So I have this crazy idea. Since I plan on adding a couple Morays to my tank I thought up(Sure it's already been done never seen it myself though) I want to make a Moray hideaway. Is there anyway I can cut a piece of PVC in half then attach it to the side of the aquirium on the bottom so it can be half way dug into the substrate and the remainder covered up with LR. Here's the kicker I would like for it to be able to be removed if it gets old or something.
