Blackline Fangblenny
Meiacanthus nigrolineatus
Description:
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 into a broken line before terminating. Some
geographic variants exist.
Natural
Ecology: 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. This
species is mimicked by Plagiotremus townsendi, who opportunistically
attack other fishes to feed on scales, fin, and flesh
tissues. Meanwhile, this Meiacanthus nigrolineatus is
also mimicked by Ecsenius gravieri who is a harmless herbivore.
Indigenous
To: This species occurs in the Red Sea and the
Gulf of Aden.
Behavior:
This species ignores other species. Its evolved immunity
from predation rendered it unnecessary to hide. It is
bravely present in mid-water, hovering near its favorite
rock crevice.
Compatability:
Usually ignores corals and most invertebrates.
Food:
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 will be readily accepted.
These beauties have great personality!
