I'll show you how to frag those
. It's REALLY easy. You take a razor blade and cut it off of the rock. Whatever is left on the rock will grow back and the part you cut off will heal. Then you can take scissors or a razor and just cut the loose one in half.
Thats it, pretty simple.
If your interested I'd also be interesting in trading you for one of those rics. How about a couple of those big green rics you saw in my tank for 1 of those??
