my answer is: angelfish is relatively easy to raise, but it also needs some skills and precautions.

First of all, angelfish is a tropical freshwater fish, which is suitable for living in an aquarium with a water temperature of 24-28℃. Water quality is the key to the culture of angelfish. It is necessary to change the water regularly and control the indexes such as PH value, ammonia nitrogen and nitrate to keep the water clean and stable.

Secondly, angelfish are gregarious fish, and they need a certain number of the same kind of fish and suitable decorations to provide them with swimming and hiding space. At the same time, angelfish is peaceful and will not attack other fish, so it is suitable for mixed culture with other peaceful fish.

In terms of feed, angelfish can eat dried fish food, freeze-dried worms, blood worms, plankton, etc., and can also add appropriate vitamins and minerals to supplement nutrition.

Finally, angelfish are relatively tolerant, and do not need a complicated and elaborate feeding environment, but they still need regular observation and maintenance to ensure their health and happiness.
