So a question for anyone who raises gold fish. Do you have A/C in your house where you keep the gold fish? If not, how do you keep them cool? I know they can withstand cold water temps since I have ones outside in a pool, and can live in deep ponds that are frozen for winter, but from past experience, they couldn't take the heat. Ponds are outside, but I know that a large in ground pond isn't going to reach 80F if the air temp is 90F, unlike a fish tank in a house which is a much smaller volume. I had gold fish who lived pretty well between 65-75F due to A/C in the house....then the A/C broke for a few weeks and all the fish died, despite extra water flow in the tanks in attempts to increase dissolved oxygen content. Day highs of 90-95 seemed to just not go with them and they all eventually got sick or something and jumped out of the tank... in under two weeks. I was maybe 14 at the time so I don't remember details so well. I now have other gold fish that have lived many years in the temp controlled house and are anywhere between 6-10 inches long now so are doing rather well. Do I risk moving them to a non air conditioned living establishment? Reason I ask is because I wonder if what I had experienced in the past was a fluke, or if they really just can't stand the heat. Thanks!
