I would not feed freeze dried foods. These are very dry, and need to be thoroughly soaked or they will be eaten and then expand inside the fish, causing serious digestive issues. This is one reason why fresh frozen is better. But bloodworms are hazardous if fed solely, so I would wean the fish off these ASAP. And that means, do not feed them for a few weeks, and preferably not again at least until much, much later. Frozen shrimp and frozen daphnia might be better accepted. But another point to remember is that these fish are substrate feeders. They might eat flake if it has fallen to the substrate, but usually other fish get it by that time. Sinking foods are better, and Fluval Bug Bites is the best for this. Upper fish will also eat these obviously, so you may have to bee inventive to get some down to the cichlid. But bug bites are whole soldier fly larvae, and insects and insect larvae is the primary food of just about all carnivorous and omnivorous fish. These will sink fairly quicklly, what I do is add a limited amount and immediate stir them and they tend to sink as a curtain. My cories were fed this predominantly, and the loaches.
