I've had my make blue throat trigger for over a year and he is big fat and eats like a pig. Starting last Friday he decided to stop eating - won't even look at food. He started sitting all day on the bottom and would move sparingly from one spot to another. I can see no signs of any sickness or scratches or anything physically wrong? It's day 6 now with no food and he is having a tough time keeping his balance, he seems to wedge himself in spots but the water is pushing him around.
Two days ago his mate the female trigger stopped eating and now she is hiding in her usual sleeping spot all day and is showing no interest in food. I'm afraid she is going to have the same fate?
I have about 12 other fish and they are showing no ill signs at all. My corals are doing fine and water paramaters look good.
Any suggestions on what might be causing this and anything I can do save these guys?
