I got 2 otos for my 25 I also have a pleco in there, and I was wondering how often I should feed them an algea tablet? I was thinking every 2 days or something, because they still need to clean the algea in my tank. I have never kept otos before.
well if there is a constant food source like algae or left over food from other fish then once a week is good enough. You should also look into gettin a veggie clip and putting zucchini in there, they like it alot.
