Tetraodon nigroviridis is one of the pufferfish known as the green spotted puffer. It is found across South and Southeast Asia in coastal freshwater and brackish water habitats. Tetraodon nigroviridis reaches a maximum length of about 15 cm (5.9 in). In February 2009 it was successfully bred in captivity at University of Florida using a new variation of the ovarian lavage technique.
Adult Tetraodon nigroviridis are found in freshwater streams, rivers, and flood plains; young are found in brackish water. It is also found in mangrove forests. This is however disputed and the exact habitat of this fish is not yet fully known. Diet consists primarily of snails, but includes small invertebrates such as mollusks, crustaceans, and some plant material. 

Tetraodon nigroviridis is often confused with its similar looking relatives T. fluviatilis , and T. schoutedeni. It can be distinguished from these by its more rounded shape when compared to fluviatilis and lack of spines on its belly (present in schoutedeni).


体态较小,身体滚圆且臃肿,腹部涨大,一对突起的大眼睛非常有神,游动时显的比较笨拙,鱼体呈鲜艳的黄绿色,上面散布着黑色或绿色的斑点,外型憨厚,其模样十分可爱。游动时用胸鳍拨水,更为逗人。用渔网捞起时,空气会进入鱼鳔,鱼腹部膨胀的象一个球。成鱼体长15厘米。雌雄鉴别不详。
  此鱼较难饲养,最好在水族箱中加少许盐或对入比例为二分之一的人工海水,这样可以幼鱼长成成鱼后的体形较大些。饲养该鱼的水族箱里的滤水器不可加活性炭,应该放入过滤棉和珊瑚砂,否则会使PH值降低,使该鱼难以成活,饲养过程中喂食活饵、人工饲料均可。
