dried baby shrimp, krill, market shrimp, white meat fish filets, cichlid pellets.....
I could add more to that list, but I need someone else to pick up here!!
Live feeders carry so many diseases that your fish can contract. It's better and healthier to wean your fish off of them, and onto prepared foods.
Goldfish are very fatty and are the equivalent of eating crisco.....not very good for ya.
if you MUST have feeders, I would suggest getting a pair of convict cichlids and breeding your own healthy feeders. BTW, GUTLOAD first!!
