DRAGON PUFFER (Tetraodon palembangensis) 4"

Unsuitable for the community tank due to its piscivorous nature. It can sometimes be kept with similarly sized or larger, active species such as bigger characins or cyprinids, but the risk is always there.

Surprisingly, while best kept as a single specimen, it’s not especially hostile towards its own kind and several can be maintained in a large tank as long as plenty of hiding places and visual barriers are provided. Some squabbles will inevitably occur, so do keep a close eye on proceedings if you decide on a group.
