This was my male Dwarf Puffer. I believe it to be the Carinotetraodon imitator species because it has the iridescent lines around the eyes, a trait that the Carinotetraodon travancorius species does not seem to share.

A tiny species, usually an inch in total length, that originates from India. Often sold as a “Gold-Green Puffer”, “Dwarf Puffer”, “Indian Puffer”, “Pea Puffer”. One of the easiest species to visually tell genders apart. Look for a brown stripe on the belly, indicating a male. Note that not all males will be in display, so individuals with no stripe may be either female or male. Trios are best, allowing a selection process. Removing the third wheel” will help cut down on aggression, so having two tanks ready is key.

Plenty of Java Moss, other plants, rock work and other visual breaks in the tank help allow a community to survive. Despite their size, aggression towards other fish species and other puffer species is common, fin nipping and killing tank mates is not uncommon.

If you plan to breed this species, a sponge filter over the intake of the tank's filtration is recommended to prevent losing eggs or fry. Also, having a batch of rotifers, Daphnia, Baby Brine Shrimp, Grindal Worms other other tiny live foods is recommended. The fry are so tiny that feeding them is the hardest step towards clutch survival.

Also check out Ren's site, he has carefully documented his breeding experiences and created a lovely website.

Another link to examine is by Erwin Schramml, Erlebacher: comparison of the two species of Dwarf Puffer:

My experience has been extremely negative with this species. It seems that the individuals I can acquire locally have a parasite or bacteria that causes them to waste away. I have tried the de-worming medicines and other preventative measures to no avail. I have lost every last one I have tried to keep. They waste away and won;t eat. I will not keep this species any more. It is too heart breaking to watch and have no solution. Some areas must not have this problem, as other keepers have had success.
