It is ordinary that the Tetradon nigroviridis, is confused with the Tetradon fluvialitis or Tetradon schoutedeni.

Pufferfish Freshwater is originating in India, Sri Lanka, Thailand, Cambodia, Vietnam, Malaysia, Indonesia and the Philippines. In these places we can find in coastal areas, deltas freshwater, mangroves, streams and areas flooded by rain.
A suitable size for freshwater pufferfish, It should be some 150 liters, wherein the temperature should be between 24 ° C and 28 ° C, pH 7.5 a 8.5 (digital pH meter). Although they are considered a species of freshwater, you should add some salt to the water, to be partially brackish. The aquarium has to have a sandy bottom, and well planted, with roots, trunks and spaces that will serve to shelter. They are quite active, so that should leave enough space, so they can swim freely. They need water to keep in good condition, for what we should do partial water we change every week, as well as remove all traces of food that the fish has not been completed.
On freedom his favorite food are snails, owed provide regularly, and seafood shell, to keep your teeth sharp. Other foods that we can provide are, prawns, prawns, insects, larvae, squid or octopus, into small pieces according to your mouth. What they do not usually accept meals are prepared, as flakes or granules, but if you accept some vegetables or failing, nibble plants aquarium. Must be careful not to over feed, as they are quite gluttonous.
Behavior and compatibility
In the aquarium, we should not have more than one freshwater pufferfish, because they are quite aggressive with others of the same species. It advised only have more than one (ideally several, to reduce tensions), when the aquarium is good sized and there is room enough for everyone. Nevertheless, there is no problem in keeping with other species, whenever seeking companions strongly built and active, fish weaker or slower, they bite the tail. Some tank mates can be some types of gobio and brackish water species. If you know, which like other Tetrodóntidos (blowfish yellow, for example), They recognize its owner and left to feed her hand, while they are rejecting those who do not know.
Reproduction is not easy, But not impossible. maybe the biggest challenge is in getting a couple, because due to the absence of sexual dimorphism, several specimens should be kept in the aquarium until a couple forme, clashes with the problems we know. To succeed in reproducing freshwater pufferfish, we must increasing the salinity of the water, until it becomes brackish. The aquarium should have flat surfaces of rocks, where the female deposited eggs, to be protected by the male. Once hatched, The eggs hatch in a period of about seven days. Once they born, fry remain protected by the male, It is making a hole in the substrate.
