The Porcupine Pufferfish is a striking addition to my tank. It’s active and curious, though it does need a large tank. I’ve maintained stable water parameters and it’s adapted well to the diet I provide. A bit of caution is needed with coral placement, but overall a rewarding species.

I bought this fish for my 150-gallon tank. It’s not aggressive, but it does defend its space. I feed it a mix of frozen and flake food. It’s beautiful and adds a unique presence to the tank. Just make sure to avoid placing it near delicate corals.

After a few months, the fish has become a regular part of the tank. It’s active during the day and stays calm at night. I monitor water parameters closely, and it’s thriving. The care level is moderate, and the size is manageable in a large tank.
