Possible Ich

[FireWater]

Test again. When you moved the rocks you might have stirred up enough stuff to throw your levels out of whack. It sounds as if the fish are stressed out from something in the water. The ich is an after effect. Water change now to be safe. Try to feed lightly but often. It will have to run its course..

I bought everything new but that's a good idea and I'm definitely going to check. Thanks.

New? How long has it been set up?

[Umiamifan]

It's been up for about eight months.

I didn't see any signs. The yellow tang was sudden....was eating and then a few hours later was dead. I came home from work today to find my angel dead. I noticed the spots on the blue tang as he was swimming and turned up towards the light.

Just in case, get some new food too. Any pics of the tank display and sump?

I'm having trouble posting pictures of my tank.

I think I posted two pics on my profile.

Thanks. Still a work in progress. This situation will slow it down though. I want to thank everyone for all the info.
