Goldline Rabbitfish (Siganus lineatus)
The goldline rabbitfish (or golden-lined spinefoot) is an active, attractive and beneficial aquarium fish. A ravenous herbivore, the goldline rabbitfish spends much of its day grazing on turf algae, film algae and macroalgae. While common and abundant in the wild, these aquacultured specimens are nevertheless a conscientious choice as the species is heavily harvested for food from the wild. Additionally, captive-bred individuals are comparatively far less likely to harbor external parasites such as Cryptocaryon.
Like other rabbitfishes, this species bears venomous spines on its dorsal, anal and pelvic fins. While not deadly poisonous, envenomation is painful and therefore extra care should be taken to avoid contact.

Goldline Rabbitfish Species Information
Though reef-associated, S. lineatus inhabits mangrove stands and seagrass meadows as juveniles while spending adulthood in protected waters such as lagoons and bays near rocky areas. It may form large or small schools. It occurs on the northern Australian coast as well as the Indo-West Pacific from India and Sri Lanka to Japan, Indonesia, New Guinea, Solomon Islands, Philippines and Micronesia.
Benefits of Aquacultured Marine Livestock
Aquacultured fishes offer a huge advantage over wild-caught specimens. For example, when bred and raised under captive conditions, they adjust more easily to aquarium life. They are also much less likely to carry disease. Even more, aquacultured specimens can better tolerate shipping stress. By purchasing aquacultured goldline rabbitfishes you support the captive breeding of marine aquarium livestock and help to make our hobby more sustainable!
