Cory CW 032 has a name!

Like yet-described plecos and their L-numbers, there are a lot of corydoras without formal descriptions identified with a C-number. There is now one less C-number without a name. CW 032 has been formally described as Corydoras knaacki.

Corydoras knaacki

coryknaacki2.jpgCorydoras knaacki is described from tannin-rich, swampy drain basins of rio Madre de Dios, Peru.  Like other corys, C.knaacki is communal and will form schools.  Juveniles aggregate in much larger schools than adults, the latter being only found in smaller groups in deeper waters usually under shade.  The photo below is typical of where this species is found in the wild.


Its closest morphological kin is C. bondi, although C.knaacki is unique and easily distinguishable from its congenors. 

The photo to the right shows the development of color patterns for C.knaacki during its first six week, when its final form is established.  This fish was captive bred by the paper's second author, Hans-Georg Evers.

Corydoras knaacki is described in Neotropical Ichthyology.
