1. How many traffic lights can a 40 cm fish tank raise A 40 cm fish tank can generally raise 15-30 traffic light fish, but the specific number can be raised depends on the actual situation of the fish tank. If the oxygen and filtration system in the fish tank are complete, 20-30 fish can be raised. Because traffic light fish are animals that like group swimming, the more they are raised, the stronger their ornamental value is.
If the filtration and oxygenation in the fish tank are not perfect, it is recommended to raise about 15-20 fish. If aquatic plants or other aquatic plants are planted, it is recommended to reduce the number of raised plants.
2. How to raise traffic light fish1. Water temperature: Traffic light fish is tropical fish and likes a higher water temperature. It is best to keep the water temperature at about 22-26 ℃ when raising artificially. After entering winter, the water temperature should not be lower than 20 ℃, otherwise it will have a certain impact on their health.
2. Water quality: Traffic light fish like weak acidic water quality, and the PH value can be kept between 5.8 and 6.8 when being reared artificially. They prefer soft water, and breeders should choose tap water or distilled water after drying.
3. Feeding: Traffic light fish are omnivorous fish, and breeders can choose a variety of feeds to feed. They prefer to eat live bait such as red worms, water fleas and silk earthworms. Breeders can choose these as their staple foods, and then match them with some tender leaves or fruits of vegetables to ensure balanced nutrition.
