Discus Shimmy Details And Causes
Discus shivering from time to time is known as shimmying. Discus Shimmy is a symptom not specifically a disease; Shivering in Discus can be a result of stress, poisoning, and water chemistry issues.
Coldwater effects can also cause your Discus to shiver; poor water quality can cause the Discus to shimmer because it gives rise to bacterial and protozoan diseases such as fin rot, slime disease, and mouth fungus. Poor water quality can also cause poisoning in your tank, such as copper.
Shivering Discus can also be a result of spawning behavior, but a twitching Discus is an indication that other issues are going on. You have to check your water parameters because your Discus might be stressed and observe the pH of your tank with your testing tools. If the Discus fish shiver before a spawn while they look at the exact spot where they intend to lay eggs, they ripple their bodies entirely.
Discus Shimmy Causes
There are Four causes of Discus shimmy:
- Discus Shimmy – Breeding Time.
- Discus Shimmy – Tank Domination Indication.
- Discus Shimmy – Stress Symptoms.
- Discus Shimmy – Disease Infection.
Discus Shimmy – Breeding Time
Before the spawn time watching your male and female Discus really looks nice, They may spawn for a few days or less. Every pair of Discus is different from the other. The dances are more exciting to watch. You may witness bow.
Also, This is when the Male and female face each other some distance apart near the bottom of the tank, and they both swim upwards at a 45-degree angle towards each other. When they have met, they will then proceed downward, again at a 45-degree angle, until they each occupy the others beginning position.
They will start looking for a comfortable breeding surface and begin to clean the area, both taking turns to peck at the surface. As the spawn becomes closer, they will shake as if they were shivering. When they start shaking or shivering, a spawn is drawing nearer.
Discus Shimmy – Tank Domination Indication
Discus are cichlids, and like all Cichlids are territorial and can be aggressive, especially the male Discus, the male Discus can shimmer when they are aggressive towards another Discus.
And the case is not just about removing the aggressive Discus, if the aggressive one is removed the next male Discus in the tank will take up from and become aggressive, it can go like that till you have removed all the male Discus in the tank when it’s remaining two Discus in the tank the more aggressive one can pick the other to show it’s more powerful and during this time you can observe shimmer from this Discus.
Discus Shimmy – Stress Symptoms
Discus Fish can shimmer as a result of stress, severe stress from poor water conditions, improper feeding, unstable pH, harassment from other fishes, etc. When you find your fish shaking or shimmering, then have to make sure that all these stress problems are taken care of before you suspect any disease.
Discus Shimmy – Disease Infection
When the water condition in your tank is poor and unhealthy, it can attract parasites, bacteria, and fungi into your tank, and when any of this affects your fish, it can cause a disease that might make them shimmer. An infection like swim bladder disorder can cause your fish to shimmer when your fish shimmers along with side symptoms like loss of appetite, imbalance in water, clamped fins, bloat she may be suffering from swim bladder disorder.
How To Differentiate Between Discus Pairing, Aggression, or Disease Shimmy?
 Discus Is Infected With An External Parasite
Your Discus fish might lose control over the action of its muscles and nerves and it can be a symptom of a disease or parasite, in this case, you might notice this shivering most of the time through many days or even weeks as long as the Discus is infected, you should also observe the Discus with other symptoms to identify the disease.
 Discus Pairing Behavior (How do you know if Discus is pairing?)
During the pairing and breeding process, Discus fish will always shake in pairs during reproduction.
Your Job to do as an aquarist is to separate them from a spawning tank so that the eggs and sperms will not die unnecessarily, and new fishes can be left to form in the main tank.
When your Discus fish is shimmying or shaking alone, it is most likely she wants to attract a mate, but if they are shivering and shaking as a pair, then they are ready for spawning.
 Discus Is Aggressive
When Discus is aggressive, you will notice that she is shivering while she challenges one or more other Discus to dominate the tank.
That is how you will be able to differentiate between Discus pairing behaviors/when it is aggressive and a disorder.
 Discus Is Stressed
Your Discus fish could shake or shiver as a result of severe stress, poisoning, for example, acidic poisoning, nitrite poisoning- poor water chemistry.
