Percula clow fish habitation

[Manon]

I have two clown fish who were living in a hammer coral until recently when it started to die for unknown reasons at this point. I'm worried about my clowns but don't want to put an anemony in the tank b/c I have a lot of coral in it. What would you guys suggest I do?? I could get another hammer coral but after loosing this expensive piece of coral I'm a little worried!!

Thanks for your help!! Manon
