I'm completely at a loss here. I have cory cats and my betta together in a 10 gallon. The problem is, my betta boy is a pig monster. So, I drop in a sinking wafer for the cats and he finds it and eats it. I've tried feeding them in different areas of the tank, hiding the wafer under plants, and netting my betta for a few minutes while feeding the cats. Unfortunately, the cory cats don't eat right away. It seems to take them at least half an hour to figure out where the food is (I know it's bad to leave food in the tank, but they do eat it and I'm not sure how to get them to eat otherwise). By this time, piggy has found the wafer, eaten it, and is looking extremely self satisfied and plump.
I've even tried distracting him at the other end of the tank while I hide the food! No dice. So, anyone have any suggestions for keeping my piggy away for half an hour to an hour while the cory cats figure out where the food is?
