This pufferfish is a stunning addition to my 200-gallon tank. Its color patterns change beautifully over time and it’s very active, often hovering near the surface. I’ve noticed it interacts with food in a curious way, which is entertaining to watch. It’s not the easiest fish to keep, but the visual impact is worth it for experienced aquarists.

The fish arrived healthy and looks exactly as described. It’s semi-aggressive, so I made sure to keep it with larger, non-susceptible tank mates. The coloration is bold and stands out in the tank. I’m happy with the purchase and would recommend it to others with a large, well-maintained aquarium.

It’s a visually impressive fish, but I found it to be quite active and needs a lot of space. I’m still adjusting to its behavior, especially during feeding times. It’s not for beginners, and the tank size requirement is strict. Still, it’s a unique and eye-catching species.
