[Elegance Coral]

No no no no no. These animals should out live us. The white ones have a poor track record because they are bleached. When healthy, these anemones are a tan color. Being bleached is not a death sentence though. In the right conditions, many of these anemones can recover. I have brought them through this problem multiple times. In fact, I had one for several years that is now in a friends tank, and still doing fine.

The bright yellow ones are dyed. This is a disgusting practice used to sell more anemones. I've never tried to rehabilitate one of these anemones, and don't know of anyone that has been successful. I wouldn't say it's impossible. Highly unlikely though.
