The fish is active and curious. It has adapted well to the 75-gallon tank with corals. I noticed it doesn’t damage the reef, which is great. It’s semi-aggressive but not overly so. Needs a stable environment and regular water testing. Overall, a solid addition to a reef setup.

I’ve had this pufferfish for three months now. It’s not the most interactive, but it’s healthy and stays in one area. The tank is well-maintained and the water parameters are stable. It doesn’t eat the corals, which is a relief. A bit of caution needed with other fish due to its semi-aggressive nature.

The fish arrived healthy and has been thriving. It’s a good fit for a reef tank with proper water conditions. It doesn’t cause any disturbances to the coral growth. I appreciate the clear information on care requirements. Would recommend to experienced reef keepers.
