Coral frags bleached in just one day?

[gatorcream]

I just got some corals in the mail from topshelfaquatics. They sent in a sheet saying their flow and lighting preferences too. Both of the corals require medium to high lighting.
Anyways, I got a Christmas mirabilis and a birds nest coral, and they seem to have bleached in just 1 day from being in my tank? I’m super confused. I’ve got 1 nicrew 100 watt light, raised up 8 inches above the tank. The mirabilis went from pink and red to bone white, even though it’s in the same general location as a hammer coral, and an elegance coral that are thriving receiving that amount of light. (None of them are close enough to be injuring eachother, I’m just talking about the light intensity/par).
And my birds nest coral is currently sitting at the bottom because I haven’t found a nice place for it yet, but also has turned white. The bottom gets enough light so that zoas, xenias, gsp, bubble tips anemones, and cloves are all very happy.
I’m just confused. My parameters are stable, I haven’t had any weird spikes lately. Can corals bleach from lack of light? I just don’t know what’s going on.

Lot of reasons corals can bleach. It might or might not be your fault. Bad shipping or just bad luck.

Picture?

Picture?

Ignore the algae on the glass in the pic with the birds nest lol, it’s a hard area to reach

What are your phosphate, alkalinity, salinity, and temperature numbers compared to TSA's? My guess is your alk is way lower or way higher than theirs.

EDIT: also, did you dip before placing them in the tank. That's an added stressor.

Are you sure it’s bleached and not tissue necrosis and what you are seeing is the corals skeleton.

 

[V A R I A N T]

The top photo, sorry, that’s not bleaching. That’s rapid tissue necrosis (RTN). That coral is dead. The birds nest looks bleached and might pull through.

I agree with the first picture that it necrosis but if I’m seeing it right the birdsnest still has polyp extension.

smoked them Ide reach out to vendor wouldn’t hurt

I think so too, the birds nest still looks like it’s got polyps all around it, they’re just not green and blue like they were supposed to. Is there any hope that they can get better or are they pretty much goners?

The mirabilis which is the top photo still has some red at the ends of the skeleton too

With a tiny bit of tissue left on the mirabilis it can recover but most likely won’t. If everything in your tank is stable the birdsnest will likely recover.

What did they look like coming out of the shipping box? Temperature stress? I noticed you are in Michigan.

I don’t think there was temperature stress, I picked them up at a mail facility instead of having shipped to my house and be on a cold truck. They looked more colorful but closed. I acclimated for about 12 hours then dipped with polyp lab reef primer

What causes this? Is there maybe something in my tank or was it the sudden lighting?

 

[amazongb]

What are you parameters? I usually try to keep my alk/ca and temp close to the coral vendor I use. New corals sit on the frag rack for a few days before mounting.. low light won't kill them quickly, whereas too much will (imo and experience).

It’s hard to say. If all of your parameters are in range and stable then it could be shipping stress. Are these your first sps?

 

[Hurricane Aquatics]

First need to know your parameters. If u had to guess, it almost looks like polyp bailout from your tank having very high alk/phosphates. Can you list your parameters?

They won't bleach that fast from light as TSA runs Metal Halide, T5s, and Radions.

 

[Duffer]

Again, what are your parameter

 

[damsels are not mean]

That acro looks like it was doomed before you even got it tbh. The fact that you have other corals thriving tells me it's probably not parameters or toxins.

Tell me what you did when you got the corals?
Was shipping long?
Did they come in cold?
Hot?
Do you drip acclimate? (Don't do this for corals)
