The tiny pygmy filefish grows to only 3 or 4 inches, so it is easily kept in an aquarium as small as 55 gallons. Its small size, green coloring, and an unusual round, but flattened shape make it an interesting aquarium acquistion.

In nature this fish is found among bottom coverings of the waters of South Japan and South Korea. This species appreciates plent of hiding places in an aquarium, as it can be shy at first. It eventually gains confidence enough to swim out in the open.

Once adjusted to aquarium life, it is fairly hardy and will accept a variety of foods. Although, this species is more docile than typical filefish, caution should still be taken when chosing tank mates.
