I just added some peppered cories to my community tank. They are the only bottom feeders in this tank. While they aggressively go for the flakes I am feeding the other fish every other day, I am trying to make sure the cories are well fed. Aside from leftover flakes every other day I am feeding them one shrimp pellet each and one quarter algae wafer each on alternate days. Is this enough food for the cories?
