Someone asked what an otto is. Well its a real name is ottcinclus affins I think I spelled that right. They get about 2-3 inchs tops, and make a good algae crew. Like I said in my post, I have 3 in each tank and they do great. Oh yeah, sometimes I hear that the ottocinclus is imported in many different species. I dunno really, check out the Krib, under the plant section for algae. Gives you our choices for taking care of algae with fish.
