Below are photos and pricing for my available Rock Walls that I have ready to ship. Please contact me at StickyGeckos@gmail.com with your tank dimensions and any suggestions if you would like to have me make a custom order for you. All my rock walls are sturdy and come fully airated so they are ready to put into your pets tank. I've used all none caustic and aquarium safe material but would prefer if they are not used under water. Thank you!
