Hi everyone. This morning I took a trip to one of the local saltwater specialty stores around rochester(lucky me there is like three of them and they are good)and I came home with what the guy called "black snails". He said they were batter then turbos, and they were cheaper. I have been having green hair algae probs lately so I decided to try a couple and man, do they kick ass! They eat hair algea like champs and every other type on the way. I don't know much about snails because I just bought a bunch of astreas when I first got my tank and they sucked. These are great. [Grin].
