The Half Black Mimic Tang (Acanthurus chronixis), also known as the Orangeshoulder Surgeonfish, is prized for its striking appearance and peaceful demeanor in saltwater aquariums. Originating from the Indo-Pacific region, they thrive in reef environments with ample hiding spots among live rock formations. Reef-safe and herbivorous, they reach sizes of 8-10 inches and can live for 5-7 years with proper care. Their diet should include marine flakes, pellets, and algae to maintain health and vibrant coloration. While primarily wild-caught, sourcing from reputable suppliers like Saltwaterfish.com is recommended. Compatible with various fish and invertebrates, they require a tank size of at least 120 gallons with stable water parameters. Maintaining stable water conditions with a pH level between 8.1 and 8.4, a salinity level of 1.020-1.025, and a consistent temperature range of 74-82°F (23-28°C) is crucial. Choosing tank mates wisely, such as Firefish Goby, Coral Beauty Angelfish, Lawnmower Blenny, Royal Gramma, and Yellowtail Damselfish, ensures a harmonious community. By selecting Saltwaterfish.com, you ensure the acquisition of a well-acclimated specimen, enhancing the beauty and vitality of your marine aquarium.
