Common Name
Red Shoulder Macmasteri
Origin and Habitat
Apistogramma macmasteri comes from the Meta River basin in Colombia, a warm lowland tributary of the Orinoco. In the wild they inhabit slow-moving tributaries, backwaters, and flooded forest edges with soft, shallow water. The substrate is typically fine sand covered in leaf litter, fallen branches, and tangled roots. Water is usually tea-colored from tannins, with plenty of shaded pockets and gentle flow.
The Red Shoulder morph originates from naturally occurring color variants in this region that have been selectively line-bred in captivity.

The pair is active and colorful, showing natural red shoulder patterns. They adapt well to a well-maintained tank with soft water and driftwood. Easy to care for once the environment is set up properly.

Great for beginners interested in dwarf cichlids. The fish are peaceful and stay in groups without aggression. I added leaf litter and fine sand, which matches their natural habitat.
Brian Howard –
The coloration is vibrant and stands out in the tank. They are active during the day and rest at night. Water parameters were stable after a few weeks of adjustment.
