What are your parameters, do you carbon dose and how often are you doing WC's

 

[ninjamyst]

have you tried dipping them? maybe zoa pox?

nothing left to dip should i dip rocks they were on? was thinking of waiting a couple of months before adding any in case its a bug which hopefully will die off

I had a rabbit fish wipe out a colony of bam bams in two days.
He's gone.

I had a snail that looked like a nerite. I had a colony of a100 or so pink and golds that were declining. I realized the snail wasn't leaving the area and suspected it. got rid of it and my colony has since grown to over 200. I had never heard of them ever doing damage to zoas.
