I was at one of our local nurseries last weekend, and was able to find the following in a 2 for 1 sale (probably 4" pots)
Gold Anemone
Sea Scallop
Hermit Crab
Molton Coral
I was able to get 8 plants for 20.00 I will be sure to take cuttings from these later in the season. I was so excited to find these!
