Cinaruco (south-western Venezuelan llanos) indicate that both species are mouthbrooders(HLF unpubl). Both species are among the most abundant in samples from lagoon, or to a lesser extent, channel habitats over bare sandy bottoms, although they can be abundant in structured habitats with submerged wood or rocks (Arrington, 2002).

Preliminary diet analyses indicate that, at least qualitatively, both species share a diet of benthic insect larvae dominated by chironomids (Diptera), trichopterans and ephemeropterans (HLF unpubl.). Given the great similarity of these species in overall morphology, color patterns, feeding modes, and probably reproductive behavior, it is remarkable that they seem to share the same habitats in an extensive manner.
