Overview
The Blue-spotted Rabbitfish is a bright yellow fish covered in fine blue spotting, a peaceful and effective algae grazer that also brings genuine colour to a large reef display. Like all rabbitfish it carries venomous spines in its dorsal, anal, and pelvic fins, used purely for defence rather than aggression.
It's an excellent alternative to tangs for algae control in tanks where tang territoriality is a concern, since rabbitfish are generally far more peaceful and less prone to fighting with other herbivorous grazers.
Given its adult size and grazing needs, it does best in a large, well-established tank with plenty of live rock supporting natural algae growth alongside regular supplemental feeding.
Compatibility
Blue-spotted 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.
