Origin

These beautiful fish come from flood plain lakes and rivers in the Amazon River basin of Brazil, Colombia, and Peru.


Sexing

These fish are not easy to sex visually while juvenile, but it is possible with mature fish. Males have pointed dorsal and anal fin ends, while females are more rounded.


Tank compatibility

Be cautious what fish you put with discus, as they will not tolerate most bacteria, which many fish such as Gouramis may produce. Careful selection is important, as larger fish such as the Angel, or Plecostomus may injure the discus, while smaller tankmates such as neon tetras, cardinal tetras, Cherry Barbs, etc., may be considered food. Entirely peaceful fish such as Corydoras spp. can make good tankmates with discus.


Diet

A high protein diet is a must. Discus are cautious when accepting new foods. Mysis shrimp and krill are excellent foods. It has been suggested that bloodworms only be fed to adult discus and only sparingly. The worm's rough carapace can cause constipation if overfed, which can cause mortality especially in juveniles. Caution should be taken with frozen brine shrimp, since as they dissolve, they tend to overly cloud the tank. Cloudy water from food may lead to sickness or death of your discus.


Feeding regime

Feed once or twice a day.


Environment specifics

This fish requires the highest standards of water quality, and high temperature, in the range of 32.2°C (90°F) . A large tank with still or slowly flowing water is required. Discus prefer a planted aquarium, but care must be taken to provide plants that can survive the high temperature of the water. Tanks for Discus generally need bi-weekly water changes of 20%-30% to ensure that water quality is kept pristine. The pH must be kept in check and stable. They must have a low pH and soft water with low levels (<20mg/l) of nitrate. Many keepers accomplish this through peat filtration.


Behaviour

If left in groups, ranging from 2-4, one dominant discus may self-proclaim itself as the leader, bullying the others. Having a number greater than five will usually thin out the chain of dominance. Discus will usually leave fish too big to eat alone.


Identification

Wild discus are normally murky brown in color, although some sort of color and/or pattern may be visible. Captive bred discus are, for the most part, exceptionally colorful, rivaling even some of the most beautiful marine fish. This is due to selective breeding. It has been said discus may be interbred several times before defects begin to show.
There is a huge array of various colours now created through selective breeding, see them here.
