This was my first bubble tip anemone (Entacmaea quadricolor). It had the most beautiful colors, a kind of metallic green with nice pink tips that really bubbled.
This is the same specimen as the one seen with a porcelain crab in another post.
This bubble tip anemone has lived in my display tank for about 8 years when they eventually died when the tank has experienced some major problems.
Fortunately it has split several times, and I have both sold pieces of it and even gave away some.
I was told at least on one occasion that a bubble tip anemone being sold in a Marine Aquarium Society of Toronto auction was a piece of this guy. So it has apparently continued to split in other people’s tanks.
So even if the “original” has died there are probably many copies of this bubble-tip anemone still living in various reef aquariums.
Sea anemones don’t really age, they just get bigger and then split into two. They appear to be immortal.
