    Question white tree like thing - need ID

    Hi

    I need an ID for this white tree like thing that is growing everywhere on rocks and powerheads. It is white, branching, really thin, and at the tips it has a polyp like tip. It's really thin so it does wave around in the current. And the tip can catch little things like cyclopeeze. I've been reading up on hydroids and stuff like that. I think that is what it is but have not found pictures that look like what I have. I'm hoping it is not bad stuff....hope someone here knows for sure whether it is a bad boy hydroid or not.

    Thanks.
    Here's a pic. Kind blurry but the best that I can do.
    thanks.
