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.

Scientific NameCorydoras robineae  Burgess, 1983
Common NamesBannertail Cory
Flagtail Cory, Halestribet Pansermalle (Denmark), Mrs Schwartz's Cory, Panzerwels (Germany)
Type LocalityRio Aiuana, s. trib. of the middle Rio Negro, Amazonas, Brazil.
PronunciationKory DOOR ass - ROBB i nay
EtymologyCory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. Named for Mrs Robine Schwartz.
Jump to next section Species Information
Size 70mm or 2.8" SL. Find near, nearer or same sized spp.
IdentificationCorydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

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

FeedingSinking catfish pellets and bloodworm.
FurnitureNeeds a rounded substrate or sand. This species is especially prone to barbel loss at the hands of inept water management / inappropriate substrate.
CompatibilityPeaceful, keep in groups of 3 or more.
Suggested TankmatesMost small community fish. Tetras and dwarf cichlids are ideal.
BreedingUntil 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.
