so i am feeding them algae wafers but i dont really ever see them eat. my cory cats seen to get to the wafters before the ottos even realize it is there. how can i be sure my ottos are eating?
Are the otos bellies nice and round? If they look to be in good condition, I think its safe to say they are eating. You could try doing an algae culture for them if they do not appear to be well fed.
