Hi. I just moved my 3 otos from QT to my main 55 gallon tank, which is full of brown algae. They're already hard at work cleaning the glass. My question is, do I need to be supplementing their algae diet now, or can I wait until I see that they're running out of algae? I'm not too worried about sustaining them after the algae is gone, because in QT they learned to eat zucchini. I just wasn't sure if it was ok to essentially not feed them anything extra until the algae is used up. And I predict it could take a few weeks before they manage to get all the algae off the glass as well as the plants. Thanks!
