: On Saturday afternoon/evening I added a healthy looking Blue Hippo Tang to my tank, and it has hidden in the back corner ever since. I feel bad for the fish, it kind of props itself on the live rock and the side of the tank and rests. A few times I have seen it poking around the reef, peeking around, but it mostly rests in its corner. There is some green algae back there, and I have seen it eat a bit. When it swims, it swims normally.
I picked this one out, over another, more active blue tang, due to its smaller size, about 2 inches. It was in a tank with two percula clowns, and was staying away from them. I have two perculas, one med. one small, that stay on the opposite side of the tank, where they like to hang out. They got along great with the Convict Tangs I had in there, but I moved the Convicts out make room for the Blue Tang.
My 55 gal
is full of live rock and is getting overgrown with various green algaes. I had hoped that a "grazer" like the Blue Tang would be very happy there. The Convicts grazed non stop and grew really fast -I never had to feed them.
Is there hope for my Tang?
