Further, sandstone or limestone has great popularity with fish breeders. The sandstone can be used in the aquarium to provide a steady and strong foundation. This can be achieved by simply adding sand to the bottom of the aquarium. It is not only a good rock, but it also gives a nice pattern to the aquarium.

While using sandstone in an aquarium, it is necessary to choose the appropriate rock type. For example, if you want to raise your fish from eggs, then there are a few rock types that are suitable for this purpose.

Another rock type is hard, white or yellowish-white or even gray, slate, marble, travertine, and Jasper. They can be porous, giving them the flexibility to soak up water.

Ensure the stones are free from defects

Make sure the stones are free from any defects or chips. Some cracks are unsightly and can cause water to flow off. Too much heat and stress can cause the stone to crack. If you plan to use a marine aquarium for breeding a variety of species, then you can look for stones with a darker color. For general use, a stone with a lighter shade is a good choice.

Deciding on the rock type depends on your goal. There are various types of rocks for aquariums, and each has advantages and disadvantages. The sandstone and calcium carbonate rocks are suitable for most aquariums. However, they have certain limitations and other types of rocks can be used in aquariums.

Choose a fine aqua blue stone with a pattern or patterned edge, and a darker one to avoid cracking. Buy the rock in the correct size and shape.
