Wow! That is BEAUTIFUL! I have a question. How do you get the cork to stay down? Is it just like other driftwood, where you have to keep it underwater for like a month, or do you have to hook it to something? It is really pretty! When my dad was a kid he said he used cork for fishing bobbers, so I was wondering if it is buoyant enough to do that, how would you get it to sink in your tank? Sorry for so many questions lol I LOVE your tank!
