New SPS losing flesh

[OsiViper]

Ok I got a bunch of SPS Frags in yesterday.
Got some Pocillopora, Stylo, Digi, etc.

I had a green slimer that I guess was extremely stressed during shipping and it pretty much had an overnight RTN and was bare this morning. Most of the frags are doing fine, but a few are showing patches of missing flesh, some in the middle some in the tips. It doesn't appear to be progressing rapidly at all.

Is it normal for some of them to lose flesh in shipping if they got banged up or is this probably STN? And if so should I try to frag the pieces or just watch and see?

Those are all very hardy corals. What are ur water parameters and alk. How did u acclimate? Oh btw pocc and stylo may look like pieces are missing but polyps come out when settled in

 

[OsiViper]

Alk is about 9, calcium 450, mag 1400, Nitrate 2-3, Phos 0, pH about 7.9-8 and salinity is 1.026

How did u acclimate, shipping is stressful and acclumatio, needs to be slow because of temp variation. Wait and see, fragging will stress them, if there is polyps it will grow back

Bags were floated for 30 minutes and then they were dripped for another 30 or so, and then dipped before being placed in tank

they're stressed and in the bags too long. keep them in a low light, medium flow area and hope for the best. some will recover.

Sounds good, although you don't need to drip a climate like you would a fish, just temp acclimate and pop them in.

I would wait and see what happens could just be stress. Where are these located in your tank, I'd put them low. I bleached a slimmer once by not light acclimating it.

I had them on the sand for a bit but moved them up to the rocks. They were much higher in the water under a brighter light where they came from.

Ya but they were stressed when removed. Hitting them with your light high in the tank will likely bleach them out. It's what happened to my slimer. It was only out of the LFS tank for 45 minutes. I placed it high in my tank and it bleached in a few hours.

Good luck

They were on the sand bed for about 2 days. And the slimer didn't bleach. It lost all its flesh and polyps.

Basically it sounds like your acros have RTN from shipping stress as you noted. To try to save them I'd do iodine dips every day for 30 minutes until the RTN can be stopped. There's no point in waiting to see if they recover. RTN can kill your coral in 1 day and can spread to all other including healthy acros/ montis. Fragging acros when they have RTN puts them under more stress. Sometimes you can save a few pieces but I'd first go ahead and dip to kill the bacteria and ciliates which are attacking your acros. Straight after a dip you may be able to frag some pieces and have greater success because the majority of the bacteria and ciliates may have been killed by the dip.
