Fish tank rocks are great decorations to give depth and a natural look to your aquarium.
All you have to do is keep a few important things in mind while selecting fish tank rocks. It is important to avoid rocks that are rusty or have pyrite (fool’s gold) in them as these may contaminate the water with harmful metals. Good fish tank rocks should be easy to clean and heavy enough to sink but not so large or heavy that they may break the glass. They are also fairly cheap to buy. Remember to not use just regular outdoor rocks in your fish tank as they may contain germs and other chemicals that could adversely affect your fish.
Rocks that provide good decoration in an aquarium include pumice, slate, sandstone, lava rock, and limestone. Just make sure to thoroughly clean the rock before you use it as decoration. River stones that have been shaped and polished by natural river currents make for beautiful decoration. It is also a good idea to consult with your local pet store for buying and installing any fish tank rocks.
Using fish tank rocks as decoration is easy. You can place a large rock with caves or holes in a corner. These provide your fish a place to play and hide. You may also arrange smaller rocks by piling them onto each other and arranging fish tank plants and driftwood in between the rocks. Larger fish tank rocks can be layered on top of each other to create caves and tunnels for the fish to enjoy. Just ensure that any structure you create is stable and will not fall on your fist. You may use safe silicone adhesives to hold our structure together. Another easy way to add flair to your fish tank would be to coordinate the color of fish tank rocks to the fish you have. For example, if you have a small tank with a few goldfish, you could opt for white rocks and green plants. These would give a cheerful look to your fish tank and brighten any room.
Using fish tank rocks as decoration is easy. Just make sure that the rocks you choose are clean and will not contaminate the water. Make sure to consult with your pet store if you have any doubts at all.
