Hi, this is my first post on this forum…
In October 2024 I got for 20 dollars aprox a hellfire torch, it was very cheap because it was not opening fully, the Store owner thought it was because a melanorus wrasse was picking at it, as well as other corals.
So I took it home with a splattered hammer from the same tank (the hammer was and still is completely healthy), a couple of weeks passed and I notice little hairs on the skeleton on the torch, so started to investigate but could not ID them, so no action was taken thinking they were harmless.
But yesterday I encountered a post in a facebook group were a Frogspawn had the same kind of hairs on the skeleton, went through the comment section and someone mentioned the name of “coral boring spionid worms”, so I looked for pics of them on Google and found out thats what is on my torch, I investigated more and found they stop coral growth and make them retract their polyps, and that is likely the cause why my torch has not openned fully since I bought It.
I don’t think is a parameter issue because everything else in the tank is doing OK (acros, hammers, montis, zoas, stylos, gonis, etc.)
I have only found that the only thing that kills them is an ivermectin dip, but the doses on internet are for acros, I haven’t been able to find a dose for torches, anyone has the quantity for such dose? Or what other methods can I use to get rid of them? I yesterday tried to scrape them of with a blade but they are still there today
