My wife is still trying to find a way for me to watch America's Next Top Model. I still refuse even though the host is hot.
In all seriousness there are ways that help but I will not tell you. I don't believe they are natural and they cause stress on both species and that isn't cool. Just keep your fingers crossed for it to occur on its own.
I was no help so I apologize.
I heard (and tried) cut out a picture of a clownfish and tape it to the glass near the anemone. It is suposed to make the clown want ro retreat into the anemone for safety. All it did was tick off my maroon.
You could try it, can't hurt. You can't force it, you just have to let nature take it's course.
Chances are very good w/maroon and bta, it's natural host. BTW it took mine a few weeks to host, good luck!
I have to agree with Jerry, if it's gonna happen, then it's gotta happen on it's own.
Hosting anemones are;
Bubbletip-(Heteractis quadricolor)
Maroon or Ritteri-(Heteractis Magnifica)
LTA-(Macrodactyla doreensis)
