Common Names: Ceylon Puffer Also Known As: Green Puffer
Synonyms: Chelonodon fluviatilis Family: Tetraodontidae
Origin: Sri Lanka, Bangladesh, Borneo, and Mynamar Main Ecosystem: Estuary
Salinity: High End Brackish/Full Marine Temperament: Active fin nipper, will predate smaller fish and invertebrates.
PH: 7.8-8.4 Temperature: 76-84F (24-28C)
Maximum Size: 8 inches (20cm) Minimum Tank: 30 Gallons (US)
Activity: Hunter/Seeker Lifespan: 15
Gender: No sexual dimorphism Breeding: Largely unsuccessful in captive settings. Possibly due to their breeding habits.
Diet: Feed ghost shrimp, snails, bloodworms, krill, shell-on shrimp, crabs, clams, and mussels. Snails need to be fed at least once a week to prevent overgrowth of teeth. Varied diet is a must and any freeze dried or frozen foods should be presoaked in tank water and vitamins.
Care: The care of this fish is very similar to T. Nigroviridis. As such, they should only be introduced to a fully cycled aquarium matching the salinity they were being kept in previously. The salinity should slowly be raised to full marine conditions. (no more than .002 SG per week)
Notes: This species is rare in the aquarium trade. Many times the fish sold as T. Fluviatilis are simply a variant of the Green Spotted Puffer (T. Nigroviridis). A true Ceylon Puffer should look like a cross between the Figure Eight Puffer and the Green Spotted Puffer. This species, although agressive, is not as agressive as the T. nigroviridis. They also seem to be compatible with T. nigroviridis of similar size.
