Care at a glance

Species-specific aquarium care

  • Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 1.6 in / 4 cm).
  • Water: Freshwater.
  • Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
  • Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.

Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.

Care guide

Species care notes

  • Tank: a base of at least 24 × 12 in (roughly 14 US gallons); space needed is rated “modest tank”.
  • Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–82 °F, pH 5–7.5, 1–12 dGH.
  • Behaviour: in a pair; not a community fish.
  • Difficulty: Easy (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “This species requires a well-decorated aquarium with driftwood roots or branches plus plenty of aquatic plants, of which floating varieties can be used to provide additional shade.”
  • Diet: “Tetraodontids lack true teeth, the jawbone itself being modified into four fused toothlike structures.”
  • Tankmates: “Less aggressive than some members of the genus but nevertheless best maintained alone or alongside a group of peaceful, schooling cyprinids of a size large enough to escape predation but small enough that they offer no competition or threat.”

Group care guide

Pufferfish

Applies to most species in this group. Habitat: Pufferfish inhabit marine reefs and coastal waters, brackish estuaries and, in some lineages, freshwater rivers and lakes. Individual species can differ, so compare with the species numbers above and the linked sources.

Level 5 reflects giants in this list; smaller species may suit experienced aquarists. The water range is for freshwater T. mbu; green-spotted puffers are listed at 75–82°F and are not interchangeable with mbu or marine species. No family-wide salinity is safe. Obtain adult-size and facility assessments for Arothron stellatus and other giants; do not use the toby tank size. These sources do not establish species-specific settings for Sphoeroides testudineus. Puffers can contain tetrodotoxin capable of fatal poisoning if eaten: never consume them or let pets eat them. Dental intervention belongs with a fish veterinarian.

Housing & setup

  • Identify species and salinity needs before setup: Tetraodon mbu needs freshwater, Arothron and Canthigaster need marine systems, and green-spotted puffers need a separate salinity plan.
  • For adult T. mbu, the cited profile specifies about 240 × 90 × 90 cm (96 × 36 × 36 in), approximately 1,944 litres.
  • Marine Canthigaster require around 150 litres; Arothron meleagris require an absolute minimum around 500 litres, preferably twice that; giant species require larger facilities.
  • Provide strong biological filtration and regular waste removal; large marine puffers also require effective mechanical filtration and protein skimming.
  • Provide rocks, caves and open swimming room, and protect cables and breakable equipment from their beaks.

Diet

  • Snails and hard-shelled molluscs such as mussels or cockles for shell-crushing species.
  • Shell-on crustaceans or crab legs sized to the fish.
  • For Canthigaster, small portions of chopped prawn, frozen Mysis and algal foods.

Sources 899900901902903904

Social life

  • Keep T. mbu alone: it can severely injure other fish and is aggressive to conspecifics. Marine tobies commonly nip trailing fins; puffers can consume aquarium invertebrates. Assess compatibility by species and individual.

Sources 899900901902903904

Handling

  • Never deliberately induce inflation.
  • Keep fingers and vulnerable equipment away from the beak.

Sources 899900901902903904

Health watch

  • Overgrown teeth interfering with feeding.
  • Overfeeding and diet-related health problems.
  • Water-quality illness associated with heavy waste production.

Understanding the animal

This species is part of a group that hobbyists, aviculturists or zoos keep widely (Pufferfish), so it's included for completeness. It may be rare in captivity itself, or not kept at all. Use the group guide as a starting point and look for species-specific advice from experienced keepers.
No real photograph of this species is freely available yet. The only images we found were scientific illustrations or maps, so none is shown. It stays on the site because there is evidence it is kept (see “Kept in captivity?”), but it is rarely kept or rarely photographed. If you keep one and can share a photo, we would love to add it.
About this animal

About this animal

It is a tropical species known only from Sarawak, Malaysian Borneo, where it occurs at a depth range of 1 to 2 m (3 to 7 ft). It is found in large, fast-flowing streams with silty and sandy bottoms, leaf litter, and submerged logs.
