Whats this growing on my frogspawn?

I thought it was a vermetid snail but I dont think so. I doubt its a new head since its too small. Any ideas? Ive only just spotted that today. The coral seems to be doing as usual, it does not seem affected by whatever that is. I ams talking about the lump to its right

Fuzzy picture so I cant really tell, you talking about that purple bit on the right hand side?

Probably a vermetid snail, some can get rather big- up to 1/4 internal diameter for their shell...

I need a clearer pic. The base looks like a vermatid and the head of it looks like a new head of the coral lol.

Looks like a vermetid snail to me. Mine have reddish/purple color to them....that's the snail inside. If it was a tiny new coral head it would have little tentacles like the mother.

If it puts out a mucous net at feeding then it is probably a vermetid.
