Tetraodon fluviatilis
A few species of Tetraodontidae, a marine family for the most part, live in brackish
water. The round-spotted puffer, the commonest, can become aggressive on reaching
adulthood. It feeds voraciously on small snails, but will also take live prey. It
appears that this puffer can be bred in captivity by using brackish water and keeping
the temperature above 26°C. Size: 7-10 cm.
