My tank is cycled and I am waiting six more weeks to add fish. I am now trying to aquascape. Any thoughts on using epoxy? I have an acrylic tank, so it would have to fit through my cut outs. Also I read an idea to prop up all of your rocks with short pieces of PVC. (the height of my sand bed only) so that cleaning creatures can get underneath to get out the detrius. Any ideas about this? I want to get a bicolor blennie and I dont want him to get smooshed.
