What can you say about lava rocks in general for amphibians? I plan on using them for my tree frog tank for RETFs. I want to build a waterfall out of lava rocks but I am afraid that the edges of the rock will be too sharp and may damage the skin of my pets. I figure that it is okay given that lava rocks are extremely popular for fish of all types and sizes. Also Petco reps also using all sorts of lava rocks in their anole enclosures. Anyone with experience on this issue, please help me!

I have had large sculpted lava rocks as fish tank decorations before (african Cichlids). I took the rocks out after losing a couple of fish that chased each other into the rock work. I personally would avoid using it, unless it was completely covered in moss, and even then I wouldn't use it with aggressive feeders like WTF's .

I once siliconed lava rocks to the some acrylic to hide the edges. That was for gray treefrogs and I had no problem. I mostly use them for biomedia now. I would inspect each piece. Any extremely sharp edged can be taken down by grinding on some pavement or a brick.

I take that back, I used rocks that were similar in color, but were much smoother. In which case, make sure you grind down sharp edges and limit how much you use in the tank.
