Kayti, you can try getting him to eat pinkies by scenting them with a goldfish for now (since he's used to the smell of goldfish) and then progressing onto scenting the pinkies with minnows or guppies, or trout, salmon, or tilapia from the store. You may find that if you put some guppies in a bowl of water with some pinkies, in his efforts to hit the guppies he'll grab a pinkie instead. Same for pieces of trout or salmon; put them in the water with live guppies swimming about. Ribbons seem to be harder to get onto pinkies, but it can be done. Keep us posted!!!!
