Zebrafish will starve to death if they don't feed for a few days. If they are young zebrafish, they can persist for a short time. Because they are small in size and have weak predation ability. If the breeder does not feed them for more than 4 days, they will die.

As they reach adulthood, their need for food and nutrients will decrease. If the water in which they are raised can be kept clean and fresh, they can last for one month. There are also some zebrafish with strong physique, which can last for about 2 months.

Although zebrafish can persist in not feeding for a long time, it is not recommended that breeders feed at too long intervals. Especially in juvenile zebrafish, if they are not fed regularly and quantitatively, it is likely to affect their growth and development.

1. Feeding amount: Zebrafish are small fish, and their appetite is not large. The breeder should not feed them too much at a time, and the amount of each feed can be eaten within 3-5 minutes.

2. Feeding frequency: Zebrafish feed at different growth stages, and it is best for juvenile zebrafish to feed 2-3 times a day. Because they eat a small amount of food, but the demand for food is relatively high, the breeder needs to feed them a small amount of food many times. When they are adults, they can be fed 1-2 times a day. Because they will eat more as adults, their demand for food will also decrease.
