Slime on Blue Acro

[Nicmar]

I have some small bits under this blue acro that have had slime on it for about a week now. Any ideas on what is causing this?

Can't see it can you show a better picture?

Sorry using my iphone.

How often does it slime? Constantly for the last week? I notice that after I feed the corals my acros slime like crazy.

It could be a hermit crab picking.

It has been sliming for around a week in places.
My guess is either chemical warfare from the coral very close to it or due to a kh spike that happened around the same time. kh is now stable. No other coral is affected which is strange.

I don't have any that are meant to be there. Perhaps a hitch hiker.
