REALISTIC APPEARANCE: This Small Deco-Replicas Stone Aquarium Ornament & Hideaway resembles natural granite. Not only does this piece compliment the interior décor of many modern homes, it also serves as a hideaway and swim-through for your fish. Perfect for cichlid tanks, since they’re territorial fish, and must create their own space. EASILY STACKABLE: Our granite-like ornaments come in different sizes; individual units are offered in Small and Large. Stack or arrange these stones however you’d like within your tank. The possibilities and combinations are endless! SUPER SIMPLE TO CLEAN: Simply wipe down and rinse off ornament with warm water when you are cleaning out your tank. Never use soap, as the residual soap particles can harm your fish. It’s safe for both freshwater and saltwater aquariums.
