The Niger Triggerfish is a stunning addition to my 75-gallon tank. Its electric blue streaks stand out beautifully under the LED lights. It’s active but not overly aggressive, and it seems to enjoy exploring the tank. I’ve kept it for six months now and it’s still healthy and vibrant.

First time keeping a triggerfish, and this one is a hit. The black and blue coloration is impressive. I made sure to keep hard corals and avoid soft ones. It’s not shy and spends a lot of time near the back wall. Good for beginners with proper tank size.

This XXL specimen is larger than expected and looks incredible. The fin streamers move gracefully, adding a dynamic element to the tank. I’ve noticed it’s more curious than aggressive, and it seems to enjoy feeding time. Very satisfied with the purchase.
