i am setting up a new tank and for hiding spots i was thinking of using one of those 3d foam backgrounds and sticking some pvc pipe sections to the back of it and then cutting a hole into it from the front would this work.
thanks i was thinking of just pulling it out to clean it but have now decided not to use this but i do want to know if i can use pavers in there and stack them to make caves and hiding holes, or cobble stone pavers.
