BH is still lingering in the hobby but isn't really necessary anymore. There are many more easier to use and healthier substitutes. One of the better pellets (NLS) is often much more suitable as a diet than any mammalian based foods. If you want to add variety, frozen mysis is a good choice, and the shells add much needed roughage to the diet. Any kind of frozen invertebrate is usually a good choice and would simulate their natural diets. Stay away from brine shrimp as it is pretty much worthless nutritionally. An exception to that is the spirulina enriched variety which provides a good amount of vegetable matter.
