So i went away for a weekend when i came back found my purple chalice under my raja rampage chalice. They both were stinging each other but my raja rampage had skeleton showing but in a week it bounced back like nothing happened. Now my purple chalice at first had almost no skeleton showing at all and now over time its ben loosing its tissue. Don't know if just cutting the dead stuff off will be enough or should i also dip it i just don't won't to lose the hole coral?
