Care and feeding: The Spotted Green Puffers are omnivores, though a large part of their diet is meaty foods. In their natural environment they will eat various invertebrates, crustaceans and mollusks, but they also eat some vegetation.They are not difficult to feed as they will usually eat a variety of flake, frozen, and live foods including shrimp, ghost shrimp (gut-loaded), bloodworms, freeze-dried krill, crabs, brine shrimp, and snails.
Puffers have strong teeth that grow throughout their lives, so are prone to overgrown teeth. Offer hard shelled live food often to keep the teeth worn down. Feeding snails daily will help to wear down the teeth. If the teeth get too long, they will be unable to eat, requiring the owner to clip the teeth.
Since puffers do not have gill covers or scales, they are thought to be more susceptible to diseases, nitrite, nitrate and ammonia levels. Like all puffers, this puffer is not a good fish to cycle an aquarium with. Also because they usually don't eat all of their food (messy eaters!), these fish will usually put more load on the aquarium filtration requiring more frequent water changes and better maintenance in general. A generous weekly water change of 30% to 50% is the standard recommendation for a puffer aquarium.
A 20 gallon aquarium mightwork well for this puffer, however if you want to be on the safe side, a well planted 50 - 60 gallon aquarium is better. Provide plenty of plants and rockwork for retreats as well as open areas for swimming. This puffer fish is a freshwater to brackish species and adding aquarium salt is suggested. But like many of the brackish species, the Spotted Green Puffer can be acclimated to hard, alkaline fresh water or it can be acclimated to a saltwater environment.
