Looks how to spot one

Armoured catfish (bony plates, no scales)

A small, rounded catfish clad in bony plates, with short barbels for sifting sand. The body is off-white to soft pinkish-orange with a faint green sheen, set off by a black mask around each eye, a black patch on the dorsal fin and a black spot at the base of the tail, a pattern that recalls a giant panda. Females are a little larger and rounder.13

Coloursoff-white to pinkish-orangeblack eye patchesblack dorsal fin patchblack tail-base spot13

Personality what they are like

Exceptionally gentle and sociable. Pandas are shy alone but become confident, active and fun to watch in a group, rooting through the sand side by side.31

Daily activity how busy a day looks

Busy bottom foragers that also dart to the surface now and then to gulp air, so the surface must stay reachable. Open sandy areas let them sift for food naturally.342

Grooming and care the hands-on bits

Water: about 22 to 25 C (sources span 20 to 25 C as the preferred range), pH 6.0 to 7.4 per Seriously Fish (FishBase 6.0 to 8.0), hardness 1 to 12 dGH. Prefers slightly cooler, soft water. Keep the sand clean with regular partial water changes because they spend their lives on the bottom.321

Home where they are happiest

A tank of at least 45 x 30 x 30 cm (about 41 litres) for a small group, with fine smooth sand, some cover such as plants, wood or leaf litter, and gentle to moderate flow.3

Food basics what goes in the bowl

Omnivorous and easy to feed: a good sinking pellet or tablet as the staple, plus small live or frozen foods such as daphnia, brine shrimp or bloodworm.3

Company who they like around

A schooling fish that should never be kept alone; Seriously Fish advises groups, and Wikipedia suggests eight or more. Good with small, peaceful community fish.31

The story where it all began

Randolph H. Richards first collected the species in 1968, and Han Nijssen and Isaäc Isbrücker described it in 1971, naming it for its panda-like eye patches. It was very expensive when it reached the hobby in the late 1970s, but large-scale farming has since made it one of the most familiar corydoras.13

Fun facts for the dinner table

  1. 1

    Its name comes from the black eye patches that resemble those of a giant panda.1

  2. 2

    Like its relatives it can breathe air: it darts up, gulps at the surface and absorbs oxygen through its gut.4

  3. 3

    When first imported in the late 1970s it was wildly expensive; captive breeding has since made it affordable.3

  4. 4

    Eggs hatch in about three to four days at 22 C, and young fish gain their adult pattern after 10 to 12 weeks.1

  5. 5

    The new genus name Hoplisoma means 'armoured body', referring to the bony plates on its sides.5

The care rhythm a typical week and year

Owner questions the things everyone asks

How often should I feed my Panda Corydoras?

Furry Diary's starting plan is to feed small amounts once or twice a day. They are omnivorous and easy to please with sinking pellets or tablets as a staple.3 Pet Wiki plan

What does a Panda Corydoras eat, and what should it never eat?

They enjoy a good sinking pellet or tablet as a staple, plus small live or frozen foods like daphnia, brine shrimp or bloodworm. Avoid any floating foods that they cannot reach at the bottom.3

How much space does a Panda Corydoras need?

A tank of at least 45 x 30 x 30 cm (about 41 litres) is recommended for a small group. They need open sandy areas to sift for food naturally.3

What temperature, light or water does a Panda Corydoras need?

They prefer water around 22 to 25°C, with a pH of 6.0 to 7.4 and soft hardness of 1 to 12 dGH. Gentle to moderate flow and a reachable surface are important.321

How often should I clean a Panda Corydoras's home?

Furry Diary's starting plan suggests a weekly water change of about 25%, along with weekly glass cleaning and water testing. Rinse the filter monthly in old tank water. Pet Wiki plan

Can a Panda Corydoras live with others?

Yes, they are schooling fish that should be kept in groups of eight or more, and they get along well with small, peaceful community fish. They are shy alone but confident in a group.31

How long does a Panda Corydoras live?

Their lifespan varies depending on care and environment. For specific longevity information, it is best to ask a good breeder or an exotic-pet vet.

Can I handle a Panda Corydoras?

It is best not to handle them as they are delicate fish with bony plates and no scales. They are happiest when left to forage and swim in their tank.13
