Family: Tetraodontidae Β· Pufferfish
Also known as: Scribbled Puffer, Mappa Puffer, Map Pufferfish
The Map Puffer is one of the largest and most impressively patterned pufferfish available in the marine aquarium trade. Its substantial body is adorned with an elaborate network of dark brown to black lines, swirls, and irregular markings on a light gray to white base, creating a pattern that resembles the contour lines of a topographic map. A prominent dark ring surrounds each eye, and the pattern extends across the entire body and fins. Each individual has a unique pattern, much like a fingerprint.
Growing to a formidable 26 inches in length, the Map Puffer is among the largest pufferfish species commonly encountered in the aquarium trade. In the wild, it inhabits coral reefs, lagoons, and reef slopes across the Indo-Pacific, feeding on sponges, algae, tunicates, and various hard-shelled invertebrates. Its massive beak-like teeth can generate tremendous crushing force, easily breaking through shells, coral, and even aquarium equipment.
Despite its imposing size, the Map Puffer is a relatively gentle giant with a docile personality. It quickly bonds with its keeper and displays the intelligence and interactivity that makes pufferfish such beloved aquarium pets. However, the sheer volume of space and filtration required to house this species puts it firmly in the realm of advanced hobbyists with very large systems of 250 gallons or more. It is emphatically not reef-safe and will consume any and all invertebrates. The Map Puffer is best suited for large fish-only systems where its personality and dramatic appearance can be fully appreciated.
Map Puffers are carnivores with powerful crushing jaws. In the wild, they feed on sponges, tunicates, algae, crustaceans, and mollusks. In captivity, offer frozen krill, shrimp, squid, clam, silversides, and high-quality marine pellets. Hard-shelled foods such as whole crabs, clams, and large snails are essential for dental maintenance. Feed two to three times daily with portions appropriate to their large size.
The Map Puffer is generally docile toward other large fish but may bully smaller or slower species. It will consume all invertebrates without exception. Best kept in very large fish-only systems with other robust, moderately aggressive species such as large tangs, groupers, triggerfish, and other puffers. Avoid housing with anything small enough to be considered prey or that could be damaged by its powerful jaws.
Check CompatibilityMap Puffers have not been bred in home aquariums. Their massive adult size and pelagic spawning habits make captive breeding impractical. Reproduction in the wild is poorly documented, and all specimens in the trade are wild-caught.
