Ctenochaetus binotatus: an Efficient and Discreet Little Cleaner Surgeonfish

The Ctenochaetus binotatus is a peaceful and useful little surgeonfish, perfect for medium to large reef aquariums. This specimen belongs to the group of biofilm and microalgae grazers and plays an essential role in maintaining the biological balance of the tank.

Its brown body with bluish or greenish reflections is speckled with small dots and fine streaks, characteristic of the Ctenochaetus genus. It owes its species name "binotatus" to the presence of two dark spots visible on each side of its caudal peduncle. This visual signature gives it a unique and elegant appearance.

Peaceful Behavior Suitable for Community Tanks

The Ctenochaetus binotatus is known for its calm and non-aggressive temperament. It coexists easily with other marine species, including other surgeonfish, making it particularly suitable for community aquarium life.

Thanks to its small size, this young specimen integrates easily into an already populated reef tank, provided the decor is well-structured with areas for free swimming and surfaces to graze. It is not very territorial and primarily moves in the lower and middle areas of the tank.

An Active Cleaner of Decor and Live Rocks

The Ctenochaetus binotatus grazes on microalgae, organic films, and fine particles of plant matter deposited on rocks and glass. Unlike other more classic Acanthuridae, it uses its rasp-shaped mouth to scrape surfaces without damaging them, making it a discreet yet indispensable ecological ally.

It actively contributes to the cleanliness of the reef decor and limits the proliferation of undesirable filamentous algae.

An Adapted Plant-Based Diet

Although primarily herbivorous, this little Ctenochaetus binotatus also appreciates varied inputs. It should receive daily:

• Fresh or dried nori algae attached in the aquarium.
• Vegetable pellets, spirulina-based flakes, and fiber-rich preparations.
• Occasional supplements of mysis, krill, or artemia to support its growth.

A well-balanced diet ensures good development, active behavior, and increased resistance to diseases.

A Discreet, Useful Surgeonfish Well-Adapted to Captivity

The Ctenochaetus binotatus is a wise choice for aquarists looking to introduce an effective and peaceful algae grazer into their marine aquarium. Its small size allows for easy integration, while its functional role makes it a fish that is both useful, robust, and aesthetically pleasing.

Ideal for stable reef aquariums, the Ctenochaetus binotatus surgeonfish is an essential fish for maintaining the cleanliness and balance of the live decor, from its first few centimeters.
