A giant decorative stone with hollow cave interior. Eco-friendly and unique, Underwater Galleries replicas are molded with care, hand-glazed for eye-catching perfection, heated to more than 2100 degrees, and forged into high-fired ceramic. Each piece is indivudally poured - no two are exactly alike! These ceramic replicas make ideal homes for many varieties of live-bearing tropical fish, most notably African and South American Cichlids. Spacious hollow interiors encourage exploration while providing secure breeding niches and a defensible, stress-reducing refuge.
