Branching translucent hitchhikers on live rock

[Michael Hughes]

Any ideas what these are? Very small and mostly translucent, so this is the best photo I could get.

Could be zanclea hydroids.
Tiger cowrie snails are supposed to be a natural predator.

Great photo! I believe these hiked in from the TBS farm? In an effort to document various Live Rock hikers would you mind sharing the photo with us, as well as monitor these - noting if they increase or decrease? From our knowledge, they eventually disappear. Not sure if that is because of a sampling shrimp or lack of nutrition.

Thanks! Yes, I'd be happy to share it with you. Just sent it via PM. These did come in on TBS rock along with some great corals, macroalgae, and other cool stuff. I very much appreciate what you guys do and I'm happy to support you!

I only noticed them once and snapped a quick photo. I was holding the rock at the time - it was the only way to get a decent look at them due to the lack of contrast. I'll take a closer look when lights are on this weekend to see if any are left. They are truly tiny.

The app doesn't forward you to the correct post sometimes so I include the page and post number in my message very often. The link is the direct link to the post so it should work in a browser though
