Flashing Tilefish pic

[Coralgurl]

This morning I checked both tanks as I normally do, and found my tilefish stuck to the power head - dead. Not sure why. I noticed abrasions on his head but don't know if something in the tank caused it or just the powerhead. I had the tank covered to keep him from jumping, he was very active, ate like a pig and had become quite "social". He didn't flash often and if he did, it was at feeding time and did it to the other fish. Hate losing fish...
