Headshield Nudibranch

Deep velvety black with electric blue stripes, the Headshield nudibranch is a highly specialized predator which only consumes flatworms. It is occasionally imported from the Philippines, and is also called the Blue Velvet slug. It is well known to eat the planarian pest Convolutriloba retrogemma. Nudibranch are very small and may become sucked into powerheads so all pumps should be screened. It is extremely sensitive to changes in water quality and is only recommended for expert aquarists.
