Introduction
This is the smallest of the pufferfish species. At least one distinct colour variation of C. travancoricus has been described, with blue spots. It is not yet known whether this is a separate species, subspecies, or regional variant. A distinct but very similar species was described in 1999[1] - Carinotetraodon imitator. This species has probably been imported under the same common names.

Tank Setup
A small species setup with some real or artificial plants for cover would be ideal.

Community Tips
Despite their small size, they may nip the fins of other fish.

Feeding Tips
Carnivorous: small live and frozen foods including snails, bloodworm, pieces of mussel and cockle.

Sexual Identification & Breeding
There are slight differences in the markings between sexes, but available details vary, and in some cases may not represent gender differences. However, males may show a brownish line along their stomach, from the 'throat' towards to the anal fin. Females are generally rounder in body shape. These differences will probably not be apparent when selecting juveniles.
These fish have been bred in aquaria, but few details are available.
