I'm setting up a new tank for a 28" lung fish and i would like to have some rocks in the landscape. I know these guys are known to toss some around and i was wondering if I could attach them to the bottom w/silicone and be ok. They have been in a tank previously and are very smooth witch would be good for adhesion. Anyone given this a try, may not be worth the effort but I don't like it looking so barren.
