If these fish didn't become my favorite bottom dwelling fish of all time, i would certainly choose something else. Cause these fish can scare the crap out of you sometimes!! Problem with these guys, at times one will be on his side in the corner of the tank (away from all the others)..just like when u find them bellyup..they can be just so convincingly dead at times, till you knock on the glass in shear panic..so worth the stress though!!
