|Common name||Green Puffer, Topaz puffer, Ceylon puffer
(use of the name 'Green Spotted puffer' is best avoided to minimise confusion with T. nigriviridis)

|Size||Up to 8" (20cm), but often smaller in aquaria.|
|Origin||Asia: Bangledesh, India, Sri Lanka|
|Tank setup||A brackish tank, with rocks, bogwood or robust/plastic plants for cover.|
|Compatibility||May be aggressive to their own kind or other puffers. Keep alone or with other
larger brackish fish, such as monos and scats.|
|Water chemistry||Brackish, hard and alkaline.|
|Feeding||Live and frozen meaty foods: bloodworm, cockles and mussels, earthworms, snails|
|Breeding||Spawning occurs in brackish water. The eggs are laid on the substrate or a stone, and guarded
by the male. Hatching takes about a week.|
|Comments||This species can be kept in freshwater when young, but should be adapted to brackish water as it grows, for its long term health.
One of the more commonly encountered brackish puffers, it is often confused with T. nigroviridis
(a similar brackish species, also often known as the Spotted puffer) and T. schoutedeni (Spotted Congo puffer) - a freshwater species.
There are a number of regional variants, which show variation in the pattern of their markings.||
