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.

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.
