FishhyRen,
Thank you for your post. Although we list live black worms for some species, we currently do not carry them. Most of the species we carry can be fed a variety of foods. If you would like to send us a p.m., or call us, with the species of fish that you are interested in, we will be able to suggest other foods that are nutritionally complete.
