softer water... somewhat larger fish so they need a larger tank... pretty blind and slightly electric, they use a type of "sonar" to "see".... only one electric fish per tank, this includes elephant noses, glass knives, BGK and a couple others i can't think of atm. pretty fish, very docile, could be easily harassed by almost any other fish. predatory, so anything smaller could become a meal. scaleless fish basically, any treatments will have to be carefully given.... eats bloodworms and maybe shrimp pellets and maybe ghost shrimp... and like i said, any other little fish that will fit in its mouth.......
specific questions just ask........ this is sort of a wide answer and i didn't want to write a whole book.
