Bought a tiny Valentin Toby for my 30-gallon reef tank. It’s active and curious, and hasn’t shown aggression toward other fish. The fish has grown steadily and looks healthy after two months. Easy to maintain with proper water parameters.

First time keeping a pufferfish. The tiny size makes it less intimidating. It’s semi-aggressive but not overly so. I’ve noticed it’s more active during the day and hides at night. Water quality is key, and I’ve been testing parameters weekly.

Perfect for intermediate reef keepers. The fish is colorful and stays calm in a well-established tank. I’ve had it for three months and it’s thriving. No issues with corals or tank mates so far.
