Time to buy a bottle of coral rx

I do dip my corals in coralrx one shot but this one somehow got past it. Read that they hide inside the polyp itself and hence the dip might not get to them.

Go look at your zoas with a flashlight a few hrs after all your main lights go out.I had 15 lbs rock covered in zoas yrs. ago.They just were slowly disappering and found out i had those disgusting spiders.Bugs of any kind don't bother me...but zoa spiders creep me out.

Thanks for the heads up :) I plan on doing that tonight.

That thing was disgusting looking :O Just doesn't go with the reefs! Even anglers are prettier than that thing!
