Bannertail Cory, Flagtail Cory, Halestribet Pansermalle (Denmark), Mrs Schwartz's Cory, Panzerwels (Germany) - Corydoras robineae   Burgess, 1983

The common name of this unusually patterned species comes from Mrs Robine Schwartz, wife of the late, great Brazilian fish exporter who gave his name to C. schwartzi. Mrs Schwartz and her son Adolf (yes, as in C. adolfoi) continue to run the fish exporting business Mr Schwartz began.

The fish is relatively new to the hobby, being described in 1983. It is unusual in being the only currently known Corydoras that possesses a "flag tail". There is another callichthyid (Dianema urostriatum) that also has this striking colouration. Furthermore, both these fish have an apparently natural habit of "hovering" in the middle of the water column as opposed to the normal bottom dwelling associated with most Callichthyids.

The only known species of Corydoras with a black and white horizontally striped ''flag tail''.
Sexing Mature females are plumper and the males are quite slim for adult Corydoras.

Feeding Sinking catfish pellets and bloodworm.
Furniture Needs a rounded substrate or sand. This species is especially prone to barbel loss at the hands of inept water management / inappropriate substrate.
Compatibility Peaceful, keep in groups of 3 or more.
Suggested Tankmates Most small community fish. Tetras and dwarf cichlids are ideal.
Breeding Until recently was one of the mystery corydoras that has yet to spawn in the aquarium. Keep in pairs, or no more than 3 males to 1 female. Condition them at 77F and then drop the temp. to 65F with a large water change. They will not spawn above 75F. Spawning has been attributed to feeding a diet of live tubifex worms. Water should be surprisingly hard for Corydoras, (11.3 dGH) and just alkaline (pH of 7.1 - 7.2). A bare aquarium with a few plants is all that is required, although the plants are for refuge, no reports exist of this species spawning on vegetation. Actual spawning is a mystery; it has always occurred at night. Eggs will hatch after 4-5 days, and the water temperature can be raised to 79F during this period. Initially chopped whiteworm appear to be the best first food, but the fry are quick growers and can soon be moved onto adult food.
Breeding Reports There is but a single breeding report, read it here.
