what is this white worm thing???

It is about 2" long and had "hair" on top of it.

Looks like a nudibranch to me.

Looks like Tritoiopsis sp. Have you bought any new soft corals recently? These are hitchhikers that are often predatory in regards to softies.

I have had some soft coral, but most have died...

Do need to worry about this? Do I need to remove it? Or now do I have a new inhabitant to my tank?

If it is what I think it is, it may be the cause of the demise of your corals! I would consider removing it.

It almost looks like this. According to Liveaquaria they are reef safe but we all know how that goes. Check out this link.

I dont know. Maybe not. Upon further review yours looks feathery whereas this one is more ruffled. Maybe someone else can help.

I thought I already had helped! Refer to previous posts...
