stones in the fish tank? Most of the small colored stones on the market are not natural, or there is no natural colored stone. The red, green and green colors look good, but in fact they are all dyed, and these dyes will stretch out in the water for a long time, which may be fatal to the fish. So it's better not to put small colored stones in the fish tank. It's better to put some natural stones. You can also consider laying bottom sand.
of putting stones in the fish tank? 1. Increase the ornamental value: Stones in the fish tank are usually used for landscaping, which can increase the ornamental value and make it look more beautiful. The stones of different sizes are placed at the bottom of the jar, and at the same time, they are matched with certain aquatic plants to make it look more like a natural landscape.
