Hosting your clown
Is your clown tank raised or from the sea? My tomato knew exactly what to do in about three days being from the sea (having a moray eel, a lionfish and a shark may have influenced him to nest as well - lol). If he is tank raised, he may never nest - especially if it is not an anemone that they would normally settle into. One thing I have heard may be helpful is to laminate a small picture of a clownfish and place it into your anemone so the clown knows where to go. I have never tried it, but a friend of mine got his percula into a bubble that way. Good luck.
