Atlantic Blue Tang (Acanthurus coeruleus)
Max Size: 9 inches
Reef Compatible: Yes
Minimum Tank Size: 180 gallons
The Blue Caribbean Tang, also known as the Atlantic Blue Tang, Blue Tang Surgeonfish, or simply the Blue Tang, possesses an oval body adorned with striking markings that transform as the fish progresses from juvenile to adult. Juveniles display a vibrant yellow coloration with two blue bands near the eyes and additional blue markings on the edges of the dorsal and caudal fins. As they mature, the blue hues intensify, with horizontal markings spanning the entire body. The tail may retain a yellow coloration.
To accommodate the Blue Caribbean Tang, a spacious aquarium of at least 180 gallons is required to provide ample swimming room. It is important to note that this species exhibits aggression towards other Tangs and Surgeonfish, but generally maintains a peaceful disposition towards other fish species.
While the Blue Caribbean Tang will consume meaty foods alongside other aquarium inhabitants, it is crucial to provide them with an abundant supply of marine-based seaweed and algae. This dietary inclusion promotes a strong immune system, reduces aggression, and enhances overall health. Offering dried seaweed attached to a rock or using a veggie clip is recommended, and they should be fed at least three times per week. Products such as Sea Veggies, Seaweed Salad, and Ocean Nutrition are ideal options as they are user-friendly and provide the necessary nutritional benefits.
