Acro pest please help

[spsfan]

I noticed today this barnacle look alike on a tenuis.
It seems to grow within the coral skeleton and make a hole in them.
Does anyone have any idea how to treat them ? Do you know what type of acro they target ?

Sorry. Double post.

I'm not sure what they are, but I do know I've lost 3 wild collected colonies over the past year and all 3 of them had those. There is no doubt that it could've been a coincidence, as these were the only wild colonies I've ever purchased. My tank and my skill level may just not be up to par for wild colonies.
I purchased the 3 colonies at different times from different vendors.
Another note, these have been the only colonies I've lost. My maricultured and aquacultured ones have always done great. I'm guessing it was more my fault than the barnacle looking pest.

Thanks for the reply.
So they did not "migrate" to another coral. Do you remember what type of corals they infected ?
Also how long ago did it happen ?
PS I really hope that it was your experience level but i do not think so.

Just found this. Looks like I was right. I'm just not ready for wild colonies.
It's been in the last 6 months that I had the corals with them. I have not seen any on my other corals so it doesn't look like they migrated around to much.

Thank you for your help and effort.

Yes those are barnacles. They usually come in wild colonies.
