Gold line corys, also known as Corydoras sp. CW010, are a small species of freshwater catfish that are native to the Amazon Basin in South America. They have a bright yellow-gold coloration on their bodies and are popular in the aquarium hobby for their active and social behavior.

Gold line corys have specific requirements when it comes to their environment. They prefer a slightly acidic pH level between 6.0 and 7.0 and a temperature range of 72-78°F (22-26°C). It's important to maintain these conditions in order to keep the fish healthy and happy.

In terms of behavior, gold line corys are social and should be kept in groups of at least six individuals. They are bottom-dwelling fish and enjoy having plenty of hiding places, such as caves or plants, to rest and explore.

Gold line corys are also known for their scavenging abilities and will eat leftover food and other debris on the aquarium floor. They are peaceful and can be kept with other non-aggressive species, such as small tetras or rasboras.

Overall, gold line corys are a great addition to any community aquarium with the proper setup and care.
