And maybe to small for the piranhas to eat.
Simple solution to your snail problem put a slice of banana on a shish kabob and Jab it into your sand give it 45 hours then remove it slowly it'll be full of snails
Use a siv and siv your sand. The small grains of sand will fall through and the snails will collect
You'll probably need more lights in order for those plants to grow the way you want it to towards the front of the tank.
Its me FISH GUY RANCH nice video buddy
Nice tank! May I ask what kind of wood you are using? Looks great!
Make a snail trap put like maybe an algae wafer in and scoop all the snails you catch
You need some more water movement in that tank.
Piranha would be cool if they stayed around five to six inches, every time I had them they got huge and just hid behind the decor in the tank. Most people have a big tank of maybe 75-100 gallons and only maybe four or five usually survive in that size tank, that’s why I think it would be cool if they stayed around six inches in size. How many do you plan on keeping in that tank when they get fully grown?
I think they truly need a tank over 180 and large groups to be kept properly. The other option are those large piranha that can be kept as singles.
I temporarily added my oscars to a planted tank that had a similar snail infestation and the oscars ended up killing every single one of the snails.
I don't know if oscars can be added with piranhas but maybe that will work.
Thanks King !! Love the videos
Question: What fish can’t swim? Answer: A dead one.
@Thekingofdiy what’s the name of the plants in your Fish tank Again
you can get freshwater crabs that eat snails.
I had the same problem when I had 30 baby umbee, the smaller ones would attach and kill the bigger ones, maybe I should do a UA-cam video on it.
21:37 xDDDDDDDDD
Im alredy scared of my 3 glofish how you think ill feel sbout these if i get them?
my glofish did try to bite my finger with its lips and no teeth
So not sure how ill feel about piranha
Helena snail FTW in getting rid of other snails
I prob imagine genetics are involved with Aggressive behaviour 🤷♂️, I mean that how it often works with other animals, dogs are a great example, but any animal will typically have some variations in behaviours then the behaviours that are best suited to that environment will end up outbreeding the others and it will evolve to become more that way over a few generations, sometimes it can fluctuate also depending on time and environmental changes
I almost feel like you could use this tank to breed assassin snails if you really wanted to
I use Fritz Monster 360 in my tank and I believe its whats making my piranha tank water cloudy !
Looks great!
What about puffers? Like Amazon puffers to eat the snails? You think the piranha would mess with them?
Beautiful tank
