Goldline Rabbitfish

Siganus lineatus

The Golden Lined Rabbitfishis abeautiful, interesting, and hard-working algae eater for larger aquariums. They are ravenous herbivores that spend most of their time visibly swimming out in the open, grazing on nuisance algae.

They have a light blue body with metallic gold lines, dots, and dashes and a big bright lemon yellow blotch at the base of the tail. Rabbitfish may be added to a reef tank “with caution,” but theymay eat many coral species such as Xenia and fleshy LPS. Keeping them very well-fed can help to curb their appetite for coral.

These fish can grow large – more than a foot in length. They are also very fast, active swimmers, so they should be housed in an aquarium of at least 100 gallons. Longer aquariums at least 6 feet in length are ideal for adult rabbitfish.

They are peaceful toward other fish but may fight with similar species. They make great additions to both peaceful and predator tanks because their venomous spines deter predatory fish from eating them. Please use caution when handling rabbitfish and when cleaning the tank, as their sting can be painful.
