  • Size: 2,5-3 cm
  • Biotope: Found in slow-flowing, heavily-vegetated waters.
  • Social behavior: Males can be very aggressive and territorial, and they can even kill each other. Not recommended for the community tank, as they often nip the fins of long-finned fish, and they are also tiny for most tankmates. It is best kept in a single species set-up.
  • Diet: Carnivorous; Snails, shellfish and worms are accepted. They eat frozen foods as well, but dried foods are usually not accepted.
  • Breeding: Quite hard
  • Tank: Minimum 20 litres

Description: Carinotetraodon travancoricus has a golden brown base color with a whitish belly. There are greenish-blue or black markings on the body. Their eyes are blue. Like most puffers it's very sensitive to bad water conditions like nitrates and ammonia, so regular partial water changes are essential. Their teeth grow continuously and may become a problem, so hard shelled foods such as shellfish and snail diet can help to grind their teeth down. Interestingly they usually bite the snail and suck the meat out instead of crushing the shell. Puffers can inflate their stomachs with water or air, and become 2 or 3 times their normal size so can easily scare away many potential predators. When first introduced to a new environment they usually swmin around with tail curled in, and this is a defensive sign. Once they settle in the tank they will uncurl their tail.

Young fish are difficult to sex, but mature males are smaller with a dark line running down the length of their white belly and have closely-arranged lines just behind their eye, which are look like wrinkles. Females are more rounded and a little bit larger than males. The Dwarf Puffer is one of the few puffers that can be bred in an aquarium. Most breeders spawn them in pairs or in a harem (1 male and 2-3 females). A small breeding aquarium with a sponge-filter is enough. Plant the tank densely with fine-leaved plants like Java moss. During breeding the color and patterning of the male intensify a little and he starts to display to the female while circles around her. During courtship the male pursue the female vigorously and often nip or bite her. A successful chase usually ends in the vegetation, where the female release her eggs and the male fertilize them. The near-transparent eggs are only 1 mm in diameter and their number is very low, usually around 10. The eggs or the parents should be removed from the tank. The eggs hatch in 5 days and the fry become free-swimming in another 2 or 3 days. The fry can be fed with small live foods, such as brine shrimp nauplii.
