hello all! I am in the process of building a frog rack, and have been looking into cork panels as a viable background/visual barrier for the tanks.I have searched online and the forum, I am just trying to find the right safe panels to use. For some reason older posts on here are not showing images for me. The best source and product I have seem to found is http://www.corkstore.com/Products/I...-Tile-Dark-305mmx305mmx9-5mm-Nopsa?quantity=1 has any one else used these or have an alternative idea of where i could get something similar? My rack is going to start with 4 20 gal talls so id like something that's not going to take up a ton of room.Any advice would be greatly appreciated.
