Looks fine to me. Deresas from what I've seen and the one I've had for awhile doesn't lay it's mantle far over the shell.

I'm not sure if it will grow back or not but I'd imagine it would just like anything else. It might just take some time. If your growth is anything like mine, it will get big quick!

Good luck with it.
 
The clam looks fine except one or two spots where the mantel contracted (Mantel is not missing because the blue border is there, just retracted). That is what PM disease look like. It will get worst as the day goes on and better at night and in AM. There will be string of mucus come out around the pinched part.
I would not put it in your tnak with other clams or you will be in trouble. I would do fresh water dipped before you put it in your tank if you don't have a choice but it in your tank.
Lots of luck to you and your clams. I hope that this is your only clam.

It looks like it has pinched mantel disease rather than something bite it off.
Looks like i piece is off of the Mantel .
But we see if it get better or not.
It is ORA cultured Derasa .
I have three more clams in there .
 
Did it just happen or did you buy it that way?

If you don't see it folded under, then it could be healing already due to the blue rim. Good eye on that cause I didn't even notice it.

I got it that way.
Looking at the Pictures at PM disease at the reefkeeping magazine my clam don't look anything like the pictures .
It may be, i'm just comparing the pictures

Zoom,
I battle this disease, PM, way back when there were no mention of this disease anywhere. As far as I know, I was the fist one that descripe this problem back in 2002.
Here was the thread that we discussed about this disease back then. I also discussed this on reefland and Reefs.org.
Here is the link back then on Reefcentral
http://reefcentral.com/forums/showt...page=25&highlight=Pinched Mantel&pagenumber=1
Here was the thread on Reefs.org going on first about this problem.

Goodluck with your clams.

Minh , Ok i pull the clam out and did a FW dip for 30 minutes and put it in a quarantine tank is been in the tank with my other Clams for two days you think it was long enough to transfer the disease to my old clams ?
 
I don't know. I hope not. It does not seem to be that contagious. I think in 3 days, if it show no disease, I would put it back into your tank if you don't have optimal lighting for it in the quarantine tank.

First of i had read all your post before about PM :D
You see i order the clam from my LFS i did not wanted for them to put the Derasa in there tank so i got it in the bag so did not seen the clam has the PM disease till i put it in my tank.
You see this morning the other side of the Derasa's mantel was pinched so I know I had to do the treatment .
I have a FOWLR tank with a refu so I put the clam in there it has two 5100K bulbs on the top of the refuge it is no clams in that tank.
I hope my other clams don't get this disease.
Did you change your user name ?
Thanks for all the help.
 
I was using my real name:rolleyes: and do not want to do this anymore. That is all.
Good luck with your clams. It seem that the disease is contagious but it take some time and possible closeness of the clams. Either there is not much of free infective agent or the filter feeder in my tank is so numerous that these organism did not last long in the water column.

I see .
The clam was about a foot away from the other clams in my tank for two days .
The tank is 12 years old so yes it is many filter feeder on my tank also.
Is any thing new with the way we treat the PM disease or just the fresh water dip for 30 minutes .
Do you know how long it takes if my other clams to show and symptoms of the PM disease if the get it form this ORA Derasa clam?
thank you Ming.
 
As far as I have seen, there is nothing new on treating PM. I've seen several people have to repeatly do dips. Unfortunately, the majority of the times, the clam doesn't make it. I know you like the Deresa but I'd really see how about seperating it or possibly take it back to the LFS. Maybe they would let you treat it there and put it in their tank so it doesn't affect yours.

I disagree here. It is essential that you have the correct diagnosis. Manything bother clams, not all of them are PM. If it is PM, one dip is very effective unless there are clams in the system that is/are not treat. Early infection can be asymtomatic thus treating all the clams exposed is essential.
In Zoom's case, if the clam PM return, all the clam should be treat at once, or else treat and and put the newly treat clams in a new tank.

Zoom,
Since your refugium have adequate light, I would not put this derasa back into your tank for several weeks until you are sure that the other clams was not infected. If some of them come down with this disease, then treat and put them into the refugium.
A otherwise healthy clam is not excessively bother by FWD. I originallly came up with this treatment becasuse my back was against the wall concerning my clams. I remembered talking to Dick Perrin at Tropicorium, he routinely dipped his clams in FW on arrival. He told me back in 1999 that one time he forgot a tray of 1.5 inches Maxima overnight in fresh water, (late night dip and forget unltil early next morning so there several not 12 hrs) the Maxima were stressed but all survided the ordeal. I told Barry N. at Clamsdirect this conversation back in 2002. I think Barry communicated to James F. They both confirmed with Dick Perrin. You can read this comment by James F. about this conversation in his new article on Reefkeeping this month.
 
I might be wrong but many of the threads I have seen on here, the majority did not survive the pinched mantle. Yes it has proven to be an effective treatment but it doesn't always get it. Like Orionn stated, you might have to treat all the clams. Perhaps that is the link why most people have issues. I know a few people who have gotten PM and they were unable to save them doing FW dips.
 
Ok here is the update:
The clam was put in a different tanks refuge after this morning FW dip it is no clams in that tank.
I have the reef in close check to see any PM problems with the three other clams if i saw any pinching i will treat then in a fresh water ASAP.
Ok i dip the clam in FW thin morning about 730am now is 6pm the clam still have a little pinch at the same place but defiantly is better then was.
You think i should do another dip soon or wait the Derasa clam have the PM disease i'm 100% sure now, if was any thing else it will not get better after the FW treatment.
The clam is open 3/4 away, But not all the way yet.
Good thing i got all the other clam in small rocks so i can do FW dip easy.
Thank you for all the information.
New pictures coming soon.
Here is the picture of the clam tonight you can see some slime where the pinch was.
Sorry i had to take a better picture here is a new one.

Just wait now and see if any other clams start to develope pinched mantel. If you dipped the Derasa for 30 min, I am sure it will be cure.

Minh,
You see the picture of the little clam the mantel is still pinched some, you think it will go away slowly? or i need to do one more dip.
And how long you think will take to see the other clams start to develop pinched mantel, if they ever do.
