A while back I posted a thread that asked why some species of birds seemingly easy to keep are not often kept. Today I want to make an antithesis thread that discusses commonly kept animals (or at least seen at, say, every other zoo or aquarium) that you think don't do well in captivity.
This thread is to discuss specific species or just groups of animals somewhat commonly kept that just, in your opinion, don't do well in a captive environment. If you have seen examples that stand out where your species actually does well, please describe it!
For me, it's salmonids. I have never seen a salmonid in captivity (a fully-grown salmonid, fry seem fine) that looks decent. They all seem very pale, are often very slow-moving in comparison to wild animals, and just...they don't look right to me. I'm also not sure if they live that long.
