How to successfully breed Discus Fish?



(10 Steps in Setting up a Discus Fish Breeding Tank)

In Discus Fish breeding, setting up preparation for a Discus Pair is significant. The truth is, once a Discus pair is proven compatible, it is time to set up a breeding tank. Note that, there are lower chances of success if the Discus Breeding Pair is combined in a community tank. Now, for more Royal Facts about the Preparation Fit for a King, let us together examine the 10 steps of Setting up a Discus Breeding Tank!

HEADS UP!!! The following are the relevant Acronyms used in this article:
pH (potential of hydrogen) – a way of measuring whether aquarium water is acidic or basic (alkaline).
TDS (Total dissolved solids) – is a measure of the combined inorganic and organic substances dissolved in water
RO (Reserve Osmosis) Water System – removes dissolved solids like arsenic and fluoride through the RO membrane.    

1st – Ensure the Tank Capacity.

  • The Breeding tank should be a 20 or 29 gallon tank. The bigger the breeding tank is the better.

2nd– Remove Unnecessary Objects.

  • There should be a sponge filter, a heater, a breeding cone, and possibly a light in the Discus Breeding Tank. No decorations are necessary and the things mentioned above should only be the things present in the breeding tank.

3rd– Too Much of Light is Not Good.

  • Breeding tanks for a Discus Fish do not require a lot of light, and too much will be counter-productive.
  • It is best to put the breeding tank somewhere where light isn’t abundant because chances are it won’t be needed.
  • If there is a presence of light, make sure to dim it down. It also a good idea to block a good portion of light with a cardboard. The cardboard should not get hot and it is best to apply a light background of some sort to the bottom and three sides.
  • Avoid mixing your light with dark colors because it will make attachment much harder for the newly born fry.

4th – Water Softness is a Major Concern.

  • The breeding tank of a Discus Fish requires some special conditions and specific water requirements.
  • Water Softness is one of the major concerns of the breeding tank. Note that, Discus Fish can seldom breed successfully in “hard” water.
  • The pH of the breeding tank is not a major concern but should still be initially monitored. As long as the water is soft with low calcium content, the Discus Fish Pair can thrive.

5th – Getting to know the RO system and the TDS meter is a must.

  • Tap water can be naturally soft for the Discus Fish Pair but it is recommended to purchase an RO system and a TDS (total dissolved solids) meter.
  • It is best to test tap water with a TDS meter and  if the TDS is above 100, having RO water is a must.
POINTS TO PONDER !!! WHY IS HARD WATER NOT SUITABLE FOR A DISCUS BREEDING TANK? Hard water tends to interact with the outer surface of the discus egg. This interaction can cause the discus egg to calcify, and then the embryo will suffocate. In extreme cases, it has even been reported that hard water will prevent the eggs from becoming fertilized.  

6th – Knowing what is the best TDS ppm good starting point is very important.

  • After the RO water system is up and functioning, it is necessary to soften the breeding tank water so the Discus Fish Pair can be successful in breeding.
  • It is advisable to have a 80 ppm TDS as a starting point.
  • After preheating the storage container of RO water to 82 degrees, it is a must to measure its TDS.
  • Note that, the TDS at this point should be in the 8-20 ppm range.

7th – It is best to know the two methods in how to buffer the tank water to save resources.

  • After maintaining the TDS, it is a must to buffer the tank water. To buffer the tank water, one can simply add just enough amount of RO waste water back into the RO water to bring our TDS back up to 80 ppm.
  • There is also a commercially available buffering product in the market that can be added in the tank. Note that, these two methods will work and the first method can also save you some money.

8th – Monitor the pH Level to avoid pH crashes.

  • Monitor the pH level of the tank until the water parameters become stable is a must.
  • Keep in mind that the Discus Fish can adjust to quite well to a range of pH’s but they will not tolerate a crash.
  • pH Crash will not happen until the TDS level gets below 30- 40 ppm.
POINTS TO PONDER!!! What is a pH crash? A pH crash occurs when the buffering capability of the water is at its lowest level. This is the result when the minerals that impact pH are depleted and causing the pH levels to crash.    

Note that, every water supply may vary so it is important to monitor the pH level until one is confident that a crash won’t happen.

9th – Monitoring the future outcome of the TDS measurement is a significant way to know the hatch rate of the eggs.

  • If the hatch rate of the Discus is unsatisfactory after having a TDS of 80 ppm, try lowering the TDS to 60, then 40 if necessary.
  • Always remember to monitor the pH each time TDS is drop.
  • If there is no hatch even after lowering the TDS to 35-40, chances are that there is either two females in the breeding tank or the male is infertile and too young to fertilize.

10th – Be Observant, Be Patient, and Be Knowledgeable.

  • In Discus Breeding, water parameters are very important. It is one of the major factors for breeding to be successful.
  • Keep in mind that every water supply varies and do not get too discouraged in hearing others make statements on how they get great hatch rates at a certain TDS that is higher. Truth is, this information is only relevant if both of you have the same water supply.

The preparation fit for the King of Aquariums on breeding is truly specific. Preparing a good breeding environment is not an option, but rather a necessity. One should know how to be observant of each change to ensure success. No matter the circumstances, it is important to be knowledgeable and responsible enough to handle the needs of the Discus Fish Pair on breeding.
