i went last night to a guys house thats moving and bought about 80 lbs of lr from him $200. well i bought it in my 20 gallon fowlr. the fish in there are 2 percula clown fish. this morning i got up to turn there light on and they were in a corner at the bottom still halfway sleeping i think...so i went back in there like 2 hours later. and they were still doing it. i fed them, then they just went right back down to the bottom and swam in place. is there something wrong in the rock or do you think they are just getting use to all that rock in there tank. and they also look fine. and i also didnt put all of that rock in my tank by the way. tia
