tarhull,
I happened to see one crawl out from underneath. You can try a coral disinfectant. They are iodine based, and helps in these types of situations. They will need good circulation and light. Do the dip every couple days, or every day...follow the directions on the bottle.
bj,
I will see what I can do...I will have to frag them out first. Give me a couple weeks to grow them out some more...
