another anenome question

[Seamonkey]

:? I now have a name to my anenome (macrodactyla doreensis)Thanks. This is more a query than a concern.
It took about 3 weeks for my common clowns to become interested in the anenome, once they decided they like it, they really have not been away from the tenticles for more than 20 seconds - not that I sit around all day staring into my tank...
After a few days I notice a new behaviour, don't know if it was both clowns, or just one, as they are pretty much identical in size, but it appeared they were sucking ? on the ends of the tenticles really, this went on for a while periodically, not all the time, and now 2-3 months later I realize that this does not happen at all. I'm not even sure how long it went on for. Is this a aclimatization respose, anyone had this happen with their fishies.
