spinecheeks

Spinecheeks are a group of freshwater fish belonging to the genus Equidens. These fish are native to South and Central America, inhabiting a wide range of aquatic environments including rivers, streams, and lakes. The name "spinecheek" is derived from the distinctive spines located on the operculum, or gill cover, which are present in many species within the genus.

Equidens species are known for their varied appearances, with colors and patterns differing significantly between species. Many exhibit vibrant hues and intricate markings, making them popular in the aquarium hobby. They are generally robust fish, with a laterally compressed body shape. Their diet typically consists of insects, small invertebrates, and sometimes plant matter.

Reproduction in spinecheeks often involves parental care, with both parents guarding their eggs and fry. They are known to be territorial, especially during breeding periods. Several species are commonly kept as pets, requiring well-maintained aquariums with suitable water parameters and hiding places. Over 15 recognized species are currently included in the Equidens genus.
