Everytime I turn on my aquarium light, my fish will go to the bottom of the tank and hide. They won't swim unless its turned off even when they have time to adjust. Is this normal? The light is 14watts.
I saw a dwarf fuzzy lionfish at Petco recently! I've been wanting one of these but I already have two percula clowns in a 20 gallon nano tank. Would the lionfish fit?
I got a domino damsel since I heard it was a hardy fish and it looked cute but then I saw their adult pictures and AH they are nasty looking! so don't get them. Does anyone know any successful tankmates?
