If you can, scrape underneath them removing a thin layer of rock. Then you can glue them on a new rock. The new yellow polyp rock could be traded to a LFS for store credit. They are fast growers, but IMO manageable. I have done the above. I have also done kalk paste and have covered them with super glue gel. I try to always save them when possible. It takes a little work, but I can usually find a home for almost all my unwanted frags and even make a few $ sometimes.
