cup coral shedding?

[bv_reefer]

oo sorry no pics so far but speaking of defense mechanism does that mean he's having a chemical war with a nearby coral, if this helps the corals in his proximity are a green monti cap frag, kenya tree colony, xenia, finger leather colony, and finger leather frag, i noticed the same slime on my monti cap frag the same day, i don't know if thats from the cup coral or from the monti frag itself. today he's better not producing slime anymore.
