Mosaic Leatherjacket Filefish

(Eubalichthys mosaicus)

Leatherjackets should be added to well established aquariums with plenty of room to swim. Plenty of rock work with caves, cracks and crevices should be provided for grazing and hiding. Leatherjackets received their name because of the texture of their skin. They are slow swimmers, an aquarium with low water flow is required. Feed a well balanced diet of marine meaty and algae based foods. Leatherjackets may eat aiptasia and will pick at coral, algae, sponge, molluscs, crabs, snails and sea urchins. If not readily eating provide live adult enriched Brine Shrimp or Black Worms. Leatherjackets are generally shy and secretive and should only be housed with other peaceful fish.

Mosaic Leatherjacket are also sometimes known as the Deep Bodied or Dinnerplate Leatherjacket. Not often seen in the aquarium trade. Quite distinct and colorful with yellow, orange and blue coloring, as they mature the orange darkens to black and the blue begins to fade and its body will begins to lengthen. Mosaic Leatherjacket can grow to almost 24".

We recommend a minimum aquarium size of 250 gallons or larger for this species.
