I've found that PetSmart has some highly realistic individual small plants. Especially if you trim off any fake "root" looking stuff. If you want to see what I mean, check out my most recent photo of my tank in my thread, Final Tank Setup. All the small sized plants are from PetSmart, and they look great.Never been a huge fan of fake plants but I'll definitely look for some good quality ones. They would like nice in between the stones!
