Why did the large fish survive and not the little ones?
< When dealing with goldfish different strains have different resistance to stress.> PLEASE help because I’ve had the remaining fish for 7 years and don’t want to lose him. Is there anything I can do? Will my survivor live on or should I put him down? Is it just shock that is keeping him on the bottom? ANY advice greatly appreciated. Thank you in advance! < Check the ammonia, nitrites and nitrates. The ammonia and nitrites should be zero. If not you have washed away all your good bacteria and may need to re-cycle the tank again. Add Bio-Spira from Marineland to replenish the bacteria you may have washed away. You probably don't have any nitrates since you have changed all the water. Check the pH and the water temp. The pH should be around neutral and the water should be cool (65-70). If you fish is eating then only feed enough food so that all of it is gone in two minutes once each day. If your fish is not eating , then it may have an internal bacterial infection that needs treating wi
