Try this...after the light goes off and your clown is ready to sleep, get your net and slowly guide your clown towards the anemone until part of its body hits the tentacles. Sooner or later when your clown realized its fun hanging out there, it will never leave.
This is what I did. I put in the BTA with my Ocellaris that i had for over 2 years at the time. I positioned it close to where the clowns slept at night. Then I taped pictures of clowns hosting anemones around the area that the BTA was. It took around 2 1/2-3 months but eventually the figured it out. Then the BTA got sucked into the vortech and now the clowns host my giant torch coral (even better IMO). I think once you get a pair of ocellaris to host a nem for the first time they will be more willing to host corals after wards if the nem is removed.
It's just a pain to get them to start hosting if they've never done it before.
Are they tank raised or wild caught clowns? Tank raised are more likely to go into an anemone than ones from the wild that are not used to a BTA (not their natural anemone host) I had wild caught ocellaris that never took to my BTA even after keeping them in a colander in close quarters with the BTA.
Couple of things;
Forcing a clown to be hosted is a good way to get your clown eaten.
Tank raised/wild caught has nothing to do with it, the issue is that the 2 most common tank raised clowns are O's and percs. The most commonly kept anemone is an E. quadricolor, neither of those combos are a natural combo, there in lies the issue.
Time is the best means of having your clowns hosted when using a non-natural combo.
Push them on in and they'll find it
And it's the anemone that HOSTS the clown, not the other way around![]()
