Anemone / Captive clown question

[Coralgurl]

I've had 2 sets of clowns that have looked for hosts. My first 2 (black and white with the orange fins...sorry for not knowing their names), started trying to host my bubble coral. Bought a seabae nem and they were in it within 10 mins - I unfortunately lost the clowns and nem. My current clowns are seabae clowns and they are hosting my frogspawn along with my porcelain crab. Recently, I've noticed them wiggling in my brain coral. Once they move to the bigger tank, I will try another anenome for them. One thing I've noticed with these clowns is how territorial they are over the frogspawn and tend to only hang out by it. The original clown we had (jumped), didn't host anything and was quite active in the tank.
