This pufferfish is active and colorful. It has adapted well to my 55-gallon tank. I’ve noticed it doesn’t harm the corals, which is great for a semi-aggressive species. Feeding is straightforward with frozen brine shrimp. It’s a good addition to a reef setup.

The fish arrived healthy and looks vibrant. It’s not overly aggressive, and it spends time near the back wall. I’ve kept it with a few soft corals and no issues so far. Needs a stable environment, but overall a satisfying pet.

I’ve had this fish for three months now. It’s active, curious, and doesn’t cause stress to other tank inhabitants. The size is within the expected range, and it’s a great choice for intermediate reef keepers.
