This Clam holder was made to create a safe place for clams and anemones to secure themselves safely out of the sand bed. This holder/cradle can be set anywhere on the sand or rockwork to provide the best light and flow. By giving your clam or anemone a safe and solid mounting space with a depressed groove in the middle, this provides a stable and solid surface for them to attach themselves. These cradles are custom molded to look like natural rock and are made of aragocrete. Color may differ when delivered as it will arrive in a dry state. Color will be more enhanced once it fully absobs water when placed into the fish tank.
