1. What is good to lay at the bottom of fish tank 1. Bottom sand: Some bottom sand can be laid at the bottom of fish tank, and different fish can choose different bottom sand. Like common ceramsite sand, it is more suitable for most ornamental fish. Tropical rain forest sand is more suitable for South American fish. Cosmetic sand is more suitable for Sanhu cichlid, heterosexual fish, etc.
2, aquatic plant mud: Breeders can also spread some aquatic plant mud on the bottom, which is more nutritious than ordinary bottom sand and can make aquatic plants grow better. Some fish that like to grow in aquatic plants are more suitable for spreading aquatic plant mud at the bottom. However, the water grass mud will be pulverized after being used for a long time, so breeders should pay attention to regular replacement.
3. Pebbles: If breeders want to enhance the ornamental value of fish tanks, they can also lay some pebbles. However, large pebbles cannot be selected, and the void of pebbles is large. If the filter is not strong enough, it is recommended not to place it.
2. It is better to spread things or not in the fish tank for fish farming. It depends on the habits of fish. Some fish prefer bottom sand or aquatic plants, so breeders need to spread things in the fish tank, which can better simulate the wild environment. There are also some fish that prefer clean and refreshing water quality, so it is more suitable for them to grow if the breeder does not spread things in the fish tank.
