Saltwater Fish
Porcupine Puffer.
One of the most expressive fish in the hobby, the porcupine puffer has big soulful eyes, a comical grin, and a body covered in spines that lie flat until it inflates. These hardy, long-lived marine puffers become genuine pets that beg for food and recognize their keeper. They need a large tank and a fish-only setup to thrive.

Good tank mates
Does best with other large, robust fish and should not be housed with small fish or invertebrates it may eat.
Good to know
When threatened it gulps water to inflate into a spiny ball, erecting the spines that give it its name.
