Arothron reticularis

(Bloch & Schneider, 1801)

Reticulated Pufferfish

Range: Indo-West Pacific Ocean: India eastward through Indonesia to New Guinea north to Southern Japan and south to northern Australia.

Size: 18 inches (45 cm)

Natural Environment: Inhabits estuaries and protected muddy bays and usually found at depths between 3 to 85 feet (1 - 25 m) where it feeds on benthic invertebrate.

General Husbandry: Occasionally seen in the trade, with a tan body with numerous white dots and lines, some circling the eyes. Lacks pelvic fins, but uses the pectoral fins for movement.

Best maintained in fish-only aquariums with wide-open swimming areas, peaceful tankmates, and tankmates too large to be eaten. Provide a large cave to hide in when needed.

Should not be housed with aggressive or fin-nipping fishes, such as groupers, dottybacks, triggerfishes or angelfishes, as this is a slow moving species.

Requires a varied diet, i.e., chunky chopped fish or shrimp flesh, krill, clams, squid, and/or carnivore frozen foods, along with some vegetable matter. Leave the hard shells on shrimp that are fed, as this may help wear down its teeth. Should have numerous daily feedings.

Taxonomy:

Order: Tetraodontiformes

Suborder: Tetraodontoidei

Family: Tetraodontidae

Subfamily: Tetraodontinae

Genus: Arothron

FYI: Will eat smaller fishes, ornamental shrimp, crabs, snails, urchins, sea stars, sponges, clams including tridacnid clams, and tubeworms.

Will nip the fins of slow moving tankmates.

May graze upon coralline algae and eat stony corals.

When threatened, will puff up by taking in air and water and become balloon-like to deter predators.

The bodies of Pufferfish are covered in a toxic mucus (tetrodotoxin), a powerful poison to ward off would-be predators.

If the skin or flesh is consumed by humans, it can be fatal.

Probably will need to be dewormed and have its teeth filed to prevent overgrowth.
