I very much like the idea of live foods and I hatch my own brine shrimp for feeding to my tank. It's funny to watch the clowns eating them, it looks like they are gulping at nothing. Do you raise your own blackworms? Do you have a source for purchasing them? How do you feed them to the fish, in a strainer? I found this vendor.
