Blue Velvet Nudibranch (Special Order)*

Species Availability:   No stock
The Blue Velvet Nudibranch (Casella atromarginata)  is a striking sea slug with fluorescent blue markings. They only consume flatworms, and are used in aquariums to remove flatworms that have become a pest.
Special Scheduling
Because of the special dietary needs of this species, we have to ship them as soon as they are arrive at our shop, or the day after. We will have this listing available in the "Other Inverts" section when it is available from wholesalers, usually March - August. We are usually able to get them in on Wednesdays, and would ideally ship for Thursday arrival to you. Once all of the flatworms in your aquarium are consumed, you will have to find this species another home. Not all flatworms are pests.

This species requires UPS Next Day Air or Express Mail and does not qualify for free shipping.
