he sometimes "lays" on the bottom of the tank like hes sleeping.. or dying. i tap the tank and he "wakes up" and swims away. he has a nice hiding spot... a black PVC pipe he usally stays in there when lights are on. but, lately hes been out and about .. but doing this "laying on bottom of tank" type of deal. shrug. is he going to die? i got him from the same pet store that sold me the 2 mollies and 2 angels that died.. which, 1 molly and 1 angelfish is still living. shrug. advice pls.
