Social fish are fish that can share the aquarium with many other fish species. Social fish primarily consist of livebearers and schooling fish. Schooling fish, such as tetras, rasboras, and barbs, seek refuge in groups of their own kind. Dense plants will provide them security when isolated, but it is necessary to have at least 8-10 fish. Soft-leaved plants are often used for egg deposition, thus offering breeding opportunities.
