Re: dying fish We have live rock. Got rid of the bio balls. We are using a skimmer. Water changes monthly or when needed. Using reverse osmosis water. We have one chromis left that seems to be going blind. No visible disease or discoloration of eyes. Decrease in eating. Other things in the tank are two condies, a cleaner shrimp, a mandarin goby, 5 blue crabs, 5 turbo snails, and a chocolate chip starfish. |
