Okay oto lovers, I'm sold.

I bought 2 that are tiny. How big can they get. I have them in a 46 gal tank with 2 discus, 2 angels, 2 clown loaches, 2 painted tetras, 2 emperor tetras

Not big at all; most otos top out around and inch and a half/2 inches.

My only problem is that I don't grow much algae, so I constantly worry about them.

I fed mine algae wafers as a supplement.
