The Porcipine Puffer fish is an excellent beginner species. Their golden-brown body and spines make it a firm favorite. It has a comical and playful character. Shy at first but will eventually come out and beg for food. It can be taught to feed from the owners' fingers. Keep them in fish only tanks (75g. +) with fish the same size or larger. They are prone to ich and some may need de-worming. Also refrain from provoking its ability to inflate, as air may become trapped in their ailmentary tract.

Porcupine Puffer Diet

Silversides, Shrimp, Krill. 1/3 of the diet must consist of foods designed for herbivores. Also needs tough foods such as clams to keep its teeth from over growing.


This particular species can grow upwards of 18"

Minimum Tank Suggestion


Ideal water parameters for Porcupine Puffer

Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
