The pufferfish arrived healthy and active. It has adapted well to the 75-gallon tank. No coral damage observed. Good for intermediate aquarists with proper space and hiding spots.
Adrian Thomson –
It’s a striking fish with a unique appearance. Needs a large tank and some hiding places. Feeding is straightforward with high-quality pellets.
Mary Arnold –
We’ve had this fish for three months now. It’s calm most of the time and doesn’t attack other fish. The tank setup is stable and the fish seems content.
