I am not sure what these spots are but if they are flatworms, if I dip just this coral, then I kill all the flatworms instead of them dying in my tank. However, the goni will pull in when it's touched and stayed balled up for a long time. So how do these worms die if the arms are pulled inside its skeleton while being treated?
Would it be better to use flatworm exit and just do the whole tank? I was trying to avoid them getting in the tank after dying and just spot treat the goni but if the goni balls up, there is no release for the dead worms...
