True. *SIGH*
What is the best course of action then for my specific situation?
I got rid of them really easy. I boiled some water on the stove, took a 10cc syringe and sucked it up then squirted it directly on them and melted them. I then tried to suck out any ruminants with the empty syringe. Eventually I was able to get them all but it took time as I had to get the new ones as they popped up.
Even if you replace the rock, you have larva in the water. Hence how they pop up in new places.
So next time you add a coral, some more larva could come in and you start all over. Can't be replacing rock all the time.
