Contrary to what previous posters said, do not feed your marines FW feeders... they will shorten the lifespan of your fish, with "fatty liver disease". If you cannot buy marine feeder fish then don't use feeder fish. Mollies/goldfish etc have the wrong nutritional profile, they are far to high in fat which is very hard on your marine predators, they are used to eating a much "leaner" meat. If you are having dificulty switching to prepaired foods, start by feeding live shrimp to tigger the "feeding instinct" (ideally grabbing one with a feeder stick so they get used to the stick which is needed later), then every other shrimp you feed give them a dead one on the feeder stick (with the feeder stick you can make the dead shrimp "move") if they eat the dead one readily keep feeding them dead ones. At some point you will be able to get them to eat only dead ones off the feeder stick, without using live ones first. At this point you can move to thawed frozen foods. If you want to switch them to pellets, add some pellets to your frozen food, slowly decreasing the ammount of frozen you use and increasing the ammount of pellet, If you have to keep using the feeder stick to entice them to eat, as fish learn that the stick means food.
