The One-Spot Foxface (Siganus unimaculatus) is a striking and highly recognizable reef fish, known for its bright yellow body and distinctive black facial mask with a single dark spot on its flank. It is both decorative and functional, as it actively grazes nuisance algae in marine aquariums.

Behavior & Compatibility

Foxfaces are peaceful and suitable for mixed reef aquariums. They can be slightly shy at first but usually adapt well and become confident swimmers. Best kept singly unless the aquarium is very large.

Like other rabbitfish, they possess venomous dorsal spines for defense. They are not aggressive but should be handled carefully.

Feeding

Primarily herbivorous. Provide:

Marine algae sheets (nori)

Spirulina-based foods

High-quality herbivore pellets

Frozen foods (mysis, brine shrimp) as supplement

Regular feeding helps reduce the risk of coral nipping.

Why Choose a Foxface?

Excellent natural algae control

Bold coloration and strong visual presence

Hardy once established

Suitable centerpiece fish for medium to large reef tanks

Important Notes

May change coloration when stressed (mottled camouflage pattern).

Ensure stable water parameters and ample swimming space.

Drip acclimation recommended.
