fraggin a Xenia
I have way too many in my tank. Any way works fine, I let mine climb the glass, so they frag by them selves. Or you can simply put another rock next to them and they will migrate. Or a new rasor blade works fine, cut and place them on new rocks. I have found elastics to be tricky and cuts them up. Some have told me to stick a toothpick through and then elastic the tooth pick. All I do is prop a rock on top to hold it down, the next day or 2 they are attached.
Hope this helps.
