This is for one young adult show male.

Apistogramma macmasteri (Red‑Shouldered Gold Morph) is a vibrant dwarf cichlid prized for its golden body coloration accented by deep red shoulder markings and flowing fin extensions in males. In the home aquarium, it is a hardy and adaptable apistogramma, showing typical territorial behavior during breeding but remaining manageable and peaceful in a well‑structured tank with caves and visual barriers. This morph is especially appreciated for its bold courtship displays and attentive parental care. In nature, Apistogramma macmasteri originates from the Orinoco River basin of Colombia and Venezuela, where it inhabits slow‑moving, soft‑water streams and flooded areas rich in leaf litter and submerged wood.
