my advice is make sure your water quality is perfect and you have enough lighting to support this type of anemone.
IME and research, most host anemones dwindle away in aquariums over the course of 6months or so. very few experts have a surivival history of keeping them over 2years, something like 4%. i can probably find the article, you could too- search the web for anemones.
host anemones have a lifespan in the ocean of over 200 years.
has anyone on this site had a good experience with them? i.e. long tenticles, bubble tips, sabae, carpet....
