Can anyone please tell me anything about the dietary requirements of this cool little fish? I purchased one over the weekend and was told by my LFS that it eats hair algae. Their is some in my tank and the Sailfin appears to be scraping it off the rocks, but I would like to know if this will provide enought nutrition for him. Currently it is housed in a 75 gallon tank with 48 lbs of live rock. The only other herbivores in the tank are 14 turbo snails, one mithrax crab, and 5 hermits. Will my tank produce enought food for my fish with these other competitors in it? :?:
