Yuma Corals Dying...

[Beausoleiljacob]

Hi Reef 2 Reef,
I have no idea why but my Yumas are dying. They were both fine until I was trying to treat some algae with Dino X. All my other corals are fine but both Yumas have taken a hit. Is there anything I can do for them or are they gonners? Should I reduce my lighting or something. They were so pretty! One has fully closed and the other is open but looks nothing like it use to and its mouth is wide open. Here are the now and before pictures.

Thanks!

Sorry for the bad pics.

I have no idea what Dino X is but usually any product that kills algae will hurt corals....

Chemiclean kills cyano which isn't an algae but a bacteria and is safe for corals

Are they dead?? [emoji24]

I don't know about the one that closed up but I lost one. It's mouth was wide open too and then it melted. Sorry. It was a Yuma as well. I read a lot of posts where people have problems keeping Yuma. Even coral dealers like tidal gardens say they can't keep the Yuma's. But the Florida seems to be no problem.

I just don't understand how they were doing so great.. But then took a turn for the worst. Lack of light wouldn't cause any of the problems right?

Couldn't say for sure. I have a Yuma in my tank right now and it's doing fine. I keep it out of direct light, seems to not mind either way. Problem I'm discovering with this hobby is no two tanks act the same. So it's hard to say why something does well in one tank but another with the same parameters can't keep one alive. Did the Dino x say safe for corals. Evan if it does it still might affect some species. Sorry your having troubles.

It's really strange.... The only corals that seem to have been affected were the Yumas. Every other coral has been fine. I wouldn't of been mad if I didn't become so attached to them. They were my favorites and to watch them just die is really upsetting. Would you recommend moving the one that is still open and appears to be bleaching. Well actually I think that is the main problem. Because it is turning neon green and expelling zooxanthellae. However, aren't Ricordeas and Yumas similar in terms of lighting and flow. Or do Yumas prefer really low flow and moderate light.

Here is another picture.

Ricordia Florida doesn't have the amazing colors that ricordia Yuma have and other than color they can be hard to tell apart. Some people have kept Yuma for a year and then bam! It dies mysteriously. I keep mine in low to moderate flow. If I lose this one I will get another ric because I love them too but it would definitely be a ricordia Florida. You may not lose them and how that's the case.

I'm new to this and am no way an authority on anything but if you search ricordia on this forum you'll more than likely find some very helpful threads from people who are experts.

Also.. My Fungia Plate seemed to be losing color, so I decided to move it out of the light a little. However do you think it is too close to my chalcie?

 

[Lonny]

I read fungia have a strong sting but do not have sweeper tentacles so your fine imo.

 

[DeniseAndy]

Your plate will want light unless your lights are too intense. Plates will need low flow and food to eat. Same with yumas. Yumas are less tolerant to changes then florida species. I hope for the best, but one certainly looks to be gone.

Careful of the chalice stingers. They can be quite long on some species.

Sounds like they are starving. Do you feed them?

I have certainly tried feeding them oyster feast. How often should they be fed?
