Care notes
Bright green with bold black spots and white belly. Juveniles are freshwater; adults require true marine salinity (1.018–1.025 SG). One of the more aggressive puffers — usually best kept alone. Snails must be provided regularly for beak maintenance. Very active and inquisitive.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
