I know It's been an extraordinarily long time since I posted this, but I did finish it! Here are some pictures of the finished project!
I ended up going with the GBB. It's still in a smaller container and secluded in the top portion of the tank until it molts a few more times. I used tile grout (bone color) to make the inside of the cave and then used a polyurethane wood finish to seal it not only for moisture reasons but also to give it a cool slimy look to make it look more limestone-esque. I hope you like it!
