Well, I don't technically need an ID, but I just read about sprinkling table salt on them to remove it. I have one smack dab in the middle of my zoa frag and I don't want to kalk it in fear of hurting the zoas. Could a few grains of carefully placed salt get rid of the bugger without hurting my zoas? Also, will the salt kill it or just make it let go? I'd kinda like to save it and put it in the mantis tank, its a pretty one with a bright green center. I can't get a pic for you guys, but it's definitely not a zoa and the ones around it are always closed up from being stung.
