Blackline Blenny (Meiacanthus nigrolineatus)
This species has a blue-teal head that blends into a yellow tail. Black spots are located along the anterior (near the head) dorsal fins, confined only to the soft tissues that inter-digit the fin rays. The common name is derived from a prominent black stripe which originates from the eye and runs longitudinally about half or two-thirds the length of the body, where it becomes a broken line before terminating. Some geographic variants exist.
Meiacanthus nigrolineatus is a carnivore of zooplankton and other bite-size invertebrates. Like most members of this genus, they have evolved a stinging bite for protection against predators. They have also evolved bright colors as an effective reminder to predators, who distinctly associate this species with a stinging experience. Interestingly, other non-venomous species have evolved to look like some Meiacanthus species in color and shape, so that predators also avoid them. The Meiacanthus nigrolineatus is mimicked by Ecsenius gravieri who is a harmless herbivore.
This species occurs in the Red Sea and the Gulf of Aden.
This species ignores other species. They are often present in mid-water, hovering near its favorite rock crevice.
Usually ignores corals and most invertebrates.
Proaquatix specimens have been weaned to take aquarium pellets and flakes. Freshly frozen invertebrates such as ocean plankton, Mysis shrimp, brine shrimp, and chopped squid.
