1. The pH value of the water in which the colorful angelfish is raised should be between 6.2-6.8. If the acidity of the water is too high or too low, it must be adjusted in time. If the water quality of the colorful angelfish is adjusted If the food is not good enough, the colorful angelfish will easily get sick.

So, when raising discus angelfish, you must pay attention to the stability of the water quality. If you raise discus angelfish in a naked tank, the water quality of the discus angelfish is not easy to maintain, so We need to spread sand on the bottom of the tank or raise Discus in a grass tank.

2. When raising colorful angelfish, we must pay attention not to change the water too frequently. If we do not control the water change properly, it will be counterproductive. If the water quality is better maintained when we raise discis in a naked tank, then there is no need to change the water frequently.

Notes on raising colorful angels:

1. The fish tank should be quiet: Angelfish need a large water body, a quiet environment, and a large tank The more water, the better the water quality will be maintained. There should be more fish, otherwise fish will become lonely and fight, while fish in groups are less likely to get sick. Fish competing for food is a sign of health. If there are fewer fish, there will be no competition. If the fish is not active in eating for a long time, it is easy to get sick.

2. Naked or semi-naked tank: You can put some high-end fake grass in the naked tank. It costs about 30 yuan per plant in an aquarium store. Putting sand in it will affect the cleaning. If there is more grass, put less fish. The main thing is to enjoy the scenery, and the fish are just a foil. If you mainly focus on fish farming and appreciate the swimming posture of fish in the water, you cannot put too much grass, or even no grass. Putting more fish and putting more grass cannot have both.

3. Overwater: After buying the fish, soak it in the tank together with the bag for 1 hour. During this period, add a little water from the tank into the bag every 10 minutes, draw a little water from the bag and pour it out, until the bag is filled with water. until the water in it is almost replaced by the water in the tank.
