Goldfish will generally not starve to death if they are not fed for ten days. Goldfish have relatively strong tolerance. However, because young fish have less energy reserves, if they are not fed for 10 days, they may become sick or become very thin. You still need to feed your goldfish regularly, usually once a day. If you are away from home for a period of time and cannot feed your goldfish, you can also use an automatic feeder to feed your goldfish regularly, which will help maintain the health of your goldfish.
Precautions for raising goldfish:
1. Goldfish must not be fed too much. It does not know whether it is hungry or not. Eating too much may cause enteritis. You might even be strangled to death. Moreover, eating too much also produces more excrement, which will cause the water quality to deteriorate quickly.
2. If you use tap water to raise it, you need to dry it for 2 days before pouring it into the fish tank. Or you can raise them directly with milder water such as spring water, well water, lake water, river water, etc., which is very suitable for goldfish to survive.
3. The density of raising goldfish should not be too high, which may cause hypoxia in the goldfish. If you find that a goldfish has its tail falling off or feeling listless, you can put some special salt for goldfish to sterilize and adjust the water quality.
