Rocks For Aquariums – Choosing A Rock Type
No stone is suitable for all fish. Some rocks are not suitable for all kinds of fish. A rock must be chosen according to the species of fish and their requirements. The size of the rock and its level of hardness should also be taken into consideration.
Probably the most common example of a rock used for aquariums is the coral rock. These have many benefits and drawbacks. In aquariums, these rocks act as barriers between the fish and the coral. The coral rocks may include the popular “scoop” type of rock, which acts as an air stone.
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. This is good for growing fish from eggs because the crystal coatings protect the eggs against damage.
Hence, you should be aware that the heat-sensitive species include some types of corals. Hence, these will need a temperature-controlled environment for them to survive. The rocks must be of good quality and at the right level of hardness. The rock surface must be smooth and without any grooves or holes.
This type of rock can be of soft blue color and is available in soft and mild aqua blue stone. This type of stone is light in color and comes in a variety of shades. They are suitable for fish that are water-loving or need to live in shallow water. It is also good for koi, tangs and many others.
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. In fact, the lava rock is more porous than the E.E. crystals. Stones for aquariums should not be too thin or too thick. If the stones are too thin, they may not be able to absorb 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. Your pet store clerk can help you decide.
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.
