Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 7 - 8; Mjukstrålar i ryggfenan (totalt): 14-16; Taggstrålar i analfenan 2; Mjukstrålar i analfenan: 6 - 8. This species is distinguished from all other cichlids by having only two (vs. three or more) anal spines; differs from B. opercularis by lacking anguloarticular lateralis canal; 3 or 4 (vs. 5) skin openings and 2 or 3 (vs. 4) canal fragments representing the dentary lateralis canal; dorsal fin with slightly prolonged anterior spines and lappets; modal dorsal fin count VII.15 (vs. VIII.14); and 6 (vs. 5) dark spots along the middle of the side (Ref. 86446).

Biologi     Ordlista (t.ex. epibenthic)

The type locality was a shallow laguna about 25 m wide, with transparent water, vegetation resembling needlegrass; water temperature 34°C; associated with another cichlid species, Crenicara filamentosum, the dominant species at the locality (Ref. 86446).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Eggs are deposited at the ceiling of a cave; the female tends to eggs and yolk-sac larvae; both parents care for the free-swimming young (Ref. 42051).
