This means if you put the Duncan Coral from very low light to a very high light then it will not open up and show other unhealthy symptoms. That means the sudden change of the light makes the Duncan Coral sensitive.
If you are planning to change the light pattern, then you need to be cautious. The plant needs a slow change of light. This is true for high-to-low and low-to-high.
Solution
If the sudden change of light is the reason behind the closed gesture of Duncan Coral, then the solution is to change the light slowly. For this, you can use natural light. First, place the aquarium in a place with low light and then take it to the moderate and then to a bright place.

2. Water Flow
If you want to decide the flow of water for Duncan Coral then you need to know that it can survive in moderate to high flow. The high flow should also be monitored as the extreme flow of water can cause damage to the tissue.
Special leave in a Duncan Coral is shifted, from a low flow of water to a sudden high flow of water, the damage is more. The Coral fails to adjust to the change and doesn’t behave naturally.
A damaged Duncan coral doesn’t bloom and takes time to heal itself. In this healing period, it will not Bloom and invest its absorbed nutrients in self-care. Also, remember if the Duncan Coral has damaged tissue for a long time it can fail to recover and might end up dying.

3. High Temperature
Duncan Coral is a being of cold water. It doesn’t have a good response in the presence of hot water or even warm water. If the temperature of the water is warm or hot, the polyps and the tentacles get contracted. Therefore it fails to open even if all other factors of the water parameter are in perfect condition.
Solution
The solution to the high temperature that is affecting Duncan Coral to open up is to reduce the temperature. If you have a water heater in the tank then reduce the temperature. Especially if it’s higher than 80 degrees Fahrenheit. The ideal temperature is between 76 to 78 degrees Fahrenheit.
Even when you are reducing the temperature you need to be careful. Do it slowly over a week or two. Otherwise, the sudden temperature change will disturb the other habitats of the aquarium.
If the temperature of the water is due to room temperature, then keep the aquarium away from direct sunlight for a while until the coral opens up.
4. Imbalance of Nitrate
For any kind of coral, the nitrate in the water must be balanced. Low levels of nitrate can cause a nutrient deficiency in the coral. Whenever there is a deficiency of nitrate, Duncan Coral feels distressed. And they don’t respond in a natural way.
As the deficiency of nitrate, excess nitrate is also the reason why the Duncan Coral won’t open up. When there is excess nitrate it can lead to higher levels of ammonia. This high level of ammonia will make the Coral decay.
The Duncan Coral gets busy balancing out the nitrate level and the mending harm that the excess nitrate has caused. Therefore they don’t open up when it’s time and take the time for self-recovery.
Solution
It is optimal to have 30 PPM nitrate in the water of the aquarium tank. It is not too low that there will be a deficiency of nitrate and it is not excess that will create Ammonia in the water.
In case of nitrate deficiency, you can use fertilizers that contain nitrate in moderate amounts. The food that makes sure that the other plants in the tank are tolerable to 30 ppm nitrate. Otherwise, keep the level low or balance it out with other habitats.
If there is excess nitrate, use the filtration method to get rid of the chemical. Also, you can replace the water in the tank. This is a low-cost solution.
5. Feeding Problem
Feeding is an important issue for Duncan Coral. Overfeeding makes the Duncan coral oversensitive. Whenever Duncan Coral over-feeding, the polyp and the tentacles grab more food than they are supposed to. This makes them tired and they refuse to open up.
Moreover, when there is more food in the coral, it attracts other habitats like fish to grab food from the coral. If the aquatic animals of the aquarium are aggressive they can end up causing stress to the coral. Thus the Coral will close up and won’t open up even if all the factors are in moderate amounts.
Solution
If the Duncan Coral is already being fed, then clean the coral. Remove any kind of additional food that is attached to the tentacles and polyps. This way it will not attract the other animals in the aquarium. The Duncan coral will be safe from external harm.
Once the cleaning is done the Duncan Coral is supposed to open up. If that doesn’t happen, change the speed of the tank. You can try introducing full-proof algae wafers as a news feed for the other animals. This way they will not disturb the Duncan coral.
Balancing the feeding is also necessary to remove any excess food from the tank. Especially algae. You can also try and do spot feeding. This means, first identifying how much food Duncan Coral needs and then putting the food exactly above it or on it. Once the food is completely consumed, then go for the second batch.
