What’s growing on my frogspawn

[Nfd552]

Have a growth on this one. I glued the hole shut for week, then took the glue off and I’m pretty sure it smells dead. Dipped it afterwards...If u notice the flesh of my coral, it should be dark, but it’s 3/4 bleached looking. Any help IDing?

A very large vermetid snail. If you glued it shut and it's dead, you can try scraping it off

That’s what i thought, it was just huge compared to what I’ve seen. I didn’t think anything of the coral until i noticed the color change...I tried scraping it off initially, but that thing is on there lol
