Aquarium rocks can help and beautify your tank. Apart from beautifying or adding a view to your tank, rocks also provide hideout and breeding places for your fishes. Aquarium rocks can also be used to be ornaments and anchor plants in your tank. The surface of the rocks helps aquarium plants to attach themselves to them. To choose the right aquarium rocks which are popular, you have to consider some factors. For example, factors that should be considered include how solid the rock is, does it dissolve in water and does it crumble.  Make sure that aquarium rocks are well anchored or are neatly tucked on your tank to be sure that the rocks would not endanger your fish lives.

You should also not chose a rock composed of calcium. Rocks that contain calcium are called calcareous rocks. To test a rock for this, put drops of ordinary white vinegar on top of the rock. If the drops bring out bubble or foam then that means the rock is calcareous. Aquarium rocks with high calcium deposits are very harmful to your water and your fish. The presence of calcium in water greatly affects the chemistry of water in your tank. The pH and hardness of the water will be changed.
