Wow! I like the river rock ones! I may have to try that! Be aware though that the silicone that shows will become more visible underwater (I have no idea why, but it is very annoying). Also, depending on your water, it may turn white after a while. This happened to me when I glued a bunch of lava rock together for retaining walls. Eventually, the white was covered in algea and it is now not really visible at all. The one way that I found to prevent silicone from showing up was to sprinkle sand on the wet silicone and really pack it on.

Another thought...for the slate trapezoid in your pictures...make sure that one is far enough away from your glass that if it collapses it wont hit the glass on it's way down! I had a slate "table" sort of arrangement in my tank once, and the silicone gave out...it just collapased downwards, so no harm done. But if it had hit the glass...

Try a terra cotta (clay) pot. Purchase the size you want, turn it upside down, use a masonary bit of the appropriate size to drill the size of opening you desire (drill a side or enlarge the bottom opening). You can also cut the pot in half using a masonary blade or tile saw (half a pot makes a nice cave). Cover the outside using two part epoxy and sand/gravel. If you want to get really creative, buy some expanding pond foam and use river rock and foam to build structure off of the pot.

Yeah i plan on doing the sand sprinkle as well.. wanted to wait til i was finished, will just add a bit more silicone.. and the slate, has a bottom on it that will sit under the gravel for stability.. I also plan on running anubais nana and baby tears up and around the slate and just some baby tears or java moss on the river rock. Good advice though, thanks.
