The Porcupine Puffer, also known as the Porcupinefish, is a popular and interesting species of saltwater pufferfish that is native to the Indo-Pacific region. These fish are named for their ability to inflate their bodies, causing their spines to stand up and resemble a porcupine.
 
These saltwater fish require a larger tank size of at least 125 gallons with plenty of swimming space and hiding places. They are relatively hardy and can adapt to a variety of water conditions, but they prefer a stable environment with consistent water parameters and a salinity level between 1.020-1.025.
 
The Porcupine Puffer can grow up to 24 inches in length and has a relatively peaceful temperament, making it suitable for a community tank. However, they may become territorial towards other pufferfish and require plenty of space to swim and explore. They are also known for their ability to rearrange and even damage coral and other decor, so it's important to provide them with sturdy and well-anchored structures.
 
These fish are carnivores and require a diet of meaty foods such as shrimp, squid, and other seafood. They have strong jaws and teeth that are designed for cracking open shells, so it's important to provide them with food that will help wear down their teeth and prevent them from overgrowing.
