Red Bugs?

[NewbReefer]

Hey all, So The other day I noticed these red, nudibranch-y bugs crawling all over my goniopora... i freshwater dipped it, and they all seemed fall off of it, and the coral SEEMS to be ok...but now i see that there are some on my mushrooms now too... wtf are these things? Ive read about Acro red bugs, but not really any other types. How concerned should i be? Will these eat/destroy my lps's (frogspawn, brain, candycane, doughnut???) i havent added anything new in my tank for quite a while, i just got back home from being out of town and noticed these things....:icon_eek:

Are they flat if so could be flatworms some are reddish in color.

A pic would be great...
But that's what it sounds like.

If so read up on them they can be a problem in large proportions....
