emerald crab is a potential, not necessarily the cause. I have seen mine scrape away at coral flesh, but never hermits.
Thanks. I do not have emeralds, just hermits.
I guess it might be water quality. For awhile I have been in the process of changing salts and I was mixing two salts in varying proportions so maybe I have been creating too much change. I am now using just one salt so i hope this will make things more stable.
