Dojos and otos?

[grizzlyone]

Got a question folks...

I've got a bit of a brown algae issue. I'm in the process of adjusting the tank (lighting, etc), put was wondering if as a purely temporary measure I could but some otos in the tank. Are the dojos (4 of them between 3-4 inches) gonna snack on them or are they likely to be safe? The rubber lip pleco doesn't seem to like the brown stuff.
