I had a few corals start to die on me.Well one started to die and i was trying to save it but then anohter one started to die.I was just wondering if a coral starts to die does it relase anything that could mess with the other corals?That all i realy need to know because if anything else gets sick then i want to know if i can try to save it are just throw it away.Im out like my 80$ pearl bubble coral
