Discus fish size series#

This species of fish is not, in fact, a new species but rather one that has been a part of the aquarium trade for years under the name Tefé Discus. In the home aquarium, these fish can be highly challenging to keep due to their specific requirements for water conditions. Though they display a wide range of colors, the intensity of their coloration is often rather bland. This group of discus fishes displays a wide variety of colorations ranging from solid green to yellow-green to brown. The final sub-species of Common Discus is Symphysodon aequifasciatus aequifasciatus, or the green discus. In addition to their strict nutritional needs, Blue Discus require soft, acidic water similar to their native South American habitat. Like all discus, Blue Discus are largely carnivorous and require a varied diet of live, frozen and pellet foods. This sub-species of discus can be moderately challenging to keep in the home aquarium due to their nutritional needs and water quality requirements. Some variants like the Cobalt Blue Discus have a metallic sheen while others, like the Royal Blue Discus, display a mixture of bold colors like blue and yellow. The blue discus is easily recognized by the blue longitudinal stripes and dark banding that runs horizontally along the body. Symphysodon aequifasciatus haraldi, or the blue discus, generally exhibit a dark blue or purplish brown coloration on their bodies.

The brown discus, Symphysodon aequifasciatus axelrodi, was once one of the most popular types of discus fish because it can be easier to keep compared to other discus variants in the home aquarium. This group of discus can be divided into three sub-species based on coloration: brown, blue and green. Brown Discus, Symphysodon Aequifasciatus Axelrodi
