The Porcupine Puffer is equipped with spines, and also features jaws with two fused teeth, which looks similar to parrots. It is commonly referred as burr fish or balloon fish and is popular among aquarists. The Porcupine Puffer uses its strong jaws and teeth when feeding on hard-shelled invertebrates. It should be provided with a large aquarium, and should not be kept in a tank less than 65 gallons. The Porcupine Puffer needs alkaline conditions and water temperature between 75-82 degrees Fahrenheit. Once it is puffed up, its spines get erected and we advise you to handle it with care. The Porcupine Puffer produces a toxin, which is known as tetradotoxin, in the skin and viscera that makes it unpalatable to most piscivorous. The Porcupine Puffer acclimatizes quickly to an aquarium life, and needs lot of hiding places with rocks and crevices. The Porcupine Puffer is not at all considered reef-safe since it nips over the corals and can make them suffer by darting poison on them. It should be kept in a fish-only aquarium, and it is highly recommended not to add multiple inhabitants in the same tank. Also, acclimation time of one to two hours should be given to this fish. The Porcupine Puffer has a distinct feature to save itself from predation - by ingesting water into the ventral portion of its body, it blows up so it becomes difficult for the predators to ingest it.
