No it's not, if you have an occ clown it's natural host anemone is the magnificent. However this is an expert nem. You could try a bubble tip or long tentacle but be aware your clowns may never host it (you can't make them) especially if they are tank raised clowns. Mine host a bubble tip but it took them about a year to find it! You should also know that nems require very high lighting and mature, stable tanks. Most people recommend waiting 6 months to a year before introducing one...
