Jack Avery –
The Pearl Toby Pufferfish is a striking addition to my 30-gallon reef tank. It’s active but not overly aggressive and blends well with other fish. I’ve observed it interacting calmly with polyps and has not damaged any corals. A great choice for intermediate reef keepers.

This fish arrived healthy and has been thriving in my tank for three months. It’s semi-aggressive but doesn’t pose a threat to other inhabitants. I appreciate its vibrant color and active behavior. Only needs occasional monitoring during feeding.

I added this pufferfish to my reef tank after researching compatible species. It’s been peaceful and has not shown signs of aggression. The fish is colorful and adds visual interest without causing stress to other tank mates.
