Duri dubur: 3. Aequidens is very similar to Geophagus but is differentiated by the number of spines on the anal fin and the lacks of a lobule on the first branchial arch found in Geophagus; live specimens olive green, with eight obscure transverse bands on the body; numerous bright bluish-green lines on the cheek; males are more colorful and grow bigger than females; males blue in color during the reproductive season (Ref. 26543).
Body shape (shape guide): fusiform / normal.
Adults inhabit turbid standing waters as well as clear free flowing streams (Ref. 11225). They feed on worms, crustaceans and insects (Ref. 7020). Reproduces in captivity (Ref. 26543). Both parents guard the eggs and larvae (Ref. 7020). Utilized to control mosquito larvae (Ref. 40602). Aquarium keeping: in pairs; minimum aquarium size 100 cm (Ref. 51539).
In captivity, both male and female clean a rock which will be the spawning area. Eggs are laid on the rock by the female and fertilized by the male. Both male and female guard the eggs, which hatch in 2 to 5 days, and continue to look after the fry for some weeks (Ref. 7020). In cases of danger, the male protects its young by placing them inside its mouth (Ref. 26543).
