African Blue Tang
The African Blue Tang (Paracanthurus hepatus), perhaps better known as the Blue Tang, or, if we must, Dory, is one of the most popular and recognizable marine aquarium fish in the world. This vibrant surgeonfish is admired for its striking, deep blue body, black palette-shaped markings, and yellow tail. A healthy African Blue Tang is a fast, active swimmer, making it a spectacular focal point for a large marine display tank.
The African Blue Tang is generally peaceful towards most tankmates but can be territorial toward other tangs, particularly those of similar shape or color. Like all surgeonfish, it possesses a sharp, scalpel-like spine near its tail, which is used for defense and territorial purposes.

The African Blue Tang is a stunning addition to my 120-gallon marine tank. It swims actively and adds a lot of visual appeal. I’ve had it for over a year and it’s still healthy and vibrant. Just make sure to avoid other tangs to prevent conflicts.

Beautiful fish with a deep blue body and bold markings. It’s active and keeps the tank lively. I noticed it became slightly aggressive when I added another tang, so I removed it. Now it’s peaceful with my clownfish and gobies.

This fish is exactly as described. The color is vivid and it swims gracefully. I maintain stable water parameters and it has adapted well. It’s a centerpiece in my tank and very easy to spot during the day.
