AAHA! Shalu, I was wondering about that, LOL!
Tying up the sockets? Hmmmm.... where there's a will, there's a way, huh?
My solution was to use an index card as a template of how much headroom a bulb would have, centered around the socket. Of course, I looked like a doofus in Home Depot holding up my cut-up index card to the bulbs in their plastic packaging, but hey, for the sake of my aquariums, it was worth it.
So oocfish, when it comes to riccia, I've had various amounts in my tanks, but never had the patience to "do" anything with it. Generally, I'll recognize it and toss it back into whichever tank it came from. It just becomes part of the floating rack - baby watersprite, large frogbit, and riccia, floating in a corner. It seems like such a "holy grail" of a plant, I'm reluctant to toss it. But I also work way too many hours to actually sit down and tie dozens of little pieces of riccia to plastic windowscreen, etc to make a carpet or some other decorative form out of it, as many websites advise. Lazy? or Realistic? We all have to find that balance, LOL!
Best of Luck!
