Nope, it is the humpback, or black river puffer (t palembangensis). A FW puffer, not very active except when food's around. It is peaceful, not very agressive, easy-to-keep, interesting species that can be kept w/others of the same type (t suvattii) and/or fishes of other species that can look after themselves (e.g. large armoured catfishes). Spawns in captivity (a friend in Singapore is enjoying that).
