well anything is posibol but there is a problum it has a short life span and only eats jelly fish plus if i rember right it is a deep water so the tank would have to be presherized big money lol
It's not deepwater in nature. Can't be since it feed on nematocysts from floating man-o-war jelies. However, aside from eating nematocysts, it incorporates the jellies stinging cells in the surface of its own skin as a protection against predators.
