Unfortunately with these babies you sometimes just need to feed anything you have on hand in order for it to be small enough for them to eat. That being said, they need HIGH protein, and not processed protein is better than any pellet or flake. The freeze dried bloodworms should not be fed at all right now. They have hardly any nutrition despite what the bottle might say. If you do continue to feed the freeze dried and low quality flake food do so knowing you might stunt the growth of your fish.
If you can't get live, get frozen bloodworms or brine shrimp (both is best!). Then either feed that for two meals and the flake for the third, or get a supplement like Vita-chem and feed the frozen for all meals. Good luck!
