Picked up 3 small Oto's last night to help combat some brown algae in a newly cycled tank. Thought I'd share a pic (see if you can find all 3 Oto's in the picture.) They dont have any names, partly because I cant tell them apart.
Immediately after dropping them in, they went to work and havent stopped. These guys dont seem to care if the lights are on or off. They also dont seem to be scared of their neighbors and I've seen them swim from the glass on one side to the other, right past the guppies and tetra.
I also dropped in a couple algae wafers (which I later learned was uneccessary), but they havent touched them. The guppies and platy's found them though, and I have to say that they have been a lot more "regular" since, if you know what I mean.

(Gonna have to vac the gravel 2-3 times this week instead of once if thise keeps up! :P )
