In bleaching, the coral loses it zoanthelle, in RTN, the tissue actually comes off of the skeleton. Bleaching can be fatal but isn't always, but RTN is fatal 100% of the time (assuming the whole colony RTN's). Also, it seems that RTN can spread to other corals as well.

Sean, pull one out and smell it. If it doesn't smell like acro, it lost it's tissue. If it stinks. it's bleached and can come back.

IMHO one of the triggers for RTN or STN is alkalinity that gets out of whack. I have experienced this many times when the alkalinty rises or drops unexpectantly.

Did it start losing color from the bottom up or the top down? RTN is usually a bottom up kinda ailment.

I never really got to see. On one coral it looks like bottom up on the other it kinda faded away brown the white.
