" -The first is that my favorite blue zoos have 95% dissappeared! I don't know why because all of the other zoos in the tank are fine. I've ruled out predators because the colony sits right beside another type that are thriving, and I find it hard to believe that a predator would be picky about the color of zoo they would eat. Am I wrong?"
- they can be... I've noticed predators to prefer color as have another zoo owners. but I wouldn't blame it on that, yet.. not when there are other more likely reasons. Doesn't hurt to check for snails tho.
- Could be lighting. Some zoos prefer high light, some do better with lower light. Have you moved them recently?
- Any slime? Any soft zoos?
- Are they disappearing at random locations, all at once or from one side to the other?
-I'd recommend fragging 2 frags now if you can.. one you give to a friend after you've zoo dipped it... and one you put in another location... Leave the colony where it is and hope it survives.
- Are there any other corals touching it, LPS, leather?
- Are there any feather dusters, spaghetti or bristle arounds irritating them?
- Any aptasia or Mojano stinging them?
