The Niger Triggerfish is a visually striking addition to my 200-gallon tank. The color shifts between days are fascinating, especially under different lighting. It’s active and makes a soft grunting sound when feeding. I appreciate the unique appearance and the way it interacts with the rock structure.

I’ve had this fish for three months now. The color changes are noticeable and quite beautiful. It’s not shy and enjoys exploring the caves. The only thing to note is that it occasionally moves rocks around, so some rearrangement is expected.

A great choice for an aquarium with visual interest. The red teeth and blue-green face highlight are very distinct. It’s peaceful but vocalizes when it’s active, which is a nice detail to hear.
