Apistogramma trifasciata, like most of the South American dwarf cichlids, inhabits the smaller waterways and the calm bends of the main courses, where visibility is poor – mostly clear water and rarely white water.
Another feature of its natural habitat is the bottom which is made up only of very fine sand. In fact, this dwarf cichlid over time has adapted to sift the substrate in search of food by collecting it with its mouth and expelling the inedible part from the gills.
In the aquarium Apistogramma trifasciata is moderately peaceful when compared with Apistogramma borelli, but certainly much more manageable than other species in which aggression is particularly marked such as Apistogramma cacatuoides, Apistogramma agassizii.
The dimorphism is very accentuated, the males are larger and slender, have a more vivid color and a greater extension of the fins, especially the pelvic and dorsal ones. The females are smaller (4cm TL), less colored and with shorter fins, the anal fin is usually blunt.
Apistogramma trifasciata males develop during the growth phase, a remarkable development of the 2-4 rays in the dorsal fin often with extensions of different lengths.
A longitudinal band starts from behind the eye and extends to the beginning of the caudal fin which is rounded.
On the other hand, a lateral spot is missing, the caudal spot and ventral bands, there is the typical black band that extends from the upper attachment of the pectoral fin to the belly up to the first ray of the anal fin.
Important to mention is that in Nature there are different populations with different morphologies.
