On the hunt! We want your hitchiker pictures!


New member
We are always searching for images for our hitchiker FAQ and are looking for pictures of:

-things we don't have on the pages
-clearer/better pictures of those we have descriptions for
-more specific IDs or more information on each critter

>pest algaes
>pest anemones
>anything else that happened to come in on your rock that you have a good picture of!

If you have any of these types of images, and you are willing to have us use them in our expanded HHFAQ, please post them here or email to: wade@reefs.org (we will credit the photographer of course).

Found this guy attached to the bottom of one of my live rocks. Dunno what it is, but I'm guessing it's a cirolanid idopod. That would be a bad thing. He's in QT until I can get a positive ID.

We are still collecting images from anyone who has images that show good detail of any hitchhikers you happen to find in your tank.

Please visit the new website and the new hhfaq layout. Its still under construction, but its filling in nicely. If you have recommendations or would like to add more detail to the faq, please let me know!

Very very hard to tell from your pictures, but based on the description, its likely the filaments from various worms that are being extended to capture the floating debris that stirring your sandbed produces.

People used to stir their sand alot, to feed corals and inverts, although that isn't too common anymore.

There are spiders that can live around the water, but they are freshwater only (afaik) and they live outside in the air, they just capture air along their hairs to breath while underneath for short periods.

Based on the speed at which that spider is moving, its not in your tank surrounded by water. You positive its not outside someplace thinking it can make a meal of the 'pods you have inside?

True sea spiders do not have thick bodies, they are very very thin and stick-like and are very odd critters altogether different than what you are showing.

If you watch the video carefully 3/4 through it moves a sand grain inside my tank when it moved. As for the speed it is moving at, I have smaller isopods that move just as fast. The video is taken through a microscope at about 600x mag. If it is a spider that hunts it would have to be faster then it's prey. Maybe you could argue that an isopod inside got spooked by the sight of it, and it moved the sand grain in retreat. But it doesn't appear that way to my eyes.

I have the pictures, some questions:
- What is preferable size in pixels?
- I should post them in this thread, right?
- Will they become the property of the reefs.org, or I can continue to keep them at Photobucket and post on the forums?
