Bad Cowrie!

[land locked]

My new green brain was nibbled on by my tiger cowrie. I have had the cowrie for a few months and he has not bothered any other corals. I have very little algae in the tank so maybe I am starving him. But my concern is the brain. I have band the cowrie to the refugium. Is there anything I can do to help my brain heal? The spots (2) are about the size of a pencil eraser.

I would make sure of good water quality. Maybe some every other day PWC`s to be on the safe side. What do the spots look like?

I could not get a picture of it for the last couple of days because it was all shrunk down. Today it finally filled full and it looks like an old scare, healing great. Thanks anyway.
