the tank is about 70 degrees. I did move them to a new tank ( a larger one) after the first few days the shubunkin arrived. maybe he is acting strangely because of the new tank?
I recently got a shubunkin goldfish. he is currently in a tank with 2 other regualr goldfish. He was fine for the first few days. He now seems more lethargic than the others and will often just hang out at the top of the tank and not swim or move around. The other two fish are fine and swimming...
