Taggstrålar i ryggfenan (totalt) : 15 - 16; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 7 - 8. Diagnosis: lower pharyngeal jaw robust, with a large, heart-shaped dentigerous plate, covered with numerous fine, regularly arrayed teeth; mouth squared and obtuse (Ref. 81260). Lips broad and fleshy; ventral margin of lower lip folded and fringed (Ref. 26738, 81260). Fine buccal dentition of slender, movably implanted, spatulate teeth, 25-45 in outer premaxillary row (Ref. 26738).
Smaller specimens primarily found between sunken pieces of trees near lake shore, while larger specimens are found at greater depth - between 3 and 8 m; feeds mainly on plants and small quantities of diatoms and insects (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260). Biparental species that constructs a nest at a depth between 1 and 5 m, usually on a muddy bottom; pit relatively large and normally surrounded by some smaller satellite pits; when threatened, females will often seek refuge in these pits while males tend to swim away to open water (Ref. 52307). Maximum size recorded is 8.7 cm TL (Ref. 5163).
