Big, brave, and beautiful, the Yellow Dottyback is a real showstopper among its genus, spending a majority of its time patrolling open areas of your reef aquarium. The Yellow Dottyback's color ranges from canary yellow to a 'dusky' purple/brown (depending on its daily diet) with dark spots in the center of each scale. This creates a subtle pattern which sometimes resembles fine lines flowing across its side.

In the wild, the Yellow Dottyback is common to lagoon reefs, tide pools, as well as in coral crevices and fore-reef slopes, feeding heavily on small fishes, as well as large zooplankters and small benthic crustaceans. At home, a 30-gallon or larger aquarium will provide a suitable environment. The Yellow Dottyback won't be intimidated by other fish and will defend its territory, even against fish two to three times its size. It will eat small ornamental shrimp.

The diet consists of meaty foods including brine shrimp and prepared frozen foods. To achieve the brightest yellow color possible, we recommend feeding a diet rich in vitamins.
