All I can say is Wow, as beautiful as it looks it is also so sad, but the clarity of the water and the plants and fish look so beautiful, just like an aquarium, I would of never expected something like this in Austria.
At around 9:54 he mentioned that scientists state that the tropical fish don't disturb the local ecosystem because the creek is small and connects directly to a cold water stream, where the non-native fish can't survive. The only concern is the US-native crayfish because they're more tolerant of colder temperatures.
@@Constantine_Cvl8Dont forget lepomis. Any American will tell you that those things will thrive just about anywhere. They are aggressive as cichlids are, and guard their fry too. Extremely colorful during the summer though
The Red Jewel Cichlids are in the genus Rubricatochromis these days Chris, and the shown species is most likely R.guttatus, the most common one of this genus in the trade, mostly uncorrectly named R.bimaculatus. The Pseudotropheus is still sp.acei, still not officially described as far as i know.
Thank you for the very interesting video about tropical cichlids (and not only) that have perfectly adapted to life in this stream fed by underground thermal springs. The list of tropical fish and plants is incredible!
Probaby one of thr most concerning species there are the sunfish. Sunfish are bulletproof. Lots of species look as colorful as african cichlids in breeding season though. Awesome fish to keep.
The creek is beautiful. Being from the US seeing non native fish in areas they dont belong in is sometimes concerning but i also understand thatnif the non natives are not affecting the local populations of wild life how they can be enjoyed as just part of the current ecosystem
Ancistrus dolichopterus is currently considered the proper name of a different species, and the common bristlenose is usually referred to as Ancistrus cf. cirrhosus. While I'm not an expert on Cryptocoryne, I do know many of the species have multiple strains some with very different looks, and even within strains looks can vary greatly with living conditions. It doesn't look like any strain of C. usteriana I know of, at least as they looked in the conditions I've seen them in, but then again, my knowledge is limited. Personally I'm not so worried about a few tropical fish in micro habitats in temperate regions. Not that I think it can't be problematic, just that it's kind of insignificant compared to what we transport in other ways, intentionally and unintentionally by travelling and transporting goods. It can be surprisingly difficult introduce a new species to functional, well developed ecosystems. Just the lack of co-evolved competition, predators and pathogens/parasites doesn't make an introduced species invincible, the fact that an introduced species hasn't co-evolved with all those threats in the new ecosystem is probably usually much bigger disadvantage than the freedom from co-evolved "problems" are, assuming a reasonably well functioning ecosystem. Except for diseases, some parasites that and probably a few other exceptions, like some predators maybe. Another specific situation is when the introduced species carries some disease that doesn't affect it as much as it affects the competition in the new habitat. While I'm not encouraging release of fish, neither from other continents, or even from other waters in the same country, without a proper understanding of the potential consequences, including potential spread of pathogens and parasites, it would be interesting to know if some wisely chosen predators could be used suppress specific species more than others, or even eradicate some species, ideally without eradicating non target species. If done scientifically, by actual scientists, that might produce useful knowledge. Prime targets for such research to control should probably be the species that can survive outside that micro habitat. In the case of the crayfish I think it would be interesting to find out how much effort it would take to eradicate it completely, using any reasonably safe and uncontroversial method, including using traps.
sprenger 's iodotropheus Iodotropheus sprengerae is clearly visible in the video several times, you forgot to mention it in the list at the end of the video!
I believe - problem WAS, when those fishes was released. In so unique place, before those invasive spieces was released - possibly lived some rare and unique local community of animals. And they already is gone. Another problem - tropical bacteria and diseases.
Interesting that there are gudgeons in the creek. They should not be kept at temperatures >22°C they say. Otherwise very cool, even though I think one should be cautious with New World species, especially from North America and Southern South America.
I can't believe people are still dumping fish into the environment... Thankfully most of them can't spread too far but it's still sad to see the educational gap in society about invasive species.

you guys are super strict when it comes to this..

@@chrislukhaup Yes I guess, but only because we have seen first hand what damage can be done with feral species,.

Thanks for sharing this beautiful
Incredible, thanks for sharing
Absolutely fantastic video tour 🙌 👌 ❤
Amazing share. Tks a lot!

Great video Chris 👍 thanks for it
Thanx Oli..next time together
I enjoy this so much! Amazing content, best wishes to you and your future projects! 🌻
This was epic! Man the colors on these fish were stunning, even the convicts had very vivid coloration!💯🤙🏼
Wow 🤩 So nice creek and video 😉
Marc
Very cool! Never thought I would’ve seen those fish there! Thanks for sharing!

true because they can survive the colder water too.
Thanks for sharing! This is awesome!

lol the Hongi was begging you to take him home, he realized aquarium life was easier =D
Thanks Chris, great video!
Amazing, planning on trip next year all being well, i will gladly visit this place, thank you for sharing
Wow that's so cool 👌 beautiful fish 🐟🐠
If I'm not mistaken Pseudotropheus sp. Acei is now referred to as P. elegans
Great video
BEAUTIFULL :)
THANK YOU FOR SHARING :)
THANK YOU FROM ISRAEL :)
Loved your video!
thanx !
Amazing ❤

i thought it is L.hongi
Wow

Interesting, thanks for sharing. Where exactly is this? Name of the place or GPS?
Someone’s gotta put a big colony of zebra plecos or something expensive like that in there
5:30 cryptocorine growing in the background? The yellow tail acei looks amazing!!! Their colors are beyond any I have seen in aquariums.
I suppose it have to do with the minerals of the spring water?
How are these tropical species surviving in Austria?
thermal..
Great video.
I can't believe people throw fish in ponds to "get rid" of them, give them back to the fish store?
i like aquarium fishis in ponds :3
😊😊😊like😊😊😊
Pseudotropues aceii yellowtail
👀
I can't believe people are still dumping fish into the environment...
Thankfully most of them can't spread too far but it's still sad to see the educational gap in society about invasive species.
its fine they look better than native also they cant spread. except for the crayfish causing shits
Vallisneria Gigantea...not Spiralis.
What an amazing adventure! Thank you for sharing. 👍
Thank you. What a treat. Hi from Australia
