Clay-
GHA only, I tried to feed him nori, cheaots but he only nips at it. He is pretty cute, he climbs to the top of the tank and sticks his head and tongue out looking for algae. But he ate all mine, someone is coming sat to pick him up but if it falls through he is up for grabs. Your tank is to pretty I don't think he would make it, unless you started growing GHA...but I don't think you want that.
PS-I'm going to Quantico, VA in 3-4 months! So I may have to break down my tank soon. =(
