Porcupine Puffer

Porcupine Puffer

The Porcupine Puffer is one of the most well known marine fish by not only aquarists but individuals worldwide. Its body consists of many spikes which dress its entire body. Its actual body colour can vary greatly, from light grey to a variety tan colours, and usually have some dark patchy areas. Additionally, this puffer holds teeth that are formed into a beak that can be used to crush shellfish when eating. 

In order to home this messy eater, a 500 litre aquarium is required at an absolute minimum. Additionally, the system to this aquarium will need to have a effective protein skimmer and filtration. Furthermore, this fish will not be suitable for those reef tanks as it is known to nip at corals and clean up crew members. 

The Porcupine Puffer is able to suck in water and inflate its body by about 100% and force its spikes outward, when it feels threatened. It must also be notes that this fish has poisonous flesh, and if digested by another fish it will be extremely harmful to them. 

This puffer has to be offered a broad diet, including a range of meaty foods , such as clams, squid, prawns, and hard shellfish to help grind down their continuously growing teeth.

  1. My Puffer is intelligent, peaceful and has personality along with a hearty appetite. It recognizes the hand that feeds it. It will swim up to the glass when it sees me during the day and lets me know when it’s feeding time by hovering in one spot near the tank’s front surface looking directly at me. This is a great fish for a big tank with non-aggressive tank mates.

  2. First things first, this is our FAVORITE fish. They have so much personality, and are such a joy to watch. We currently have two in a 75-gallon reef tank. One is an adult and the other is a juvenile. They do not disturb any of the corals but they will eat some snails and hermit crabs occasionally if they aren’t fed on time. They are extremely hardy and happy. The little one even survived being stuck to the powerhead overnight. It did get sick and took about three weeks to recover, but now he’s back to normal and enjoys staring at us as much as we enjoy staring at him. The adult knows us and will let us pet him, and we hand feed both of them. I’ll say it again, we LOVE our Porcupine Puffers and they are such fun to have.

  3. I had a 8″ porcupine in my old fish only system a couple of years back. No fish will provide as much personality as the porcupine puffer does, it is literally like having a marine dog. It will notice your in the room and try and get your attention in the hope for some food, also as you lift up the lights and go to feed it they usually come up to the top and spit water at you, which is really fun to watch and experience. They will literally eat anything you feed them. Amazing fish!
