I have only goldfish in my pond. I went to Petsmart today to poke around. Looking at the goldfish, possibly thinking of buying some nicley colored ones. The three tanks they had contained a fair number of dead fish. Is this normal or is it something I should be concerned with? I have never seen that many dead ones in Petsmart before maybe 1 or 2 per tank. Do you think I just came a time when they had not yet culled out the dead ones? I didn't buy any as I did not want to chance transmitting a disease to mey pond. I really didn't need anymore, just looking for oddly colored ones.
