ok i got some knight gobby's a little while ago and just upgraded the tank that they were in from a 20 gal tall to a 55 gal and i'm noticing now they are always up at the top of the tank either laying on plants or ontop of my undergravel air pumps is this normal? i only ask because in the old tank they used to hide in the caves and stayed near the bottem of the tank now they are up at the top is it normal?? and i know my water levels are perfect as i test them every 3 days. or could it be i have to much current in the tank for them? cause i have my undergravel filter and 2 over top filters 1 on each end of the tank... help me figure this out please pelase please!!!
