Carolina Custom Cages Natural Habitat Rocks, Deep Maroon These Natural Habitat Rocks we have found to be excellent choices for basking rocks, as well as for building habitat rock formations for various reptiles, amphibians and turtles. Grouped by general size (medium or large) and color (Blue Green, Deep Maroon, Painted Desert, Uluru Red and Watarrka Rose). Hand selected to typically have at least one side basically flat. The medium sizes about 6 x 8 and large sizes about 7-1/4 x 12-5/8. As a basking rock, theres enough natural porosity that although the rock gets warm accumulating heat, it doesnt get too hot; as glazed ceramic tile or slate would. Since these are real rocks (not cast resin or coated Styrofoam) each one is a little different. Carolina Custom Cages is a division of Carolina Designer Dragons, Inc.
