it would probably be similar to my toadfish which is brackish, never moves and has a cavernous mouth!!! I made the mistake of putting quite a large puffer in with my toadfish to add some activity to the tank and it wasn;t there in the morning. My mistake for being an idiot but these kind of fish are nice to have but they don;t make for a display tank as they don;t do anything

i've got a Hydrocynus vitattus in one of my tanks, they are pansy fish that are scared of their own shaddows.
