Someone talk me out of this (choco. chip star vs. mushrooms)

[Delphinus]

Ok, I've been tempted to try this for soooo long. Set up a 10gal or something simple, little aquaclear for filtration and a heater. Home for a chocolate chip star. Anytime I've had it up to the whazoo with a mushroom infested rock, I put the rock into my "cleaning tank" and let the star do its thing.

My only question is, what do I do with the star during the "slack" periods I don't have a rock to clean. Sounds like they'll eat pretty much anything they can get ahold of? So maybe just a few pieces of mysis or krill every now and again?

What's the pitfall here? Should I not do it?

It's just an idea. I know it sounds harsh but after 4 or 5 years and starting off with .. one .. single .. purple mushroom that thing has spawned thousands upon thousands of descendents. They kill any SPS they touch, so it's not like they're perfectly innocent. I don't mind them in small numbers it's just when I have wall-to-wall mushrooms and they kill off neighbouring corals that I spent money or traded to acquire (oh yeah .. they'll take out zoos too, BTW), that I start to dream of some way of keeping these buggers under control.
