rather than gettting any fish to clear up the algea, i would black out the tank for a couple days. I plan on doing that with my tank, which was sigested by someone on my algea thread (i don't remeber which). what other fish do you have in this tank? my Corys nibble on the algae and so do my guppies. I wipe the walls down when i do my water changes and my algea hasn't gott much worse.
