Dos and Don'ts of Decorating a Fish Tank ? You need to know exactly how big the bottom of your tank is. You also need to keep in mind anything else you might already have. ? Are you adding plants? How many? The last thing you need to keep in mind is exactly what you want your tank to look like. ? Many people often go overboard when it comes to picking out decorations for their tank. It can be really easy to do, and let's face it, it's really fun to pick things out for your tank. ? Just keep in mind how much space you have to work with. Do you really have room for that sunken ship, fake corals, and the giant treasure chest? ? Sometimes simpler is better. One large piece and a couple of smaller pieces are all you need, especially if you are adding plants. Things That Don't Belong in Fish Tanks ? Ceramics (if you cannot eat off it, don't put it into your tank; they can leach chemicals and heavy metals) ? Wood (unless it was purchased at a pet store and has been pretreated) ? Rocks (some rocks have minerals that you do not want in your tank) ? Shells and corals (in freshwater systems, they will add calcium that the system does not need) ? Some glass (glass is safe unless it has sharp edges or has been painted) ? No matter what you use for decorations, except for live plants, you are going to need to clean it at some point.
