Issue
See the notes above under C. arnoldi. This species appears more slender and it seems to inhabit more blackwater streams. Nothing has been noted about its breeding behavior. See Planquette, Keith and Le Bail, 1996:178 for its occurrence in French Guyana.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
South America: coastal rivers of the Guianas and Amapa in Brazil.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 5.7 cm TL male/unsexed; (Ref. 116983)
Lives in groups at the surface of small creeks with clear waters. Also found in ponds where it is found together with Rivulus (Ref. 27188). Feeds on Ephemeroptera larvae and ants. The spawned eggs are deposited on submerged leaves and are guarded by the males (Ref. 12225). During incubation, the male oxygenates the eggs (Ref. 27188).
