Attaching Ricordea

[walloutlet]

I know this probably has been asked a million times, but how in God's green Earth do you go about making a Ricordea stay put. I have one at the bottom of my tank in a spot I would consider low flow. I can not make it stay, using a rubber band is not an option as the rock can't come out.

I have it trapped in a net against the rock because I am tired of tearing my rock apart looking for it and having to spend half my time battling with my Perc's (they are very defensive of their cave, VERY DEFENSIVE!)

Any suggestions on keeping this Ricordea in one spot. Do they have a base that encrusts to things or is it more like an anenome where it will roam until it finds the right spot? You know burried way under a rock so no light can reach it.

Any help would be great. Thanks!
