Hey, now that Iv'e bought the oto cats, and food for them, I'm having some trouble feeding them. I'm not sure if they see the algae wafers ( which blend in perfectly with my gravel ) but they keep swimming past it! They can smell it, I think. No loss though! My Molly absolutely LOVES them. She'l pick pick pick at them, then when anyone comes near, she'l chase them off. All the other fish seem to love them too. Which is the problem. The oto cats can't get to them! How can I get them to eat?
