Would frag off the tips that have algae on them. I have lost a few colonies by not stopping the algae before it covered the entire coral. If the clipped tips show any coral life, you could always let them heal and see if you get some frags out of them.
Agreed. Will probably head up that way to do some collecting of my own when they kick off. In the mean time, will start construction on the expansion to my shark pond. Going from 5000 gallons to about 8000 gallons when all said and done. My Japanese leopards will appreciate the extra room!
