Need ID on this one

I am not quite sure what this is but I saw it for the very first the other day. It kind of looks like a snail without a shell. Its green in color with a red spot at what appears to be the rear. It creeps along real slow on the glass. It has no spike looking things like all the nudibranc I have seen do.

Is this a baby nudibranc, flat worm or what?

 

looks like a flat worm

 

flatworm, if you value your corals get rid of it.

Ya flat worm, they are hard to get rid of, better suck the sucker out

 

Never seen a green flatworm, only pinkish-red ones. Thanks for the pics

 

flatworm exit works awsome.
