I would suggest a turbo snail, but they are so big it would probably knock everything over 
Maybe 3 or 4 smaller snails like a margarita and a couple of blue legged hermits.
Even a small serpent star would go nice. Look around and find something that appeals to you, then ask

clean up crew for a 15g nano soon to be reef 
right now the tank is in the 4th month of running, and all the big algae blooms are over that i know of. i have about 15-17lbs of live rock, and 20lbs of live sand/crushed coral. i need a crew because algae still seems to be growing on the glass. my nitrate levels have flattened out at about 20ppm, and wont go any lower. i am guessing this is why i still have a little problem with algae. i am going to a LFS(or well driving 2 hours because mine just plan sucks):mad: to get a few easy corals, and get some algae eaters. any suggestions will help,
