Hey guys, I picked up a t. maxima clam the other day and put it on the higher 1/3rd of the tank. When I placed it on the rock, it kept on falling off. I got worried and just placed it on the sand. I have had a clam before. it was another t. maxima and did perfectly fine on the sand under t5's. BUT I had a small flat piece of rock underneath it onto which it could take hold onto. I dont have anymore pieces like that and can't find any at the LFS. I do have some "aquascape epoxy" though (the stuff that cures underwater and is colored purple). I've read somewhere that you can take a small bit of that and mold it into a disc and place it underneath the sand and it would attach itself onto the disc. I dont know if i should try this? or try placing it on the rocks again? Any ideas?
