Atlantic Blue Tang: The Iconic & Hardworking Algae Grazer

The Atlantic Blue Tang (Acanthurus coeruleus) is one of the most recognizable and popular fish in the marine aquarium hobby. Famous for its dramatic color changes, this tang starts as a stunning solid yellow juvenile before transforming into a vibrant blue or deep purple as an adult. It is a graceful and active swimmer that requires plenty of open space to roam. While it is generally peaceful with most other species, it can be territorial towards other tangs, so it's often best to introduce it to the tank last. As a herbivore, it is a fantastic algae-eater, making it a valuable and hardworking member of any clean-up crew. It is completely reef-safe and will not harm corals or invertebrates.

Why the Atlantic Blue Tang is a Great Choice:

• Iconic Appearance: Its brilliant coloration and dramatic color transformation make it a true showpiece.
• Excellent Algae Control: It tirelessly grazes on nuisance algae, helping to keep the tank clean and healthy.
• Completely Reef-Safe: It won't harm corals, clams, or other invertebrates.
• Adds Energy to the Tank: It adds a lot of energy and movement to a spacious aquarium.
