? The colorful angelfish can change the water every 3-4 days. Because they like old water, the frequency of water change does not need to be too high. But they are more sensitive to water quality, if the water quality becomes worse, it is easy to cause disease, so breeders need to clean up the garbage in the fish tank every day. The amount of water changed by the colorful angelfish does not need to be too much, and the amount of water changed each time can be controlled at one third of the total amount of water. It is better to form a rule for the time and amount of
water change, so as to ensure the water quality and temperature, and not to stimulate the fish. When you change the water for the colorful angelfish, you need to inject it slowly. Remember not to pour it directly, because the current will impact the fish body and make the fish have a stress reaction.
colorful angelfish? The best way to raise colorful angelfish is to use weak alkaline water, because their origin is the Amazon River Basin, because there are many rotten leaves in the water, forming a weak acid water quality, so when raising colorful angelfish at ordinary times, we should also ensure that the water quality is weak acid. But tap water is generally weakly alkaline, breeders had better use PH paper to test before use, if the difference is too large, you can use oxalic acid to adjust it. It should also be noted that tap water contains a lot of chlorine, which has an impact on the health of colorful angelfish, and breeders need to be exposed to the sun for 1-2 days before using it.
