So i bought about 34 goldfish the other day from petsmart. I have multiple ponds and i've already put some in one of them. I have the remainder in a 10 gal (Temp holding) in my room and i put some in my 75 gallon with my 3 year old gold fish. I have 3 out of 21 that have their fins laid down most of the time besides when i feed them. It's been 4 days since ive got them and idk what's going on with them. Their water condition is fine. Most of them are enjoying their new homes swimming around like theirs nothing wrong. It's just these three fish. I've been doing small water changes just to be safe. Has anyone else had this problem?? I do know the nitrogen cycle and my 75 gallon tank is fully cycled. My 10 gallon is not cycled but i do 50% water changes every day. The ten gallon is not permanent as the goldfish will go in my pond friday. Help would be great!!
