I have a lot of experience keeping fish, but am new with reefs. I am having problems affixing my corals. At first I found some holes in the rocks to put them in. Now I have used most of the smaller holes. I have a tubinara that I had used an entire tube of epoxy to affix. It stayed for about a month but tumbled over recently. I also have a toadstool leather that I am not sure how to attach. I have even tried using superglue gel, but I think the surface area is too incongruent for it to work. My poor corals!
Any ideas? Should I try more epoxy?
