I have recently bought two small oto's for my 10gal tank for algae control. 2 Days later, I can't see any algae in the tank whatsoever! It's a heavily planted tank with some bogwood and rocks etc. What I want to know is, do they need an alternative food source to algae? I dropped in a sinking pellet the other day which wasn't touched..
Do oto's live on algae alone? What if the supply dwindles and they go hungry?
