Description: The Green puffer Tetraodon Fluviatilis has a claviform body with a very large head, eyes are spaced and independent and are part of a few fish that can close their eyes, no ventral fins, caudal peduncle used as swimming rollers, has small spine facing back and forth on the head and body. They have a mouth formed by the fusion of 2 teeth for a jaw (These are used to crush and shell out invertebrates, the favorite food from most Green puffers). Many parts of the body of ball fish contain a deadly neurotoxin, the Tetradotoxin, this is the same poison found in the notorious marine octopus to a blue ring Hapalochlaena lunulata. They can reach up to 28cm in adulthood.

Coloration: White belly and yellow / green back with brown or black round spots.

Behaviour: At a young age it is very peaceful as it becomes more aggressive in adulthood. By absorbing water or air, they acquire the typical ball shape of this type of fish.

Temperature: 22-28 °C. pH: 7,8-9,0.
Water hardness: Hard water 10-30°H
Tips for breeding: We recommend a well-planted tank, with hiding places, rocks and woods. It is not recommended to insert into community aquariums or tanks with other Tetraodontids, also considering the demand for space to live, it is advisable not to insert with species that have slow motion or long caudal fins (they always bite them).
Feed: Omnivorous but above all feeding on alive food such as snails or shellfish, also accepts frozen food.
Diffusion: South East Asia. India, Bangladesh, Sri Lanka, Myanmar, Thailand, Laos, Cambodia, Vietnam, Indonesia.
Swimming level: Medium-low part
Difficulty: Average
Reproduction: It can be reproduced in captivity, parents caring for parental care like Cichlids. The female lays eggs on a flat surface, and is protected from the male until they are hatched. The beetles survive for the first few weeks thanks to the yolk sac that gives them nourishment, but after this time we need to feed the little ones with Rotiferi and then nauplius of artemia salina, just hatched.
Extinguish risk: Not at risk of extinction.
