About Geophagus brasiliensis (Quoy & Gaimard, 1824)
Males of this species can reach a length up to 25 cm (9.8 inches), while females only reach a bit more than half that size. In fact, males can grow just over a foot long, and females are generally a little smaller overall. The main body color ranges from pale light brown to dark blue or almost purple; their overall color changes with their mood and during mating sessions. This species, commonly called the pearl cichlid, has one dark spot that may be visible on its body, positioned toward the tail. It may also show several black bands running vertically from top to bottom down its body. The entire body is covered in markings made up of bright blue speckles, which shine brightly on healthy individuals. Their fins are red, may have blueish tones, and are tipped in black. These fin colors can also change, brighten, or fade depending on the fish's mood. When kept in a group, pearl cichlids usually pair up once they reach around 2–3 inches in length. At this stage, they become quite territorial, and keep other fish away from their breeding space.
