Two Spot Bristletooth Tang – Ctenochaetus binotatus
The Two Spot Bristletooth Tang, scientifically known as Ctenochaetus binotatus, is one of the most attractive members of the Bristletooth Tang group. It features a brown to orange body decorated with fine blue lines, blue markings on the head, and two distinct black spots located at the bases of the dorsal and anal fins—the characteristic that gives this species its common name.
Like other Bristletooth Tangs, it has specialized bristle-like teeth used to scrape algae and biofilm from rocks, making it one of the most effective algae-grazing fish for maintaining a clean and healthy aquarium.

The Two Spot Bristletooth Tang is a hardy and active species that thrives in mature aquariums with abundant live rock. Its constant grazing behavior helps keep rock surfaces clean while contributing to a healthier reef environment.
Feeding
The Two Spot Bristletooth Tang feeds primarily on algae and other plant-based foods but also benefits from occasional protein-rich marine foods.
Recommended foods include:
- Dried Seaweed (Nori).
- Marine algae formulated for tangs.
- High-quality herbivore pellets and flakes.
- Mysis Shrimp.
- Krill and other frozen marine foods.
Reefamorous Tip: Offer dried seaweed at least three times per week using a seaweed clip or attach it to the live rock. A varied, algae-rich diet helps strengthen the immune system, reduce aggression, and maintain vibrant coloration.
