The One Spot Foxface, also known as the Blotched Foxface, is an exceptional utility fish and a highly popular addition to the marine hobby. Showcasing a vibrant, bright yellow body contrasted by a stark black-and-white patterned head, this species is easily distinguished from the standard Foxface by a prominent dark spot or blotch located on its upper rear flank. They are legendary for their relentless appetite for nuisance aquarium algae, making quick work of green hair algae, bubble algae, and turf algae. While they are peaceful community members that coexist easily with most fish, aquarists must exercise caution during tank maintenance, as the Foxface possesses venomous dorsal spines that can deliver a painful sting if handled.
