Ceramic Nature Slate Streets have been designed to create caves and breeding areas for some species of Pleco's, Loaches, Shrimps, Cichlids, and other tropical fish. Natural looking, these are made from Spanish slate, containing lots of compartments, (which are closed at the back), making them perfect for fish to explore and live in. To decorate, some species of plants that would usually grow on stone or wood (such as Anubias or Java Fern), can easily be attached to the top or sides to make the hotel look even more attractive. These are very popular with Pleco breeders.
