Lillian Murray –
The pufferfish arrived healthy and active. It has been in my 75-gallon tank for three months and is adjusting well. I’ve added larger fish that can handle its occasional aggression. It’s a striking addition to the tank with its dark coloration and spots.
David Lee –
I was cautious about keeping a semi-aggressive species. The fish is active and curious, and it’s not causing any issues with the other fish. It’s a good fit for a well-maintained tank with proper space and hiding spots.

The fish is not as docile as expected. I had to remove a small shrimp that was too close to it. It’s a bold species and needs a tank with enough room and compatible tank mates.
