What should be laid at the bottom of the fish tank? Can we not lay anything?

There are generally three options for the bottom of the fish tank. The first is the bottom sand, including ceramsite, rain forest sand and cosmetic sand. Different bottom sands are suitable for different fish. The second is water grass mud, which is generally needed for grass tanks. Compared with the general bottom sand, water grass mud has certain nutrition, which is very helpful for the growth of water grass. There are also pebbles, but be sure to use smaller ones, but they are still not easy to clean.

1. What should be

laid at the bottom of the fish tank? 1. Bottom sand: Bottom sand at the bottom of the fish tank is the most common choice. There are many kinds of bottom sand, such as ceramsite, tropical rain forest sand and cosmetic sand, etc. According to different needs, different bottom sand should be chosen. Ceramsite is suitable for many common fish. Tropical rainforest sand is generally used to raise South American fish, while cosmetic sand is more suitable for Sanhu cichlid, special-shaped fish and so on.

2. Aquatic grass mud: Aquatic grass mud is generally used for planting aquatic plants. Compared with conventional bottom sand, it can provide certain nutrition, so that aquatic plants can grow better. It should be noted that this kind of thing will be powdered after a long time, so it should be replaced regularly.

3. Pebbles: Smaller pebbles can also be laid at the bottom of the fish tank, similar to the bottom sand. However, its gap is much larger than the bottom sand, so the excrement of fish is easy to fall below, if the filtration in the tank is good, if the filtration is not good, it is easy to cause water pollution. It is also possible not to lay things at the bottom of the

fish tank, which is equivalent to raising fish in a naked tank. Although there are no decorations, the dirty things are easier to clean up, which is more convenient for raising fish. Usually at the beginning of fish farming, people like to lay things to make the fish tank look more like a natural landscape, but after a long time, it will be removed, and bare tank fish farming is more about the situation of fish.
