been finding cuts in my zoo's. What could be causing this? I had some blue halo's that were doing great and now it seems like a couple of them have small cuts just below the head of them. I dont want to lose any more zoo' what is it a crab or something?

do you have a rouge decorator crab? i had one that took out about a colony before I finally caught him.

i get up really early long before the lights come on. I've never seen anything unusual even with a red light. thats what boggles my mind.

Check at 3 am.
Creatures know when the lights are about to turn on (sunrise) and will be hiding LONG before then.

You need a late night session to really see what's going on in the tank. Recently I had a frag that kept getting knocked over and a 2:30 session revealed I had a baby urchin playing earth mover at night. NEVER see him in the day just LATE at night.

I would check for nudis.

Go to the zoanthid forum here and theres alot of info about zoa eating nudis.

if you have cuts in your zoo's dont handle em with cuts in your hands, just a warning many are highly toxic!
