Well, apparently I'm not very good at keeping fish alive...:mad2: I came home from work today to see my sailfin tang I've had since November along with my new powder brown which I got Wednesday afternoon both dead. They are in two different tanks and I checked the water in both after I got the fish out. Water checks out fine in both tanks 0,<0.5,8.3,79.5 in the 135 and 0,<0.5,8.2,78.5 on the 55gal. I know I saw a post before about a coral only tank, I'm starting to think I should do that. I've spent way too much money on fish and I haven't really bought anything expensive. The powder brown was the first one over $35. Anyone have any suggestions? The thing that really confuses me is the other fish in both tanks seem healthy and happy and the little bit of coral I have in the 135 seems very happy.
