Hawaiian Blue Eye Tang - Ctenochaetus binotatus

Hawaiian Blue Eye Tang

The Hawaiian Blue Eye Tang offers exceptional functional utility by constantly consuming film algae and detritus. Specifically, its specialized bristle-tooth comb mouthparts scrape organic film cleanly off aquarium glass and live rocks. Subtle longitudinal orange striping complements radiant sky-blue iris rings surrounding each eye. As a result, this diligent worker keeps biological surfaces clean throughout mature reef aquascapes.

Hawaiian Blue Eye Tang Tank Dynamics, Acclimation & Diet

Establish ample live rock surfaces before introducing this specialized bristle-tooth grazer to your display. Supplement natural grazing with spirulina flakes, marine pellets, and finely chopped frozen foods. Additionally, maintain stable alkalinity and pH levels to support smooth acclimation during introduction. This solitary grazer rarely bothers ornamental invertebrates or sessile coral species.
