The Achilles Tang (Acanthurus achilles) is a breathtakingly beautiful and highly prized species for experienced marine aquarists. This fish is instantly recognizable by its velvety jet-black body and a vibrant teardrop-shaped orange spot on its tail (or heal if we want to honor the Greek legend Achilles that this fish was named for). With its stunning appearance and graceful swimming style, the Achilles Tang is often the centerpiece of a mature and healthy saltwater aquarium. They are active grazers that play a valuable role in controlling algae, but they are best suited for expert hobbyists due to their specific care needs.

The fish looks exactly as described. It’s a bit shy at first, but once it settles in, it becomes a regular sight swimming through the tank. I appreciate the algae control it provides.
