So about 10 minutes ago I threw in 6 pellets of ken's premium cat fish food (says good for cory cats), and i expected them to break apart like the Wardley shrimp pellets I had been using, but alas, they stayed solid. My panda cories found some, seemed to try to nibble on them but they wouldn't break apart! It seems like the pandas are giving up on them. I thought I was buying a great food since I heard so much about Kens but this stuff seems too solid for the corydoras? Or does it just need to sit in there a while longer?
