I'll tell you what I've found out so far, but I've never quite been up to acquiring a pair. They're just sort of an ongoing interest. Tentacles are completly aquatic. They have reduced belly scales and can't really crawl well on land. I'd imagine they dry up pretty quick too. They prefer warm (80-85) water and a low pH (6.5). I never quite found out what sort of salinity they like. Good water quality is also important. They like a lot of plant cover and eat live fish. I guess they stiffen up like a board when held, and are slow strikers, but if I were you I'd try to avoid getting bitten. They're good escape artists and a major reason I don't have any is I couldn't figure out how to fit a filter and heater on the cage and still make the lid escape proof. Also, i guess the algae growing on their skin is important and they are very vulnerable when they shed. They're live bearers.
