An observation about fish digestion

[justinl]

that is a very good question and I can't really answer it. I think it is safe to assume it will depend greatly on the life style of the fish. Lookdowns and tangs probably store fat less than a grouper for example. Probably not stored as fat either but as soluble lipids in their blood; im just speculating now though. i would expect fat in a fish to serve as insulation but not as an energy store. I could be wrong though. wonder if it might screw up their buoyancy after a point?
