1. It is generally recommended to use natural gravel for the aquarium. Colored gravel can be used, as long as it is professionally made, certain cheaply made color gravels can be toxic to fish in your aquarium.
2. It is a good idea to keep carbon on hand in case of emergencies. Carbon can be used to soak up anything harmful that may be introduced into your aquarium. So keeping an emergency stock can be a life saver.
3. Make sure to keep a log on hand to update any changes in the aquarium. This will help you keep track of changes in your aquarium much more easily. Keep your aquarium log in a place where you wonít forget it.
