Lake Tebera Rainbowfish Melanotaenia herbertaxelrodi in the Dallas World Aquarium

This rainbowfish is native of the Lake Tebera basin in Papua New Guinea.  I have never seen rainbowfish of this species anywhere that approach the size and beauty of this group which I photographed at the Dallas World Aquarium in 2010.

Melanotaenia lacustris, Turquoise rainbowfish in the Dallas World Aquarium

When given good nutrition, a spacious aquarium and excellent care, the Turquoise rainbowfish can grow into a size and shape that is rarely seen in fish kept in the average aquarium.  I saw this stunning specimen during a visit to the Dallas World Aquarium in 2010.  This fish was just a tiny part of the many interesting things I saw there, nevertheless is small size, it is very impressive in its own right.
