when they are hungry? It is possible for goldfish to bite other fish when they are hungry, especially those smaller than themselves. Biting fish is just an instinctive reaction to hunger, and they will not eat the fish after biting it. Breeders should ensure adequate food at ordinary times, preferably twice a day, preferably at 8 A. M. and 3 P. m., and the amount of each feeding can be eaten within 5-10 minutes. This can reduce the occurrence of such situations.
1, space is insufficient: Although goldfish disposition is gentle, but also can appear unavoidably the circumstance that grabs domain. If the goldfish tank is too small or too dense, they will often fight. The way goldfish fight is to bite each other. If you find that goldfish are biting each other because of territorial disputes, you can try to replace a larger fish tank or reduce the feeding density.
2. Estrus: When the goldfish is in heat, the male will chase the female and bite the female. The breeder can observe whether the fin of the male fish has a row of small white spots, if so, it indicates that it is in estrus. This kind of mutual chasing and biting belongs to the normal estrus reaction of goldfish, as long as the bite is not particularly serious, there is no need for intervention.
