fish tank to put the stone, must first look at the contour, had better choose some surface smooth, if too sharp, possibly will injure the fish. At the same time, pay attention to the size, too big stones will occupy space, which may affect the activities of fish. Before putting the stone in, it must be cleaned. It is better to soak it in potassium permanganate solution, which can kill the bacteria on the surface and avoid harmful bacteria entering the fish tank.
else can be put besides stones? 1. Bottom sand: Bottom sand is the best choice besides paving stones. The common ones are ceramsite, rainforest sand and cosmetic sand. The particles of ceramsite are relatively large. It is suitable for raising small fish such as guppies and mini parrots. It is not easy to damage the water, and it can also adjust the hardness. Rainforest sand is suitable for raising some South American fish, such as lantern fish, brontosaurus, etc. Cosmetic sand is mainly matched with Sanhu cichlid.
2. Sunken wood: Sunken wood is more suitable for some fish that like acidic environment. It can change the pH of the water body so as to make it acidic. Compared with other ways of change, the advantage of sunken wood is that it will not cause fluctuations in water quality. Slow change can be better accepted by fish. But putting this kind of thing can easily cause the water to turn yellow.
3. Aquatic grass mud: If you want to plant aquatic plants in the fish tank, you'd better lay aquatic grass mud at the bottom of the tank, which can not only fix the aquatic plants, but also provide certain nutrients, but it will pulverize after a long time, so you need to turn over the tank regularly.
