Algae taking over my tank, please give me a list of tropical algae eaters

I have two 10 gallon tanks. In them I have an Oto and a Pleco. The Pleco, how ever, we are searching for a new tank for (since he will soon grow too big) and currently they aren't doing a good job of keeping the tank clean.

there's dark green algae everywhere! I'm going to get 2 to 3 more Otos to stay in the female guppies' tank, while the Pleco can stay in the males. The male's tank, however, is where the Pleco and Oto are staying now, since it's covered in slime, and the job isn't getting done.

Anyway, I'd like a list of different algae eaters that do great in a tropical community. I DO NOT WANT GHOST SHRIMP!

Thanks a bundles :)

HI Morgan, haven't seen you around in awhile. You've got some decent input here from everyone. To treat algea you have a combination of things. Starting first with the lighting, make sure that there is no direct exposure to sunlight, and that your tank lights are on like a normal day, say around 8-10 hours and then just cut them off. Try to simulate a natural light cycle in your tank.

Algone as mentioned by Donnie is a good product. I've used that and it seems to work fairly effective. And the others talking about the nutrients in the water as well, keeping up with the regular maintenence. That will help put it under control, but one thing I want to add outside the scope of the other answers here..Check your tap water source for nitrates and phosphates please. You may well be doing everything you should, but the problem will be that nitrates as well as phosphates are already in the water to begin with.
