Chevron Tang (Hawaiian Bristletooth)

Origin and Distribution

The distribution of this fish extends from Hawaii southeastward to japanese Polynesia, southward to central Polynesia, westward to the Marianas Islands, and probably to many different adjoining areas. The adults inhabit the shallower oxygen enriched waters near the surge zone of the reef the place rocks and crevices are discovered, usually gathering in faculties. The juveniles want the deeper, finger coral inhabited waters and dwell singly. 

Colours and Markings

The juvenile stage of the chevron tang may be very colourful with deep purple, orange, and pink marking. In captivity, the chevron tang appears to retain its juvenile colours for fairly some time longer than it appears to within the wild. There are a number of instances the place the chevron retained its juvenile colours for greater than three years, whereas within the wild, the chevron appears to shift to its grownup colours after a 12 months.

As soon as within the grownup stage, the pink and purple colours fade and the coloring turns into darkish brown, virtually black, with the edges of the physique and head marked by many superb, horizontal, yellowish-gray strains. As a result of the grownup stage of the chevron tang is analogous in look to that of a ​kole (yellow-eye surgeonfish) tang, it’s typically known as the Hawaiian black kole. The variations are that it doesn’t have the yellow ring across the eye, the physique is darker in colour, and its pectoral fins flip a darkish brown colour, the place the kole’s pectoral fins are virtually clear.

Tankmates

This isn’t a very aggressive fish, so it could get picked on by extra aggressive surgeonfish. It’ll normally get alongside nicely with different tank inhabitants, excluding its personal variety, and it hardly ever bothers motionless invertebrates. Its weight-reduction plan makes it a terrific complementary companion for different peaceable surgeonfish such because the yellow tang or the Pacific sailfin tang, although it’s essential to regulate compatibility.

Within the wild, a cleaner wrasse would usually preserve a tang parasite free. Alternatively, you may add neon gobies or cleaner shrimp to your house tank to assist them take away parasites that may crop up.

Chevron Tang Habitat and Care

The minimal aquarium measurement urged for this fish is at the very least 135 gallons. It’s a huge swimmer and desires lots of house.

They may profit much more with the inclusion of dwell sand.

They use their tooth to raise and sift by means of varied sorts of rocks, sand, and different surfaces and use their mouths to hoover up the algae. Within the aquarium, you’ll usually see little lip marks on the glass the place algae was once.

They’re prone to micro organism ensuing from natural buildup which deteriorates water high quality. They may want vigorous filtration, protein skimming, and common small water modifications.

Chevron Tang Weight-reduction plan

Though this fish is a herbivore within the wild, with its essential weight-reduction plan consisting of marine microalgae development, you can too feed it shrimp and different meaty meals in captivity. The vast majority of their consumption will likely be vegetable matter. The chevron tang is superb for maintaining the brown (diatom) algae and inexperienced hair algae in verify in your aquarium.

They use bristle-like tooth to eat detritus which incorporates minute algae reasonably than the filamentous algae eaten by different tangs. The Ctenochaetus species, known as each the bristletooth or combtooth tangs, have a number of rows of small versatile comb-like tooth (as much as 30 tooth) together with a protrusive pouting mouth. 

Present a lot of marine algae, ready frozen formulation containing algae or spirulina, frozen brine and mysid shrimp, and flake meals. Use a vegetable clip to stick Japanese nori seaweed to the aquarium glass. Feed 3 times a day in smaller quantities as a substitute of a giant amount as soon as a day. As steady grazers, they may profit from this. This can even preserve the water high quality higher over an extended time frame.

Sexual Variations

This species doesn’t appear to have any distinctive figuring out traits between the sexes. Males will assume brighter courtship colours throughout mating intervals.

Breeding the Chevron Tang 

The chevron tang, like different surgeonfish, is pelagic, that means it is a free-spawner or egg-scatterer that spawns in teams. The feminine ejects her small eggs within the water column after which the male swims over and thru the egg cloud fertilizing as he goes. The feminine produces a whole bunch of eggs at a time a lot of occasions per 12 months, normally within the spring and summer season months.
