The Green Spotted Puffer is a striking fish with vibrant green coloring and dark spots. After setting up the brackish water system as recommended, it adapted well and became active in the tank. Requires careful monitoring due to its aggressive nature, but it’s a rewarding long-term addition to a well-maintained aquarium.

We followed the salinity and pH guidelines from LiveAquaria and the fish has been healthy for over two years. It’s active and curious, though it does need space and a secure tank setup to avoid aggression toward other fish.

The fish looks beautiful with its green body and white underbelly. We’ve maintained the brackish water conditions consistently, and it has thrived. The only challenge is ensuring the tank is large enough to accommodate its size and behavior.
