I bought this triggerfish for my 75-gallon tank and it’s been active and territorial. It’s not for beginners, but once you understand its behavior, it can be a striking addition. I had to remove a few corals early on, but it’s a bold and colorful presence.

The fish arrived healthy and looks vibrant. I expected aggression, and it’s definitely aggressive. I’ve had to keep it away from other fish and ensure it has plenty of hiding spots. Not ideal for small tanks or reef setups.

This triggerfish adds a lot of visual interest. After a few weeks, it started cleaning the tank floor and showing interest in food. I’m cautious about its interactions with other fish, but it’s a unique and bold choice for an intermediate aquarist.
