No the problem is when they _stop_ eating. They eat algae, and if there isn't enough in your tank then they starve unless you supplement with algae wafers.
Getting ottos to survive the first month in your aquarium is the big challenge - many (many) die during that time. Once you are past that hump, and if they have plenty of food, then you should be able to enjoy them for a good long time.
