Tetras & Rasboras for Freshwater Aquariums
Tetras are fish which have one of the widest varieties of color and size available in the fish keeping hobby. Tetras can be anywhere from 1 inch to 15 inches when fully grown, so it is very important to review the maximum adult size of each tetra before purchasing one or several for the home aquarium. Tetras are generally peaceful or semi-aggressive, and they make excellent fish for someone just beginning the fish keeping hobby. Many of these fish, such as neon tetras, are best kept in schools, giving the fish a great sense of security and keeps their stress to a minimum.
