Great video! Just found your channel thanks to the algorithm :) Very interesting to hear your experiences with both species! Do you think these species tend to ignore smaller fish? I notice you keep much larger species of fish than I normally do. I've had a rainbow shark for 8 years now since he was ~1.5" long and always kept him with smaller community fish like danios, barbs, tetras, corydoras, dwarf cichlids, livebearers etc, plus some closer to his size like a BN pleco and blue gourami. I've moved him to several aquariums and he's always shown the same pattern with no real aggression, even when introducing new fish. He will claim a cave/rock/log as his territory and sometimes shoo away other fish that stray within 6 inches or so but is otherwise totally passive, he roams and ignores other fish and doesn't fight anyone at feeding time either. Am I just insanely lucky or are they hard-wired to target fish their own size or larger?
You’re pretty lucky. In my experience, they usually don’t discriminate and will go after larger fish, fish their size, and small fish. I’ve had some rainbow sharks and redtail sharks that would chase bala sharks that were 3 times their size, and some that would chase tetras and tiger barbs all over the place. I occasionally see the one I have now chase my rainbowfish and serpae tetras, all of which are smaller than him, but he mostly chases my roseline sharks and Siamese algae eaters. Most of the roselines are bigger than him, some are smaller, and the Siamese algae eaters are the same size as him
I used to have a redtail shark that was really laid back, barely ever chased any fish, one day he passed away out of the blue at 6 years of age, I have been considering getting another one but I fear that I might not be so lucky when it comes to temperament for a second time.
These fish are fast. They can swim really fast. Faster then most other body types. What I did was add "agile" fish. Fish that can out swim a red tailed shark. I used yoyo and zebra loaches. Their ability to turn faster leaves the aggression with no target. Fish like rainbows and gourami tend to be the opposite of this effect in that their large sides and slow turns leaven them vulnerable to the sharks speed.

Yea it would be risky. They all have different personalities
Looking good. Hope the decision leads to better things and the shark to survive the shipment.
When I had my red tail, which was one of my favorites, they were right up in the loaches faces. However the loaches were up to that challenge!
