Melanotaenia australis is one of the more popular Australian rainbowfish in the hobby, and it's not hard to see why! With bold colours, sharp stripes, and a high activity level, th ey bring lots of life to mid-sized or larger community tanks. Like all rainbowfish, they are best kept in groups; a trio or more is strongly recommended. These are juveniles around 2-2.5" long. Show more
