![]() I just picked up a nice multicolor acro colony yesterday and today noticed its starting to rtn! Efffff what can I do? I hear super glue over the affected area? Frag off what is unaffected? Or is it doomed? It's just a small spot so far but I don't want to lose this piece. Ughh I hate sps now.

![]() RTN is caused by some sort of stress to the coral... figure out what that stress is and how to fix it and it should stop on it's own. Sometimes just the move and change in water can start the RTN. trimming or crazy glue might isolate the dead tissue, but if the stressor remains it will just kill the remainder of the coral. What else can you tell us about what might be stressing it out?

Salinity 1.024 Ca420 Mag1350 Alk9 0 nitrates ammonia etc. I clipped off the rtn area and fragged a piece that looked good, then glued over the affect cutting site I hope this works.. I also move it back to the sandbed at the front of the tank, whch was where it was in the tank purchased from.

![]() I would say you are doing the right thing so far. Other things to check: make sure water flow is appropriate and there are no parasites on it. Good luck,
Dan

![]() Water flow is pretty good IMO. I have a dozen other sps frags I've had for 6 months +/- with no problems no parasites I can see. Mind you its tough to see them sometimes and it was fipped while acclimating. The lfs had it for a good month before I bought it as I've been eyeing it up. So I don't think it has anything to do with it being transferred to quickly.

![]() If I see RTN I always make a frag that is at least 1 cm away from the affect tissue and put it in a different spot in the tank. I have been able to stop RTN on established corals, but I have never been able to stop it on new corals. In the case of new corals there isn't much you can do that I know of. STN is much easier to stop since you have a much bigger time frame.
Are you sure it is RTN and not STN? With RTN you will be able to see the skin sloughing off and it spreads rapidly, like 4-6" per day. STN is much slower so you don't usually see the skin sloughing, just peeling up at the very edge of the affected area. STN can be as slow as 1" per month or so. Good question. I have had horrible luck/experiences with iodine-based dips. CoralRx seems to be effective and well-tolerated by all corals that I've used it on. |

![]() Yes its definitely rtn I've had it before. As for the dip, maybe 10 minutes as per the directions.
Edit dipped in coralrx

![]() The piece I fragged off was on the next branch over but appeared unaffected, should I cut more off for saving purposes or leave it be? I definitely won't be buying colonies anymore. I only bought I cause its a beautiful piece and I hate waiting for frags to grow out. Big mistake I think.
