Looks how to spot one

Small sharpnose (toby) puffer that can inflate

A white body with four bold black saddles over the back, a blue-grey head and blue-grey speckles. The fins and tail have yellow tints, and a small rainbow streak sits behind each eye.2

Colourswhiteblackblue-greyyellow2

Personality what they are like

Semi-aggressive but curious. It is usually fine with other small fish, though it may nip at shrimps and clams.34

Daily activity how busy a day looks

Active in daytime, moving with fine control of its pectoral fins, even backwards.23

Grooming and care the hands-on bits

Rated easy care. Best in a fish-only tank or a reef with caution. When moving it, use a water-filled container rather than a net so it cannot gulp air.34

Home where they are happiest

A tank of at least 30 US gallons (about 115 L). Saltwater at about 23 to 26 °C (74 to 78 °F), pH 8.1 to 8.4, specific gravity 1.020 to 1.026. Wild fish live among coral heads and rocks of lagoon and seaward reefs at 1 to 55 m.341

Food basics what goes in the bowl

Feed meaty marine foods such as flakes, pellets, brine and mysis shrimp, and chopped seafood, plus shelled foods like clams and mussels. Wild fish graze algae and also eat tunicates and small invertebrates.341

Company who they like around

In the wild a territorial male keeps a harem of several females. In aquariums it is usually kept singly.21

The story where it all began

Pieter Bleeker described the species in 1853. It is named after the Dutch naturalist François Valentijn, who lived from 1666 to 1727.21

    It can puff itself up to three or four times its normal size.2

  3. 3

    Spawning happens in daylight, roughly between 8 am and 3:30 pm, all year round.2

    It is named after the Dutch naturalist François Valentijn.2
