Blue Discus or Brown Discus - Symphyosodon haraldi

Blue Discus or Brown Discus Symphyosodon haraldi have a much more varied color pattern and can have a larger number of vertical bars (8 to 16) than the other two species of discus. Other common names they are known by include Common Discus, Gypsy, Semi Royal Blue, and Royal Blue. They are considered one of the most beautiful and hardiest of the discus.

The Blue Discus are very similar to the Brown Discus though a bit longer bodied while the brown is more rounded. These varieties have a darker almost purple brown body and nine vertical bars without a bold central bar. (All the pictures shown here are captive bred hybrids). They often have blue horizontal stripes on the head, dorsal and ventral fins. The face is a deeper brown.Some hybrid strains are called Cobalt Discus, Powder Blue Discus, and Sky Blue Discus. A real beauty is the Cobalt Blue Discus. It is almost entirely blue, sometimes with a metallic sheen. Other specialties will sometimes have blood red spots on the dorsal fins.

Brown Discus varieties originate in the lower Amazon region in Brazil. They were regularly kept for a long time, however they are not as colorful as other varieties and are now less available.They have light to dark brown bodies (sometimes reddish), nine vertical bars (without the bold central bar), irregular streaks on the upper and lower fin areas, and yellowish coloring at the base of the dorsal fin, around the eye, and on the snout. They reach a length of about 5 " (13 cm). Redder body colors are sometimes enhanced by adding such things as prawn eggs to their diet, or by adding chemicals to their water. This enhancement is not permanent and will fade in a couple of weeks. They are not as colorful as the Green Discus or the hybrids.
