If the shit pulled by goldfish is black, brown or green, it means that their body is relatively healthy and their digestive system is relatively normal. Their poop has a great relationship with the food they feed. If the breeder feeds them with more fish and insects, the color of their poop is brown or brown. If the breeder feeds them more synthetic feed, the poop they pull out is black. If they eat too much moss and algae, the feces they pull out are green.
But if the feces they pull out are white or gray, and there will be long stools, then there is something wrong with their digestive system, and the breeder needs immediate treatment to avoid affecting their health and life.
2. How to deal with goldfish excrement1. Add clean fish: Breeders can add some clean fish in the fish tank, such as common scavengers and rat fish. These clean fish will clean up the feces of goldfish, and regularly clean the moss and algae in the fish tank to avoid the deterioration of water quality.
2, Filter: Breeders can also install a filter to slow down the deterioration of water quality. Moreover, the filter can also extract the feces of goldfish from the bottom of the fish tank without affecting the normal growth of goldfish. This can not only reduce the frequency of cleaning feces, but also reduce the frequency of changing water.
