Hurt my Zoa's

[alicel]

This morning I was scrubbing hair algae off of my rock with a toothbrush. The location where I scrubbed was right next to my zoas and the toothbrush brushed up against a few of them and broke them off/basically killed a few polyps. I know...rookie mistake. Won't happen again.
Will this harm my tank at all??
Will it cause any damage or upset to the rest of the zoa's.
(Total, my "zoa garden" is only about 2 1/2 x 1 inches.)

If you knocked off some polyps you can use superglue gel and glue them back to the small rock and place back into the tank. They may or may not make it. The other will close for a while but should open back up.
