Morphologie | Morphométrie
Épines dorsales (Total): 16 - 17; Rayons mous dorsaux (Total): 9-11; Épines anales 3; Rayons mous anaux: 8 - 9. Diagnosis: differs from C. crassa and C. louna by having 1 complete scale row and 1 additional scale row with smaller dorso-ventrally compressed scales between upper lateral line and base of last dorsal spine (vs. 2 complete scale rows and 1 additional row of very small scales in-between); differs from C. crassa by a shallower body with only a minimal overlap, 32.2-40.5% SL vs. 40.4-48.4%; and from C. louna by a shorter last dorsal spine, 9.4-12.2% SL vs. 12.9-15.0%; all scales cycloid; 26-27 scales on horizontal line; 17-22 upper lateral line scales; 8-11 lower lateral line scales (Ref. 92878).
Found in swampy forested zones (Ref. 52307) in grass-bank as well as forest-bank habitats, during the dry as well as the wet season (Ref. 92878). Pair-bonding, open substratum spawner with both parents guarding their fry (Ref. 52307).
