Added a Sharpnose Toby to my 55-gallon reef tank. It’s active and curious, and hasn’t shown aggression toward other fish. The fish adapts well to the environment and stays healthy after a few weeks. Good choice for intermediate reef keepers.
Sonia Brown –
The pufferfish is lively and fits well in my tank. I noticed it avoids direct contact with corals, which is reassuring. It’s a bit semi-aggressive, so I keep it in a larger tank with plenty of space.

I’ve kept this species for over three months. It’s active, colorful, and doesn’t cause issues with the reef. The size is appropriate for a 40-gallon tank. A solid addition to a balanced reef setup.
