I have a Tube Anemone for sale. It is white with a neon green center. The tube is probably about 6" long and the span of the tentacles is about 4-5". This is a pretty cool little critter but I just don't have a spot for him at this time. http://m.liveaquaria.com/product/prod_display.cfm?c=497+499+636&pcatid=636
