Silicone can be found in almost any fish store and is usually available in clear or black. Sealants designed for aquariums are safe for fish and aquarium tankmates when fully cured, but stay away from other sealants like those used for bathroom or hardware applications. You can use sealants to make caves from pieces of rock or rubble, glue shells, stones or other decorations together, or even to cover things like PVC or plastic “caves” with substrate or rocks to form a more natural-looking hideaway. Note: The tank in these photos has a custom background created by arranging and attaching layered slate with black silicone. The effect of the rock wall is rather permanent, but impressive as it adds dimension. This background was applied before the tank was set-up.

Of course, there are always disclaimers. These tips are just to give you an idea and starting point for your own creativity. Always make sure any non-aquarium ornaments you re-purpose for your aquarium are very clean and are safe for your fish, inverts and water chemistry before adding them to your aquarium, especially in extreme aquarium conditions like saltwater aquarium, low pH/acidic aquariums, high temperatures and sensitive or very aggressive animals. Make sure all objects are free from chemicals and sharp edges are sanded down or covered with silicone to avoid injuries to yourself or your aquarium residents. When in doubt, feel free to ask and we’ll be happy to help you figure out if your new decorating idea is a safe one!
