I have a humbug damsel that dusts/brushes/wags his tail at any perceived threat. This morning I tossed in a chunk of frozen food to let it thaw, and he swam right up, turned around, and dusted the thing off with his tail, all the while staying a little bent around so he can watch the thing. He's done this to other foreign objects, or anything large enough (not anchored to the ground) that he perceives as a potential threat.
How is this beneficial in the wild? He's a tiny fish too.. not like he could put up a ton of a fight to many other animals. Is it more of a sign of fitness like some birds that continually sing as a hawk is hot on their tail? I wouldn't think it to be incredibly wise to wag your tail in the face of an eel in the wild...
