Mix color for reselers.

Below 8 cm (3 “), it is quite difficult to differentiate the colors of the discus.
There are groups where Discus are very similar and I do not suggest you mix together.
But you can mix between groups, like browns with oranges.

Brown :
Stendker Téfé
Alenquer
Santarem

Brown with small blue :
Brilliant Turquoise
Red Turquoise
Red Scribbelt
Leopard Snake Skin
Snake Skin Red
Snake Skin Blue
Solid x Snake
With experience, you will make a group of all Snake Skin because they have more stress bar, 14 instead of 9 normally.

Brun with more blue :
Solid Turquoise
Kobalt

Solid blue :
Blue Diamond

Orange :
Pigeon Blood
Pigeon Blood Red
Pigeon Blood Blue
Pigeon blood silver
Pigeon bl. Snake
Checkerbaord (new)
Solid Fire Red
Marlboro Red

Other :
Dark Angel

Water

Our Discus are raised in water with following parameters :
General hardness : 15 GH (dH) – 26 TH(dF) – 270 ppm(mg/l)
Carbonate hardness : 8 KH – 14 TAC – 143 ppm(mg/l)
pH 7
Conductivity : 800 µS
Temperature : 30 °C / 86 °Fahrenheit

If your water is not exactly the same characteristics it does not matter, they acclimate to it.
They accept water with the following parameters:
General hardness :  0-30 GH (dH) /  0-55 TH(dF) / 0 – 535 ppm(mg/l)
Carbonate hardness :  0-25 KH /  0-45 TAC / 0-445 ppm(mg/l)
pH 4.0-8.3
Conductivity : 150-1200 µs
Temperature : 28-30°C / 83-86 °Fahrenheit

I advise you for your water changes to keep your new water in a bucket, tray or other and put a water or air pump to circulate water for 24 hours with a water heater.

The best is to filter the water with UV sterilizer during the 24-48 hours.

There are also different types of water purifiers cartridges, which are very good to get rid of some heavy metals and chemicals. With this type of system, you do not have to keep your water 24 hours.

Always wash your hands with rubbing alcohol 70% and rinse with water before touching water fish.
