Strange looking worm

[kevindo123]

It has two pointing things that goes in and out of its head.

Found it on my glass its about 1 to 2 mm long.

Looks like a nudibranch of some sort. Keep an eye on your corals specifically Zoas and montis. Some specifically eat certain types of corals with those two being most common. If they are infact zoa or monti eating nudis they will normally be camouflaged to blend in with what they are eating.

I'd remove them just to be safe while you know where they are. It's a nudibranch, most are specialized feeders of coral, sponges, and other things we like to keep.

Might be Vayssierea felis . Which eat Spirobid worms (the teeny circular feather worms, usually like to grow in overflows). Here is my local group and I chatting about them- http://wamas.org/forums/topic/74915-squishies-nudibranchs/
