t has been a few months (October 2001) since my last Corydoras factsheet and I did not need a second reminder when I was sent a factsheet request to include this delightful little Cory in the factsheets archive.

Hoplisoma panda

This Corydoras ( now Hoplisoma panda) is actually a recent addition, in aquarium terms anyway, to the catfish hobby and was collected by Foersch and Hanrieder in a mountain brook at the side of the Rio Lullapichis (Ucayali/Peru) in 1969. It was not until 1971 that it was named in honour of the Giant Panda of China (Ailuropoda melanoleuca), which its markings resemble, by Nijssen & Isbrücker. The water conditions in this black water river was a pH of 7.7 and 3.1dGH. The temperature of the water ranged from 23.5°C (74.3°F) during the day and dropping down to 22.5°C (72°F) in the evening.

The panda cory created a great disturbance in the late 70's early 80's when it started to get a foothold in the hobby due to a breeding project carried out in Germany accumulating with this species arriving in the U.K. around about 1982. My abiding memory was of seeing this Hoplisoma (then Corydoras) at the British Aquarist Festival in Manchester of that year, with them priced on a stall at £40 each, needless to say I did not purchase any, I only admired them from afar!.

Of course nowadays this is a relatively inexpensive Hoplisoma to purchase as it has been bred often and proven to be hardy and not too hard to breed in the aquarium.

There is a Leucistic specimen that are believed to have been bred in Germany and are not albino but close to being leucistic i.e., pigment in the body with black eyes as seen below.

There is a clue in the collection data of this species in that it likes the water to be on the cooler side as it was first collected in the foothills of the Andes Mountains and as such the lower temperatures suits this Corydoras ideally, but in saying that the species in your tank has probably been far removed from the wild generation and would be used to temperatures in the high seventies, but I would be inclined to stick to the middle range of between 21°C-24°C (69°F-75°F.) A good pH range would be around the neutral mark (7) as they do not like the water to be too acidic.

This is a small inoffensive little Cory which will do better in a shoal, so buy at least six or more individuals. It would also be advisable not to keep rombustous species in with them such as Tiger Barbs and other fin nipping species as they would worry them to death with their constant harassment and would also deprive them of food as they would be inclined not to venture out for feeding, large Cichlids would also be a bad choice. A good community tank for them would house inoffensive tetras such as Neon's and other smaller characins, and if you would like other catfish any of the Ancistrus types would make good partners and of course other Corydoras/Hoplisoma or Aspidoras species. If you would like to breed Hoplisoma panda a species tank is the only way to go with a tank size of 18"x 12" x 12" being ideal for a group of six.

Remarks: Corydoras panda is placed in Lineage 9, the "short-snouted" species with the designated type species: C. punctatus. A revision in the future would constitute the resurrection of the genus name Hoplisoma (Agassiz, 1846).

Update: As of the latest revision (Dias et al 2024) Corydoras panda has now been placed in Lineage 9 and has the new genus name of Hoplisoma. Still found on some online sources as Corydoras panda.
