1. Generally, it is best to raise several rodents and fish The number of rodents and fish culture has a great relationship with the size of the fish tank. It depends on the way of feeding. Normally, a 30 cm long fish tank can raise 10-15 rats and fish, and a 40 cm fish tank can raise 15-20 rats and fish. If there are filters and oxygen pumps, the number of rearing can be increased. Because rat fish have strong cleaning ability, many fish farmers will raise several to clean the moss and food residue in the fish tank. If rat fish are raised together with other ornamental fish, it is best not to raise more than 10 fish.
2. How to raise rats and fish1. Equipment: When raising rats and fish, it is best to install filters and oxygen pumps, so that they can live better. If conditions permit, you can spread sand and plant aquatic plants in the fish tank. Because rats and fish like to live in a hidden environment, they can live more comfortably with aquatic plants.
2. Water temperature: Rats and fish are tropical fish, and their favorite water temperature is 22-26 ℃. If the breeder has the conditions, he can install heating rods to keep the water temperature in this range.
3. Water quality: Rats and fish like neutral old water, and the frequency of water change by breeders should not be too high. Usually, water can be changed once a week. If there is garbage and food residue in the fish tank, the breeder can fish it out with a net.
4. Feeding: Rats and fish will eat a lot of moss and algae in their infancy. Breeders do not need to feed too much food, but only need to supplement them with some animal feed regularly. As adults, rats and fish are less interested in moss and algae, and their appetite will become larger. Breeders need to feed them in small quantities and many times to ensure their adequate nutrition.
