Do they eat brown algae in the glass?

That would depend on the type of algae and whether the tank is planted or
not. If the Angel is not too big, you might try 3 or 4 Otos.

I've got 3 otos and I'd have to agree with those that say they get lazy.
And I only feed them once a week. The one SAE in the same tank does ten
times as much algae cleaning as the 3 otos.
