Porcupine Pufferfish (Diodon holocanthus)
Max Size: 1 foot
Reef Compatible: No
Minimum Tank Size: 180 gallons
The Porcupine Puffer, also known as the Porcupinefish or Porcupine Pufferfish, displays a distinct appearance with spiny appendages covering most of its body. Its coloration can range from light gray to mottled tans, sometimes adorned with dark spots. This unique fish possesses a fused beak-like structure as its teeth. Despite lacking pelvic fins, the Porcupine Puffer has adapted to using its pectoral fins for movement.
For its habitat, a spacious 180-gallon or larger fish-only aquarium equipped with a good protein skimmer is recommended. It should be noted that this puffer can display aggression at times, potentially nipping the fins of tank mates and leaving circular marks. In a reef aquarium, it may consume invertebrates. Furthermore, when threatened or frightened, the Porcupine Puffer has the fascinating ability to inflate its body to nearly twice its normal size. Certain parts of its flesh are poisonous if ingested.
To meet its dietary requirements, the Porcupine Puffer needs a varied diet of meaty foods such as squid, krill, clams, and hard-shelled shrimp. These food items also help to wear down its continuously growing teeth.
