Hoplisoma panda

The specific name is an allusion to the appearance of the fish, which possesses large black patches surrounding the eyes, reminiscent of those found on the giant panda.

Corydoras panda has an off-white to pinkish-orange ground colour, and when observed under certain lighting conditions, a faint greenish iridescence is present upon the flanks and the operculum.

The pectoral fins are positioned immediately behind the operculum, and are usually oriented horizontally when the fish is at rest, extended in a manner similar to the wings of an aeroplane.

The lines of demarcation between individual scutes can be seen upon close examination of this and almost all other Callichthyid fishes, and in the case of some specimens of this species, are highlighted by additional black pigment.

Corydoras panda inhabits clear river waters that are relatively fast-flowing, well-oxygenated, and flowing over substrates that may comprise soft sand or fine gravel.

The native waters of Corydoras panda are consequently mineral-deficient, with a neutral to slightly acid pH, and replication of such conditions in captivity are recommended for successful maintenance.

Corydoras panda has a preference for cooler than normal waters when compared to many other popular tropical fish species due to their natural habitat.

Despite this, the species remains highly popular with aquarists, upon account of the appearance of the fish, and its lively, vivacious behaviour in a well-planned aquarium setting.

A minimum of eight individuals should be housed in the same aquarium, and if space permits, this number should be revised upwards, as the fish exhibits a very definite preference for grouping together with others of its species.

The aquarist is advised, however, that the traditional use of Corydoras catfishes as putative 'scavengers' in an aquarium setting will be detrimental to the well-being of this species—it requires high quality foods for long-term maintenance, and a varied diet.

Ideally, the fish should be given live foods at least intermittently, and will dine enthusiastically upon such items as Bloodworms (larvae of Chironomus midges), Daphnia, cultivated Brine Shrimp (Atermia salina), and Tubifex worms.

The last, however, should be cultivated in order to minimise the risk of introducing pathogenic organisms to the aquarium, as Tubifex live in unsanitary conditions in the wild.

In the wild, the appearance of new water courtesy of the rains is followed by an increase in the populations of assorted food organisms, and feeding upon these conditions the fishes for breeding.

When seen from above, the fish form a 'T' shape when conjoined thus, hence the term 'T position' has become conventional in aquarium circles when describing the breeding of Corydoras catfishes.
