Description
Blue Scrawled Rabbitfish (Siganus puellus)
Overview
The Blue Scrawled Rabbitfish, also known as the Scribbled Rabbitfish, is a stunning and hardy reef species featuring a yellow body covered with intricate electric-blue lines and spots. Peaceful, active, and an excellent algae grazer, this fish adds both beauty and utility to large community or reef aquariums.
Origin
Found throughout the Indo-Pacific region, including Indonesia, the Philippines, and the Great Barrier Reef, Siganus puellus inhabits coral reefs, lagoons, and seagrass beds—often seen in pairs or small groups.
Feeding
Primarily herbivorous, the Blue Scrawled Rabbitfish thrives on a diet of marine algae, seaweed, and plant-based foods. Supplement with spirulina, nori, and herbivore pellets, along with occasional meaty foods for variety. Feed 2–3 times daily to maintain health and color.
Tank Mates
Peaceful and reef-safe with caution. It coexists well with tangs, angelfish, wrasses, and clownfish but should not be housed with aggressive or fin-nipping species. May occasionally nip soft corals if underfed.
Aggression
Generally peaceful, though mild territorial behavior can occur toward similar-shaped fish. Provide ample swimming space and hiding areas to minimize conflict.
Experience Level
Recommended for intermediate aquarists. Hardy and adaptable, this species thrives in large, mature aquariums with stable conditions and plenty of live rock for grazing.
