Thanks, my rics just multiply on there own. I have also experimented a bit and propogated my pinks. Propogation is very easy. I find one that is on a nice flat piece of rock and take a scalpal and cut it into 4 pieces, trying to get a piece of mouth(not necessary). Then i take a pair sharp plyers and cut the rock along the cuts in the ric. I like this method because it is a pain to try and attach a loose ric to a rock. If you can't do this, just place the pieces in a box with some small pieces of rock rubble in a very low flow area. It could take weeks for them to attach. If you are planning on fragging an expensive pink ric, please make sure it has been in your tank a long time. All the rics you see in my tank, i have had for at least a year and in some cases over 2 years. Hope this helps
