About Striated Surgeonfish

The striated surgeonfish has an elongated, slightly compressed brown or tan body with prominent vertical darker stripes running from head to tail. It features a distinctive comb-like dentition (hence the genus name Ctenochaetus), a venomous spine at the base of the tail characteristic of surgeonfishes, and a pointed snout adapted for grazing on algae and detritus.

Key facts

Difficulty Level
Moderate difficulty. The striated surgeonfish requires a well-established reef with mature biological filtration, consistent water parameters, and abundant algae or supplemental herbivore foods. It is less aggressive than many tangs but still needs adequate space and stable conditions.
