Your two new ricordeas are just beautiful! Here in Northern Caifornia they sell for about $25 - $35 per polyp (pricey) and one litttle polyp floats away so easily. I was given an orange ricordea polyp that wasn't secured to anything and I had a dickens of a time finding a place for it where it didn't float away and still got the right light. I finally found it aplace and now it seems to have attached itself and is finally growing.
Good luck with these beauties!
