I know one of my clowns hosted it but it left it a few days afterCondy Anemone are not considered hosting Anemone. Occasionally they will host a fish but it's not common.
When I started a population I had a little piece of live rock and for hiding I got them chaetomorpha (spaghetti algae) but I don't know if they eat chaeto but phyto two will get them breeding and eating really fast
I still doubt it because one was on the floor and the water from the pre filter is at least 3 to 4 inches from the top and it would seem that he was pretty healthy
