Food and feeding

Fang’s puffer requires plenty of live or frozen meaty foods. Cockles, mussels, and prawns are ideal. Supply then with a steady input of snails as the shells will help to keep their beaks trimmed down.


Asia; Fang’s puffers are found in Thailand and Vietnam.


There are no visible differences between the sexes.


Tetraodon cochinchinensis have been bred in the aquarium but it is a case of luck more than judgement. When fry are produced there is no parental care and they should be removed for their own safety.


The expected life span for Tetraodon cochinchinensis is 10 years.

Short description

Fang’s puffer is extremely aggressive to other tank mates. Best kept in a species tank and if you are keeping more than one specimen add plenty of plants and décor to break up the views so that they can establish their own territories. Because of their diet, they are high waste producers, it is best to over filter the water rather than let the quality drop.
