Description

The Foxface Rabbitfish or Foxface Lo (Siganus Vulpinus), is a species of fish found at reefs and lagoons in the tropical Western Pacific. It belongs to the Rabbitfish family Siganidae. The Blotched Foxface Rabbitfish (Siganus Unimaculatus) differs from Foxface Rabbitfish in possessing a large black spot below the aft dorsal fin. It is sympatric and not phylogenetically distinct, and though these two might be recently evolved species, they are more likely just color morphs.

The Foxface Rabbitfish or Foxface Lo is omnivorous, eating mostly algae and zooplankton. From time-to-time, if hungry, it may nip at corals, such as Zoantharia (zoanthids and button polyps). Though not an obligate herbivore, the Foxface Rabbitfish or Foxface Lo does require algae in its diet. In captivity, it can usually be coaxed into eating a combination of mysis shrimp, sheets of dried seaweed, and marine flake food containing algae. It is popular with aquarists due to its appetite for feather caulerpas; macroalgae that commonly overgrow the rock work in home aquaria. The Foxface Rabbitfish or Foxface Lo is highly skilled at removing this alga and will generally clear an aquarium of it within a matter of days.
