Topaz Puffer (Dichotomyctere fluviatilis)

The Topaz Puffer or Ceylon Puffer is a colorful brackish water species found throughout much of the Indo-Pacific, where it typically inhabits estuaries and lagoons. These fish originate in mangrove swamp habitat in Negombo Lagoon, Sri Lanka, where salinity generally ranges from 10 – 18ppt. A hardy, active, and outgoing species, this medium-growing pufferfish species will do well with similarly sized fast moving tankmates like Scats, Monos, or Chromides. Like most pufferfish, they can be prone to nip at tankmates so they should be monitored carefully, especially when first introduced.
