Hole in underside of new yuma

[Lance M.]

I got a new yuma in last Tuesday and I've had it on the bottom of the tank. This morning when I got up I was looking at my tank and there is a small hole in the bottom of the yuma and I can see light through the other side. There are no fish the the tank and I already spent lots of time looking for hitchhikers and there are none I can find. None of the other corals are damaged.

What could have caused this? I've seen ricordea develop holes through the middle and 100% always die. Should I frag it? or what should I do?

It's on the bottom of the tank w/ 150 watt 14000K MH about 14'' from the water surface (I raised it for photo acclimation).

Everything else, acros, zoas, other yumas are doing fine.

Here's pictures

You can't really see the hole but you can see it oozing stuff out from the underside were the hole is

Here's a shot of it w/o me holding it

I've been trying to keep it clean but the ooze stuff just keeps coming out.

Also the place were I bought it has a livestock guarantee. Should I contact them about it? just in case it gets worse and dissolves.

New pics of hole coming out of top (goes through the bottom)

It started to get worse to i took it out and cut it. When I turned the polyp over there was an area on of the "skin" that was black around were the hole was.


Here's the pics of the bottom of the green yuma before I cut it-

The yuma back in my tank. It already tried to form a circle so hopefully it will make it.

Pink yuma-

I have just dipped all of the yumas in Tropic Marin Pro Cure dip and hopefully they will pull through.

That is about all you can do.....It's some kinda bacterial infection that really hits hard and fast. I have lost more yumas then I have fingers to this issue. I have dipped with a multitude of chems and have had 0% success with the dips or fragging....Hope you are one of the successful ones.

Yea I've had it happen before twice. Once to floridias and 100% of the ones that developed the infection died but the ones that didn't were fine. The second time I bought a rock with about 13 green yumas on it and they looked great for a couple days then out of no where they started dissolving. Luckily I had taken one of the yumas off about two days after I got them (before they showed signs of the infection) and cut it in half. I lost all of them except for one half of that yuma I cut. I still have that yuma, a full polyp now, about 2 years later.

The two (a green and a pink) that have the infection came from the same vendor so I'm guessing it is something from them and when the yumas had to acclimate to my light and water params, it weakened them enough for the infection to take hold.

None of my other yumas are showing signs of the infection but I dipped them just to be safe.

I'll post an update tomorrow morning but the pink one looks like a goner.

Just wondering how often can I dip with Tropic Marin? It said to repeat after two weeks but if they are still doing bad tomorrow should I re-dip them?

Not sure that is the only dip I haven't used cause I can't find it local.....It might not be something that came from the vendor but something that comes with the yumas. I have had it do that do that from multiple vendors.....I think alot of it has to do with shipping and photoacclimation.....I have one right now I just moved out of the shade after a month and half. It started stretching out for more light so I moved it about 2'' into brighter light and it is doing great. I personally think photoacclimation is the number 1 process for a healthy yuma of any color....Did you place them right out into the bright light?

They are on the very bottom of the tank w/ 150 MH 14000K 14-15'' off the surface of the water, the bulb is over a year old, and they are away from the direct spotlight effect, in the corner of the tank.

I guess when you get yumas the first thing you should do is shove them in a cave or almost complete darkness. I've been talking to the owner of my lfs and he said he's lost at least $1k in yumas from the same thing and said the same thing as you about photoacclimate. Basically put them in as little light as possible at first then slowly move them over a long period of time. So far I've lost at least $200 from previous experience and this pink yuma has got holes in it but hasn't dissolved away.

The green one looks ok. I cut the piece that I cut off (that had the infection) and it dissolved away but the bigger/healthy piece isn't stringy at all and looks like it will make it.

I've been presented with an idea from my gf. I'm going to cut the top off of the pink yuma since it definitely looks bad and hope that the "foot" will regrow. I'm going to wait 1hr (the lights come on then) and take a picture before I cut and then perform surgery.

Do you think I can get my money back? it's $140 gone......

Edit: I forgot to add I've only been running the light 6 hrs a day on a timer.

 

[Lance M.]

Well I decided not to cut the pink one. I took it out and the foot was a little stringy so I'm going to leave it alone and it will probably slowly dissolve.

The "black death" has spread to a piece of one of my yumas now and I am very, very p...... annoyed right now.

I'm going to call the vendor when they open in 3hrs since they are CA based and see what we can do. If they give me a refund I'll probably just use it on Acans. They seem to like me a whole lot more then yumas.....

 

[SPDU4RIA]

yeah, yumas are tough sometimes; i rec. taking them back and getting acans for sure
