What troglophiles are found in captivity? I am referring to species (terrestrial or aquatic) that live their entire lives in caves - so not bats. I know that Blind Cave Tetras are pretty common in captivity (I even keep this species ). Texas Cave Salamaders are kept by a few US zoos, and I know a collection in Texas keep Mexican Cave Catfish. I know at least one US zoo keeps Shocking Pink Dragon Millipedes. And doesn't a Japanese collection (Ueno maybe?) keep Cave Glowworm? Do any collections keep Cave Angelfish? Anything I didn't mention?
There's Olm, of course - held at a pair of collections in their native range, and a single collection in Japan.
