Got him a few days ago looked like this
Now he looks like this on one side
I have a two spot bristle tooth that occasionally chases him just a little bit form what I have seen
A few days ago, everything was looking good all of a sudden after feeding the corals oyster feast, one of my hammer polyps started to close a little bit so I did a water change only 10 gallons and today a second one looks a little more closed.
It used to look like this less than a week ago
