- Try to keep the water between 22 – 26 degrees Celsius with a pH of 6.8 – 7.8.
- Change the water at least 20% each week. By installing a filter in the aquarium.
- Aquarium design with slightly dense plants. This serves to hide female swordfish when they are annoyed by males. In addition, this is also good for the spawning process and juvenile fish can immediately take refuge in it.
- Provide them with a varied diet with regard to intake, nutritional content, other consumer reviews, and the impact of these foods on aquarium cleanliness.
- Close your aquarium. Because these fish include fish that are active and reliable jumpers.
- Take care of these fish more females than males. Because if there are fewer females, then the male will disturb the female until finally the female is stressed and dies.
