My oto's are fantastic algae eaters. The only issue with them is they have to go into a very well established tank because most of them are starving when you get them. Suppliment their diet with algae wafers occasionaly and they will be fine in a well established tank. Mine swim all over the place and they also will shoal together. I love them. I lost two and plan on getting a couple more this weekend. They were alive for almost two years.
I was curious about what that article said about the false algae eater thing. I wonder how you tell the difference between the two? I wouldn't go for either though since they get so darn big. I remember talking to Bombalurina about these and she said the all are agressive. She has experience with them. Heck I have even seen a pleco sucking on a fish before! Never a little Oto. Depending on your tank size I would do at least three. They are only a couple dollars and they are very active alone and especially in groups. I love them :3 Don't tell my Pleco.
Keep yourself clean and bright, for you are the window through which you must see the world.
