 I am having a hard time identifying this stuff that is growing on my frag of zoanthids. Most of the time that means that it is a pest. Can anyone identify this for me. It looks almost like a very thin chaeto because it is stiff to the touch. The Frag is question is in QT right now. Should I just throw it away? Treatments? I have never had bryopsys but each filament is singular not feathery  or fuzzy

If I'm right, it's common name is Sea Brush algae, though it's not too common in aquariums. I believe it's closely related to Valonia (Bubble Algae). Emerald Crabs are good for cleaning Valonia, though a fish is often better when the Sea Brush gets this long.

A nice red variety also appears in our tanks.

Those frags have several types of Nuisance algae. They could use a good cleaning by some herbivores. Good herbivores are Snails and plenty of them, Hermits, Emerald Crabs, Tangs, Rabbitfish and Urchins. If recently purchased from another hobbyist, that person needs to know that algae covered frags are unacceptable. 

Algae problems are the most common problem in this hobby. When hobbyists learn the value of keeping lots more herbivores(plant eaters) than carnivores(meat eaters), their tanks look and operate a lot better. Resist the urge to buy a Wrasse, a Royal Gramma, a Pseudochromis, a Hawkfish, etc. and buy herbivores instead. Carnivores eat up the little bugs(Copepods and Amphipods) that should be thriving in our tanks. These bugs eat new sprouts/nubs of nuisance algae before we can see them, before they become a nuisance.

The quickest way to speed up the cleaning job is to use a toothbrush on all those frags. Zoanthids and Palythoa especially like a good brushing. It seems to invigorate them. But the brushing won't get the Sea Brush. It doesn't hurt to manually pull off any strands of Sea Brush. To be honest, it's a useful algae in the right situation. Can you see the Sea Brush in the pic below?
