Alright so this is somewhat of a multi-part question. I appear to have the Diatom algae in my tank. It's not that bad (yet, as I just cleaned the tank), at first I thought it was the cyano stuff, but it's not really a red color, it's more like a rust which is how Diatoms is described and it would make sense that I'd be getting it now. But! My question is this, I have a chocolate chip starfish who's not really staying on the rocks, he's just on the glass most of the time. Should I still get a grazing snail to help the problem or would those 2 end up having problems with each other? I thought about getting a scooter blenny, but I don't know if they'll do the same job as the snail. Plus I don't know if it would conflict with my starfish. I already know about making sure the blenny eats prepared food, which it does. I already asked back when I was going to get one but I figured I wouldn't need one because I already had a starfish. Anyway, thanks for the help!
