The fish arrived healthy and active. It has adapted well to the 125-gallon tank after a few weeks. I’ve noticed it’s more active during the day and spends time near the tank walls. It’s not aggressive toward other fish, though it does occasionally chase smaller species. Overall, a good addition to a larger marine setup.
Yvonne Paterson –
We’ve had this pufferfish for about two months now. It’s not overly aggressive, and it seems to be adjusting well. The tank size is sufficient, and we’ve avoided keeping it with small, fast-moving fish. It’s a solid choice for intermediate aquarists with a large tank.

The fish looks healthy and has been active since arrival. I’m cautious about its behavior around smaller fish. It doesn’t attack them directly, but it does show interest. I’d recommend a spacious tank and careful selection of tankmates.
