Bought this for my 75-gallon tank. The fish is active and colorful. It’s semi-aggressive, so I made sure to keep larger fish and avoid small shrimp. It’s grown steadily since I got it and looks healthy.

The pufferfish arrived in good condition. It’s not shy and swims around a lot. I’ve noticed it occasionally nips at smaller fish, so I’ve adjusted my tank setup to avoid vulnerable species.

Great addition to my tank. The yellow belly color is vibrant. I keep it with larger, hardy fish and it’s not causing any issues. It’s a bit territorial, but manageable with proper tank size.
