The Humu Rectangle Triggerfish is a striking addition to my 200-gallon tank. It’s active and curious, often exploring the rock formations. I feed it a mix of squid and clams daily, which keeps its teeth worn down. It makes a gentle grunting sound when it’s active, which is quite unique. The yellow V-pattern on its back is very noticeable and adds to the visual appeal.

I bought this fish for my marine setup and it has adapted well to the 180-gallon tank. It’s not shy and spends a lot of time near the caves. Feeding it krill and shrimp has been essential. I’ve noticed it occasionally moves rocks around, which is a bit surprising but not damaging. Overall, a beautiful and interesting species.

The fish looks exactly like the photos—pearly white face with blue and black eye stripes and the yellow V-pattern on its back. It’s very active and seems to enjoy the environment. I’ve been feeding it a varied diet of meaty foods, and it’s thriving. The sound it makes is subtle but noticeable during feeding times.
