Table of contents
Introduction
The Blue Neon Rasbora (Sundadanio axelrodi) is a stunningly vibrant species that can be a joy to watch in an aquarium setting. Despite their size, these fish are full of personality and make for an excellent addition to a peaceful community aquarium. However, they are not recommended for beginners due to their specific care requirements. To keep them happy and healthy, it is crucial to maintain their water parameters and environment carefully. The Blue Neon Rasbora boasts a dark blue upper body that shimmers with iridescence, which gradually transitions to a fiery red mid-lower body. The rest of the body is transparent, which only further emphasizes the electric blue hue. The males exhibit a black anal fin that will darken when they are dominant, although it can look peculiar and might be mistaken for fish waste. There are several colour variations available, including neon-copper, neon-blue, neon-green, and copper-clear. These variations add an extra layer of visual appeal to these already captivating fish..Neon Blue Rasbora Photos
