Joe McGrath –
Bought this pufferfish for my 40-gallon reef tank. It’s active and colorful, and hasn’t shown aggression toward other fish or corals. Adjusted water parameters slightly to match its needs. Very happy with the purchase.

The Pearl Toby is a striking addition to the tank. It’s semi-aggressive but doesn’t cause issues when kept with compatible species. Needs a stable environment and regular water changes.

Felt confident adding this fish after reading the care guidelines. It’s calm most of the time and blends well with the reef. Only needs occasional monitoring of water chemistry.
