Do these look healthy?
http://s31.photobucket.com/albums/c373/euchre_skillz/drs yuma/



I got them a week ago, how long before they adjust? What are some sure signs of stress or death in yuma?

Im was told they look normal and that i should not worry, for some reason i dont think they are healthy or normal, they looked much much much better upon arrivial and the following few days.

What would you suggest i do with these yuma if anything?

Tank has a 150w 14k bulb a foot and a half off the tank and it is a 20g high with about 35 gals total system volume. For flow i use 1 hydor korrila pump #1 and two maxi jet 900 with hydor wavemakers on them.
 
please take a look at the photos from today

I created a new subfolder with the date.

I am without a doubt that they are dying, they appear to be shriveling up and comming off the rock and spewing out junk from their gaped open mouths all day long the last few days.

I contacted the seller and they told me it was normal, I dont think a coral dying is normal.

Give it to me straight, If you think they are going to die let me know, if you think im insane and need to calm down tell me.

They are in shade and low flow already i picked the spot for them before the seller ever had them packed up and shipped. I knew their (yuma) requirements and i belive i have met them.
 
you have a ton of flow in that tank, it is only 20 gallons after all, at least for a yuma...my yumas react badly to any kind of strong flow, you may need to point pumps away from them or something... also you have a lot of light on there too, yumas need a lot less light and flow than floridas and you have aver 7 watts per gallon of MH
 
The light is way off the tank and they are in the deadest flow and lowest light in the tank. They are actually shaded from a maxi jet right above them. They dont sway around or anything from flow, you have to realize that tank is stacked to the surface with live rock, i am doing everything i can to keep water moving with the pumps i have.

I have other yuma in there that are doing just fine that get more light and flow than these guys. I do not feel that is the problem and belive me i have considered it. The other yuma is new too so i dont belive them being new additions causes this either.
 
I'm going to give it to you straight. The ones on the rock look bad. IMO, you will be lucky if any of them make it. Wild collected yumas are "hit or miss". Also, different yumas do require different lighting, experimentation is the key. I have some orange yumas that like almost as much light as my floridas. I also have the same type of yumas that you have in the corner of your tank, those look healthy. It is a good idea to start yumas off with lower light and I always keep them in low flow. HTH

Ummm...they look fine to me.

I'm not sure what you guys are looking at, I've seen plenty of Yuma just melt away...you will know, it just melts and you won't find a trace of it within hours. Those don't look like they are melting.

And when Yuma's are stressed, they will detach from the rock.
 
Ill update the album here in a few mins Jimbo, i think you might change your mind seeing them today.

ntfish, i could not agree more.
 
Yumas do not always detach from a rock when stressed or unhappy. I have seen them either melt away, or just slowly get smaller and smaller over time while staying in the same spot. If the light has been on for at least two or three hours and they appear flaccid and are gaping, it's a bad sign and they are most likely not healthy. There is no way I would buy a colony if they looked like what is on that rock.
 
Those look like mine did just before they all died. They were healthy for 2 1/2 months and then one day all of a sudden just started to melt away. I've only got two healthy ones left now a month later...
 
Are they melting or just sitting there all shrivel up? The "lifting" of the yuma does seem like it is under stress. It does look like it is a little bit stressed, but that happens when they are shipped. Let it settle in the tank for a week, and keep it under low light and low flow. It is a bit late, but always take your time when acclimating the corals. Ricordias are usually pretty tough, unless you see melting...once you see it, you can kiss it goodbye.
 
It is in the tank for a week already and it is in low light and is in low flow, the rock is sitting there in the shadows, i raised my light and moved them back farther and they only got worse.

I did take my time to acclimate these corals, this is not the only coral that came in the order, its just the only ones dying.

I was just basically looking for confrimation that these guys dont look all that healthy from people who have had experience with yuma because i was told by the seller that they look normal and i sould not worry. Personally i am new to yuma but i did my reading on their care. When these guys came in man they looked great... a few days later and ive got 100 bucks worth of dying coral on my hands. This is the second shipment from the ppl and the first one was in shambles when it arrived. Now i got to go back again and spend more of my time to try and get this situation fixed.
 
Well, if they are deteriorating, then what I would do is to do a significant water change. That is what I always do when I see a coral stressing because that is usually the culprit or something has changed in the water. Then I go about looking at the lights, heaters, temps, current in the water...etc etc. That is the usual procedure I use when I have a healthy coral go bad on me.

But this is a little different, it was shipped, so you probably know what was the cause of stress. But you said it looked good, and then went bad...so I would recommend you do the same procedure. Yumas are a lot more picky than Floridas.

Go do a water change, I always find the corals like it. The one time I remember I had massive die off was when I actually switched brands of salt for the water change, and I guess the 2 mixtures caused about 80% wipeout on my tank. So stick to 1 brand of salt and keep using it. Good luck on your polyps.
 
Well i fragged worst ones off the rock and sumped the rest, we will see how it goes but they are starting to gel up it looks like and i am certain it will be a total loss of life. Thanks for all the opinions and advice.

I seen someone say on the boards that his yumas died too and that those were his first and last yuma. I think i feel the same. If i could get babies from a person whos had them going for a year or so in captive then i might change my mind. I learned my lesson about the wild yuma tho.
