yup, brineshrimp and blackworms will work. so will whiteworms, bloodworms, mosquito larvae, daphnia, grindal worms, depending on the size of the fish maybe microworms.
Cories, tetras and gouramies? I think they're quite easy. My gouramies excepted falkes, tetras also! And they won't hesitate to have bloodworms, water-flea,,,
