Nudibraches

[Jewel]

I've got them floating around my tank, I've had the Bergia Nudibraches in the past and thought that this was a good thing, great for Apstatia which I do have poping up here and there,

Now I'm thinking they may be the culprit for my Frogspawn not opening, what do you think?

I am pretty sure Bergia only eat aiptasia and will starve without it but there are all sorts of nudi's most are not welcome.
