| actually, unenriched live artemia is a rather bad food for anything. however, they can be enriched with just about anything you'd like to get inside your fish. selcon is a good enrichment, as is spirulina. beta glucan is a great one for boosting the immune system.
the favorite food of marine bettas is live shrimp, such as ghost shrimp. unfortunately, ornamental shrimp fall into this category as well.
