Fish Dying?

[jcat]

I got my first fish a clown on Wed. and he was doing good for a couple days and now he only stays at the top of the tank. All my corals are doing fine and all the water parameters are good. What is wrong?

Jcat,
When I first started my smallest tank, I had a similar problem. For me, I did not have enough oxygen in the tank due to too high a temperature and my skimmer was not adequate. Are you using a filter and a skimmer? Powerhead? What are your water parameters and is your temperature too high? Just some ideas. Good luck!
