Kole Tang

About

The Bristletoothed Surgeonfish (Ctenochaetus strigosus) is a compact, reef-associated tang endemic to the Hawaiian Islands and Johnston Island. A notably restricted range that makes it one of the more geographically specialized surgeonfish in the hobby. In the wild it spends its days picking over coral, rock, and rubble substrates, using its distinctive comb-like teeth to whisk detritus and algae off hard surfaces as it feeds. That specialized mouth is the defining feature of the genus, and it makes this fish a genuinely useful addition to a tank with nuisance algae accumulation. Adults develop a subtle but appealing look. A dark brownish body with fine horizontal streaking and, in healthy specimens, a yellow ring around the eye that gives the fish one of its alternate names, Goldring Bristletooth. It is a solitary animal in nature and largely active during daylight hours. In the aquarium it tends to be one of the more manageable tangs temperament-wise, though it still requires the open swimming space typical of the group and the dietary variety that keeps surgeonfish thriving long term. Intermediate-level experience is recommended, partly because maintaining appropriate conditions and nutrition is essential to preventing the color fade and health issues this species can develop under suboptimal care.
