I have had this anemone for about 2 years and it keeps splitting, it was literally taking over my tank. I have been able to remove 3 which are 4-6" in diameter when fully open. They are a very hardy species and have done really well in my tank over the years. Not sure of the exact species but they have a pink mouth/foot, white tentacles, and purple tips. Price $20 each, I have them in a large tupperware in the tank until I find buyers, so the earlier the better. I can be available during the evening on Monday or Tursday for pickup.
