Many things are written on the maintenance of the discus, and can be read everything and its opposite on the sites internet and other media… Way of life of the discus, cohabitation, water quality, or food; This article has no claim to the 'divine truth' but to trace the outline of the maintenance King fish…
A gregarious lifestyle
First, I believe it is important to note that the discus is a gregarious fish that continues preferably in groups of 5 to 6 minimum individuals. Many start by purchasing 2 to 3 individuals; the reasons cited are frequently; "I prefer to slowly start to see" or "considering the price., I prefer to begin by 2/3 fishes" .
But it is in my view of the first classic error.(I have the same) The discus maintained in a group feels safe and is much better suited to its new environment. More aggressiveness is even annihilated; the dominant fish don't always 'traumatic' on the same fish…because our discus remains a "fat head" of cichlid.
Actually, Some will say ' I don't have that. " 2 or 3 Discus and all is well ! "and that's the charm to keep discus (like any other animal also) There are many factors in account. Sex ratio example; as a "' three discus group 2 males and 1 female will not have not the same behavior as a 'group' of 2 females and 1 male; It may evoke even size l’aquarium or even the implantation of its decoration. A couple formed may very well agree to two without problem. The important thing is to observe the behavior of fish.
Let's say that you put more luck on his side now a small group of individuals. Often adding an extra discus to effect of "calm" the warlike ardor of a discus too dominant.
The discus prefer to live in a group
The cohabitation in a discus aquarium
In a second time, I think it is interesting to mention the fish live in the side of the discus…
Indeed, should choose the future companions of discus, and always perform a quarantine for newcomers.
Overall, avoid the fishes strong or too much stirring nature. Customize your choice depending on the requirements of discus.
Think of the corydoras in selecting tolerant species high temperatures, some CHARACIDAE as classics cardinalis (Paracheirodon axelrodi) also agree; Similarly some loricaridés.
Many books evoke this topic as such «» The discus Crown "in the collection AQUALOG SPECIAL.
Our dear fish environment is also very important if not the most important. An imbalance between fish and its environment can cause problems (loss of appetite, Chicken fish, disorders respiratory etc etc …) or the appearance of diseases.

A good water quality: The basis of a good maintenance of the discus
Many discussions on this subject have been, and are still debate. But one thing is certain, the discus is a fish that physiologically requires a water little mineralized. Although certain strains are adapted to a waters more 'limestone '., one way that we are putting more luck on his side by offering to the discus an water little mineralized.
To properly control the water in the aquarium, equip yourself from reliable tests; drops or electronic test (for the pH and the conductivity). First, equip you test KH, GH, pH, nitrites and nitrates tests.
For a maintenance one tray KH between 2 and 4 should be with a RI between 4 and 7. of course, the pH should be between 6.5 and 7.; with a GH between 4 and 7. Naturally, the pH should be between 6.5 and 7.
The rate of nitrites must remain close to zero and below 25 mg/L nitrates. Same one temperature around the 28-30 degrees Celsius will be necessary.
How to get good quality of water for discus
There are 3 case of figures:
* We have the chance to inhabit a region or l’water is little mineralized low in nitrates.This water lacks major pollutants. 'Just' fully prepared with a good water conditioner (Will be Aqutan, JBL biotopol, TETRA aquasafe…)
* There is a water of good quality (no nitrates, phosphates etc…) but relatively limestone.Just ask analyses at the Town Hall. In this case a mixture of tap water (treated with a good conditioner) and (d)’water should be with a RI between 4 and 7. of course, the pH should be between 6.5 and 7.. The’water has a low content minerals. Thus by mixing a proportion (define) osmosis and d water’tap water; It gets the values that are to be.
* The’water flowing from tap a high nitrate content or other pollutant (phosphates, metals etc…) and in this case will not be used for anything. Should be used 100% of’water We are going to re-mineralize with a mineral salts specific. (for example, the mineral salts trademark PREIS, Will be or DENNERLE)
To ensure a good quality water to its fishes, It must also be regular in its aquarium maintenance and its water change. Of all properly sandboxed populated by discus having finished their growth; need to change 25 to 30% the minimum aquarium volume 1 twice a week using a Bell in sand.
The particular case : The injection of CO2 with the discus
TheES benefits brought to plants by injection of CO2 in l' aquarium are more to prove (In this regard I invite you to visit the website of the company Producer TROPICA of aquatic plants ) However its use in a tray to discus should not be lightly.
A too strong "dosage" can disturb the discus even cause their death. To avoid this it is imperative to have a table of relationship PH-CO2-KH taking a safety margin. By experience, in many cases of figure, I have observed that the discus do not tolerate the same levels in CO2 that other small fishes.
The presence of a 'permanent test' of CO2 is a minimum, (inexpensive) the best remaining setting by one pH meter control with solenoid valve night break.
The use of CO2 does should in my view take place if it is sought to obtain a beautiful planted tank. If the goal is to lower the pH of an aquarium at discus, lower first the KH your water (Thanks to l’water for example) and you will see your pH lower naturally.
The choice of the aquarium and its equipment
Do not hesitate equip you a aquarium of at least 350 litres. Young discus may use a aquarium smaller (At about 250 litres) but growing your protected will require more space.
Adult once, your discus will require approximately 50 litres of water per person. (Maintenance of type 'set tray.)
Breeders fish are placed in larger numbers but it is farmed and no maintenance "classic.". Used aquariums do not have sand or plants because it emphasizes the practical side. Similarly the rate of change of water is higher.
Side filtration, Choose the security by choosing a good filter. I recommend the brand EHEIM external filters. They have been proven and powerful. Their maintenance is very easy which spoil nothing…a flow of 3 times the hourly volume should be with a volume of filtration in adequacy with the size of the aquarium.
Side heating, There are many brands, but many fans of discus advise you the Jäger brand distributed by Eheim.
Vary the pleasures; specific granules, (Such as Pellets shaped bloodworms "Discus formula shaped bloodworm pellets" Ocean nutrition) mash House for discus, frozen brine (or better freeze-dried), freeze-dried Tubifex…
Distribute in small quantities by adapting the number of meals at the age of fishes.
So, the main lines are drawn, ready to start?
