The most colorful of all the Geophagus species is the Redhead Tapajos. Even smaller tetras can be tankmate of Geophagus Redhead Tapajos, as they are timid and usually do not bully other fishes. The smallest tank or aquarium size for Geophagus Redhead Tapajos is 3'-1.5'-1.5' (LBH) tank. Geophagus Redhead Tapajos needs clean little acidic water and some driftwoods. As the best substrate in a Redhead Tapajos tank you can use fine sand. They dig a lot in search of food and so need fine sand so that they do not harm their mouth. Good filtration is necessary as the substrate is disturbed very often.
