i saw some elephant nose fish in the store, says that they were arguably the smartest fish due to their brainsize compared to their body. does anyone have one of these? are they hard to keep? i have a 55 gal with 2 black tetras, 1 painted glass fish, 1 neon tetra( getting more though), a beta, 6 zebras, 2 mollys, 4 platys, 1 dwarf gourmi, 1 small cory cat, and one small bumblebee cat, and a small pleco(not sure what kind) would the elephant fish be compatable in here? thanx guys
