I'd like to get a small fish for my 10 gallon nano (will be turned into a 75 gallon as soon as I find a dang stand my wife likes). I do get small patches of hair algea (as of right now I have about 3 to 4 square inches scattered around the tank). So I was thinking of getting a small fish that would enjoy eating this algae. Any thoughts on what kind would be good for occasional munching of hair algea in a nano?

Other inhabitants:
Yellow/Black Brittle Star
2 Scarlet Hermits
5 Black footed Trochus
3 Nassarius
1 Baby Perc Clown
2 Cerith (Haven't seen these in a few weeks though)
Red Brain, Xenia, 2 Acro's, Green Star Polyps, Toadstoal, Mushrooms.

My parameters (Ammonia, Nitrate, Nitrite) are perfect (all zero). I haven't checked the others in 3 months though. Would I raise the bioload to high with the addition of a small fish?

Hmmm. Lawnmower blennies have the reputation for eating hair algae. I have one in my 180 and no hair algae. I have one in my 55 reef, and plenty of hair algae. Both tanks have similar lighting, rocks and filtration. So maybe it depends on the particular fish. But then again, I have tangs in the big tank too, so maybe they're the ones keeping the hair at bay. As far as your bioload, you'd be pushing it with the addition of another fish, but as long as you're on top of the housekeeping with water changes, etc. you'll probably be fine. Lawnmower blennies (Salarias fasciatus) grow to about 4-6" but you could probably find a tiny one for your tank.

I agree with Bughead Lawn mover Blenny is about the only chance for a small tank and would have to be a small for a 10 and no garente that he would touch it. No fish out there that will for sure touch it.
