I picked up a cypt. balansae from my LFS and it same with the stems wrapped in a 2cm-ish wide strip of foam and a metal band around it. I took this off and saw it is 4 separate plant stems wrapped in different layers. Right now I have all 4 planted together without the foam and I wrapped the metal around the bare stems because I couldn't keep them down otherwise. But now I'm wondering if I should keep the foam on too and just plant the whole base? The metal is very pliable and soft (lead?). At the store they were in a tank wrapped in the foam but not planted, just sitting on the gravel.
