I just got some peppered cories over the weekend, and I have some questions about feeding them. I have read about feeding them various sinking type foods, but how do you keep the other fish from eating the food put in for the cories? I have a few platies, guppies, and neons in the tank with them. Once they are finished eating the food that I put in for them, they start to scrounge around for anything that is edible including the sinking food for the cories. They are pigs and eat everything that I put in the tank and I want to make sure that the cories are getting their fair share of food. Any suggestions?
