Overview

The Gold Spot Rabbitfish is a large, striking species with a silvery-grey body covered in fine golden-orange spots, growing considerably larger than many other commonly kept rabbitfish. It's a peaceful, effective algae grazer that offers a genuine alternative to tangs for keepers with a large tank wanting herbivorous grazing without typical surgeonfish aggression.

Like all rabbitfish it carries venomous spines in its dorsal, anal, and pelvic fins, used purely for defence, so care is needed when netting or handling this fish.

Given its large adult size, it needs a genuinely spacious tank with plenty of live rock supporting natural algae growth alongside regular supplemental feeding.

Compatibility

Gold Spot Rabbitfish are peaceful and generally get along well with tangs, angelfish, and other community fish, rarely showing the territorial aggression common among surgeonfish. They are fully reef safe and won't bother corals, clams, or invertebrates.

Care should be taken when netting or handling this fish, as its venomous spines can deliver a painful sting if mishandled, though it poses no threat to tankmates under normal circumstances.

Health & quarantine

This species is generally hardy once acclimated, though care is needed during any netting or transfer due to its venomous spines, which can also become entangled in nets. A minimum four-week quarantine is recommended, and a calm, well-fed tank supports its transition onto a varied prepared diet.
