General Description
Puffer fish, known for their ability to inflate their elastic stomachs with water or air, belong to the Tetraodontidae family. Among them, Tetraodon Cochinchinensis, commonly referred to as Fang's Puffer, can grow up to 7.0cm. These predatory fish, which encompass the deadly neurotoxin tetrodoxin in various body parts, are ambush predators with the defense mechanism of puffing up when threatened.
Aquarium Setup
For housing a Tetraodon Cochinchinensis, a minimum tank size of 40 liters is recommended. A heavily-planted environment with twisted roots and branches provides ample hiding spots, while floating plants help diffuse light. It's essential to maintain water conditions within a pH range of 6.5-7.8, with a temperature of 24-28°C and a water hardness of 8-15°dH (see table). Regular partial water changes are crucial to prevent deteriorating water quality.
Behaviour
This species exhibits aggressive and intolerant behavior, making it unsuitable for community tanks. Fang's Puffer can be cannibalistic and should be housed alone to avoid injuries. They are known to bite off chunks of other fish and can even rip them apart, displaying hostility towards their own kind as well.
Feeding and Diet
Tetraodon Cochinchinensis enjoys a diet consisting of shellfish, worms, and other meaty live or frozen foods. Regular feeding of snails and unshelled shellfish, like crab legs and mussels, is necessary to keep their teeth trimmed as they grow continuously. Failure to do so may lead to dental issues for the fish.
Reproduction & Dimorphism
Limited data is available on the reproduction of Tetraodon Cochinchinensis in captivity. However, it is noted that males may exhibit some form of brood care. Sexual dimorphism for this species remains unknown.
Habitat and Distribution
Found in freshwater bodies ranging from rivers to ponds, including some with brackish water, Tetraodon Cochinchinensis is native to Thailand, Cambodia, Laos, and Vietnam, where it thrives in both still and slow-moving waters.
