Bubble Anemone,Crab,Percula

Hello,
Last week-end I bought a very nice bubble anemone with a enemone
crab, I had 2 percula or false percula (not sure witch but love them).
Yesterday when I came home the perculas where in the anemone with the
crab, the crab does not seem to mind but one of the percula is trying
to get ride of him. Do I give them time to talk it out and realise
that the anemone is big enough for 3 or is it better to move the crab
to another anemene. If you suggest to move the crab, how do I do this?
Bare hand, with a cup.....?


Thanks
