Pearly white with rows of bright orange spots and pale blue highlights, it spends the whole day picking up mouthfuls of sand and sifting them through its gills. It is a beginner-friendly fish with one catch: it relies on the microfauna in the sand, so it does best in an established tank with a deep fine sand bed and regular supplemental feeding.
