Ive had him 4 years. Hes looking skinny and he looks like hes confused... if that makes sense. Hes does not go for the food like he used to. Inface the past few weeks hes been getting less and less because everyone else eats it all before he realizes whats going on. And now for the past 2 days hes just been laying on the sand bed all day. He always went under the sand at night, but never layed on the sand during the day. He used to zoom around all the rocks all day. Hes the biggest fish in the tank out of 1 clownfish, 1 flame hawk, 2 firefish, and 1 banggai cardinal, and nobody ever bothered him anyway.
