I just added my first frags to my tank and I am not sure how to go about attaching them to the rocks....Is someone out there that can give me instructions?

Also I saw some black stringy stuff coming out of the middle of a couple of my frags and was curious as to what it is...
Thanks for the help

It depends on what you got. Let us know, and we'll tell you how to mount them :)

one inch square zoanthids with about 10 polyps on each tile square. we have tonga branch and live rock in the tank and the tank is 180 gallons.

Are the zoas attached to a piece of rubble? Either way, jus get yourself some superglue gel (not the liquid), apply a bit to the zoas, or the piece of rock they're attached to and glue them in place. You'll have to hold them in place for maybe 30 seconds or so.

You can do either. The zoas will overgrow the tile soon and you won't notice it, but you certainly can take a razor blade and cut them off. Just cut as close to the tile as you can, more like scraping them off, and you can glue the mat they grow on directly to the rock. The stringy stuff is most likely zoa poop.

Thanks for all your help, been at this a couple months now and have questions once in a while.

No problem. Welcome to TR.
