Fish stopped eating

[chrislPa]

O.k. yesterday morning when I fed mysis one of my anthias and my clown didn't eat. Last night same thing but the clown did eat a small bit of flake but the anthia, nothing. This morning fed the tank now the other anthia isn't eating either. So really the only fish that is eating is the yellow tang. I don't see any signs of any disease. I treated for flukes about a month ago and haven't seen any since. Please help!

Without other symptoms, I wouldn't panic. Fish often will not eat for a day or two and then start eating again with no problems. The first thing that I would do is check for non-disease causes. Has your routine changed? Are all your parameters steady? Sometimes something as small as a temperature change of a few degrees will put fish off food for a bit.

If you can't find any causes there, could something toxic have fallen/gotten in the tank? I've been surprised at how often this is the cause of problems in tanks.

You could try soaking your food in crushed garlic or Selcon, or even offering other types of food to spark interest.
