I've got 3 otos in my 15g, and most the time I keep a little piece of lettuce in there, just since I'm not sure if there's enough food for all of them.
Anyhow, usually it's only the little guy who munches on the lettuce. Last few days, I didn't put a fresh piece of lettuce in there. Tonight, the little guy was swimming around, and trying to suck him self onto the betta! Then he tried to grab one of the minnows, then back to the betta. Seemed really weird. So there's a fresh piece of lettuce in there now.
But could he possibly hurt the betta by sucking off his slime coat or something?
