Sudden RTN

[carpetlover]

I woke up to this morning to everyone le dreaded scene. RTN. This seems to be localised, only on a frag I had just put in yesterday, and everything else looks fine. Should I take it out/what should I do?

Take it out, dip it. Check for parasites (aefw, red bugs, black bugs,) clip the top try to salvage whatever is left of the frag and re glue it. Think back to any possible changes that you may have to your system. Or any recent parameter swings and such.

I just acclimated it yesterday. I am running 3.5°c higher than its last system. I don’t see any flatworms or bugs. Paras are ok and all other sps has good polyp extension

If it's a new one and everything else looks fine, it might of just not take to the system temp like you said. I would prob just count it as a loss hope the remaining skin will heal. look at the positive, more space for another acro lol (hope it wasn't a pricey stick)

All to familiar with this, judging from the lack of encrusting this must have been fragged by the lfs or dealer quite recently. Based on my experience newly fragged Acros always have a higher risk of RTN upon introduction. Fragging is traumatic and stressful to corals. Like others have also pointed out, it might be due to to pests as well as the coral not acclimating well. Ultimately, you can’t do much but just let it be and hope for the best. Though, judging from the pictures the frag is most likely not going to make it.

What you could try is to try to ramp up flow towards the bottom or if you happen to have frag racks, put the frag on the frag rack. Your frag rack shouldn’t be too high up and somewhere midway in height. I have had acros that were RTN due to shipping stress and I do notice that having stronger turbulent flow (meaning the flow has to hit from all directions in a sort of rolling motion) increases the chance for the frag to recover. Best of luck.

Thanks much for the input. Unfortunately it’s pretty much totally white. Everything else is fine, even the others I acclimated that day. I suppose it won’t recover, and I lll chalk it up as a loss
