hi everyone. this morning i purchased 3 small goldfish from petsmart for my 180 gallon tank, currently filled with 7 adult goldfish. i recently noticed that one of the fish's fin is blackened at the tip.
should i worry about this?
water paramaters are 0-am, 0-nitrite, ph-7.7, and unknown nitrate.
oh, and all the fish are swimming at bottom 12 inches of the tank. is that bad? or are they just shy?
