Breeding Discus Fish
Discus Fish Water Quality
For best Discus egg hatches the water should be between 6.2 and 6.9 Ph, with a temp of 28 to 30 deg Celcius and a Gh of less than 1 Deg Gh.
Without a doubt the best water for breeding Discus fish is that produced by a reverse osmosis unit. No serious Discus fish breeder should be without one.
Make sure that the filter canisters and membrane are not past their best. The best ro units are classed as at least a five stage unit. They have three pods; containing a pre filter, a carbon block cartridge and a CBR2 metalex cartridge. Above those you will find the ro membrane and a post deioniser, ensuring a TDS (total dissolved solids) of zero.
At Midlands Discus we use 100% reverse osmosis water re mineralized to a level of between 1 and 0 Gh with HMA (heavy metal filtered) water for breeding Discus fish. Obviously ammonia, nitrite and nitrate should be nil if the reverse osmosis unit is functioning properly.
As the reverse osmosis water / HMA mix is un-stable at such a low general hardness, a twenty percent water change in the Discus breeding tank is carried out on a daily basis, one hour after the last feed.
All reverse osmosis water should be aerated and heated to the same temperature as the Discus fish breeding tank before use. The Discus Fish Breeding Tank
A Discus Fish breeding tank is really pretty basic. The bare essentials are a dim light, spawning cone, sponge filter, a heater thermostat and a tank of capacity say 90 liters i.e. 18"x 18"x 18," for a medium sized breeding pair of Discus fish.
