Hi
My Zoa colony has been disappearing. today I found these large white balls on the Underside of the rock ( not on top w the colony). they look much too large for Zoa pox. they are nowhere else in the tank. any ideas at all? please help- this is my first attempt at keeping zoas. thank you so much for any input or ideas!
