Matted Filefish Acreichthys tomentosus

[EmilyB]

Just wanted to update, seems like covering the tank made all the difference. He's been here roughly a year and a half.

I could swear that this fish sheds. He gets a real yellow sheen, then disappears for a few days and I think he's dead. In fact, we are sure we found a floating yellow tail....

Then he reappears all shiny and new and back to brownish. Anyone seen anything like that?
