Are there any special ways to acclamate clowns/anenomes to get them to form a relationship? I mean things like putting them in a QT tank together, once they decide to live there move the whole setup into my main tank? Or after acclamating and before putting them into the tank, put the clowns into the bag with the anenome?
IME there is no reliable way to get clowns to host in an offered anemone, other than patience. Particularly since it is often not practical to pair the common species of clowns with the exact species of anemone they would choose in nature. I have a hadonni anemone with Ocellaris clowns; the big one (presumably becoming the female) accepted the anemone after 6-8 months. Of the 3 remaining juvenile clowns, I suspect one will eventually team up with the lady clown & her anemone but it has been over a year now, and they are in no hurry.
