Bugs!!

[Aquattro]

Jon, I think Wendell's idea of epsom salt baths might be better for flatworms. When you get a frag of acro, you'll be able to see the bugs with a magnifying glass...if they're present, then Iodine is the only thing that kills them (so far). I would recommend putting any new frag in some tank water in a separate contaier for a visual inspection before transferring it to the tank.
Also, when you get a frag with flatworms, they are on the base/rock/plug, not the coral. I break all new frags off the base as soon as I get them. Remount to your own plug, and you should be safe. I'd also prefer to have flatworms over these bugs!!
