asterina stars eating zoas?

[gregzz4]

My harlequin pair did a number on my red star and it passed

My pair have since been re-homed to another member who had an asterina outbreak

As far as the OP thread goes, I guess I've been lucky. I had a huge outbreak of asterinas last year and they never touched my zoos or palys. I had maybe a hundred visible stars before I bought my harlequins.
In retrospect I should have got my params in check, not kill off the stars.
