Mercury Discus
$32.00 – $75.00
Mercury is a fickle god, the winged messenger in charge of commerce, communication, and (for better or worse) luck.
Mercury also oversees the shady realm of trickery, as well as guides poor, unsuspecting souls through the depths of the fiery underworld.
The Mercury Discus fish, too, must navigate un-chartered waters. Only instead of the River Styx, the Mercury discus is trapped within the four glass walls of a home aquarium. Its translucent mother-of-pearl sheen makes it look ethereal, as if, like the ancient mythical god, it came from another world.
Or planet. Planet Mercury (the one that goes retrograde and makes packages late) is also named after the god Mercury, because of its close proximity to the sun. The scorching hot temperatures there make the planet move across the sky faster than any other, as quick as the Roman messenger-god.
While the Mercury discus fish doesn’t have wings, its fins propel it with precision, as it makes an epic splash in any underwater scene.

Natural Habitat for Discus
Discus are found in floodplain lakes and flooded forests of the lowland Amazon River basin and some of its tributaries, including the Rio Negro. These areas experience extreme changes in water level due to seasonal flooding. Discus tend to congregate near fallen trees, known as “galhadas”, along the shore. They prefer quiet water, and are rarely found in areas where there is strong current or wave action.
Discus Water Requirements
Discus prefer warm, soft, acidic water. pH should be between 6.0 and 7.0, with hardness between 1° and 4° dKH (18 to 70 ppm). Temperature should be kept between 82° and 89° F. Water conditions for both wild and hybrid discus are the same. While captive bred discus can be kept in dechlorinated tap water reverse osmosis or deionized water supplemented will ensure the the best conditions. Discus require pristine water quality, and depending on the filtration system being used, a weekly or bi-weekly water change of 10% to 25% is highly recommended. Don’t forget to treat tap water with conditioner before refilling your aquarium!
Housing Requirements for Discus
Discus grow to be quite large, and full sized discus will require an aquarium of 50 gallons or larger when they reach adult size. Tall aquariums are best, to accommodate their body shape. Current should be gentle, and décor if used at all should include large broadleaf plants and driftwood that is arranged vertically to simulate downed branches and trees. A few floating plants can also be added to provide shaded areas and cover. Substrate should be fine to medium grade and smooth surfaced, as discus like to forage along the bottom for food.
Discus Behavior/Compatibility
Discus are generally calm, peaceful fish, but as cichlids they can be aggressive toward one another, especially when attempting to pair off and spawn. Shy or submissive fish should be removed if they are unable to compete. Most serious hobbyists do not mix their discus with too many other species. However, suitable aquarium mates include cardinal tetras, neons, emperor and rummy nose tetras, as well as clown loaches and dwarf cichlids such as rams and Apistogramma species. All of these fish tolerate the high temperatures and low pH/hardness required by discus.
What do Discus Eat?
In nature discus eat a considerable amount of plant material and detritus, but also forage along the bottom looking for worms and small crustaceans. They are omnivores and will thrive on freeze dried black worms, beefheart, frozen blood worms, and a variety of pellet and flake food. Frozen and live foods may be fed as treats or to help induce spawning. For best results, rotate their diet daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.
Discus Breeding Level – Difficult
Captive bred discus will pair up and spawn relatively easily, but young, inexperienced parents may eat their eggs the first few times, particularly if other fish are present. After hatching the young feed on heavy body mucus secreted by the parents for a few days until they begin to free-swim. Parents will transfer the young back and forth several times a day.

Michael was great working with me to find what I was looking for in my discus and answering many questions I had prior to ordering. They came larger than I thought and full of color that I didn't expect. The shipping took longer than I would have liked and the fish were stressed but Michael ensured me to give them time and they have turned out great. Eating aggressively and grew in a weeks time. Michael was communicating with me daily on any question I had through acclimation and was very responsive.
Really happy with my discus from discus.com. Used airport - airport shipping and it did take longer than expected. In the future, would want to ensure the airport flight got them to me quicker or I would go with Fedex overnight to the house to ensure arrival by 10:30am. I was surprised how friendly these discus are. Years ago, when I kept discus they were very skittish. These beauties run up when I feed and eat right out of my hand. Thanks Michael, will add a new picture soon - they'e grown again :)
