Crossostoma stigmata

The Green Spotted Hillstream Loach is a unique aquarium fish known for its sucker-mouth adaptation, which helps it adhere to rocks in its native fast-flowing stream environments. They are peaceful but require specific conditions, such as high oxygen levels, strong water current, and ample algae for grazing. Due to their natural habitat, they are best suited for well-established, mature aquariums with rock and smooth sand substrates. These fish are sensitive to water quality, making regular maintenance vital. Additionally, they should be kept in groups to mimic social behaviors found in their natural habitat.
