Hi, I've been reading this forum for a while and just decided to reply to a post. I had an elephant nose. They are difficult at best. They only eat live food. They are shy and need a tube to hide in. Oh and did I say that they are nearly blind. They cannot compete with other fish for food. You will have to always have a supply of live bloodworms handy. If other faster fish are in the tank with them the elephant nose will slowly starve to death. They emit an electric pulse that seems to aggrevate the other fish in the tank, though it's not strong enough to hurt the other fish.
These really are great fish, but you have to dedicate an entire tank to them alone.
