contagious sps disease?

[Corbin]

So i had one acro start melting on me, i fragged the healthy parts (the flesh melted too anyways), when i noticed it was starting to melt/bleach out, i moved it up to the top of the tank near more flow, moving a frag of monti cap, the acro died out completely, the frags too. i moved the Monti cap back where the acro was and it started melting too, and then it got moved and was resting up against another SPS colony and now its starting to bleach out slowly, its like a slow flesh eating disease, passing along by contact, and slowly killing off the whole coral advancing along it over a few hours or a couple days.
none of the sps that hasnt touched these "infected" corals are doing bad, they're looking great actually....

Not to concerned tbh, just curious


im guessing RTN?
