I'm Worried about the clam pictured above. His mantle was full for the last few weeks after a big tank move. Over the last several days one side is not coming out of the shell.

Any diagnoses? Recommendations?

Is it possible that anything near it may be stinging it?

My own observation is that when they start going south, they open wider and wider as the tissue weakens.

Tagging along....

Try pmd(pinched mantle disease)
Mine looked similar, did a fresh water dip, temp adjusted 20 minutes (please research first) clam is great now.
Good luck keep us posted.

Check for pyramid snails, other corals stinging it, ect. I don't see any new white she'll growth so it could have been on the decline for a bit. Depending how far gone it is it may not survive a freshwater dip.

I've not seen any pyramid snails. Stinging not likely from nearby corals, no stinging strands noticed. There is a vermitid snail close by but his webs usually go away from the snail. It does look like PMD. He lost a chunk of footing (hairs mostly) a week or two ago. After reading the PMD thread... I am running GFO and Carbon (both changed last week) And looks like GFO may not be ideal. Any one else have an issue with GFO harming clams.

Gonna try an Rodi bath tonight before he gets too bad.

Good point, but I do see a decent growth ring that is not as apparent in the pic. She's starting a new layer of ridges/ scalloped edges I think.

Update... did the Rodi bath, temp and ph adjusted. I was positively sure I killed it initially.

Next morning, she had some reflexes

Not as bad.....

Right now... still looks rough but reflexes are good.

Good luck with that one. I've always had great luck with the fresh water dip on clams that come in a bit funky. Brings them back within a day or two almost every time.

In your case for the long term clam health I'd recommend taking it off the sand and placing it on a rock or on a clam cradle/tile that you can place on top of the sand. Your clam will need very high PAR for continued health as well as somewhere to anchor its foot. They prefer to cement themselves in unlike derasas or squamosas which tend to do fine on the sand. Any idea on PAR readings where you've got it now.

Ya, I had her on a flattish rock and got disconnected somehow. Tried moving up some on the rocks but she kept moving around and falling so I have her on the sand until she's healed up a bit. Looking a little better, but not 100%.

Not sure about "PAR" reading for now. China box led's ~60% whites during the peak. Keeping low to let a couple partially bleached corals (favia's and a large chalice) color up. Tank parameters are clean. I think the tank move just caused a little too much stress.

Did you check your water params? I think they like higher magnesium levels, and they like a bit of nitrate from what I understand. Mine started to do that opened a little bit, close a little bit, etc and then it was over. How old is your tank by the way?

Tank has been established for about two years, and recently had a big move when I purchased it. (I'm new to the hobby). Mag has been a little low 1260 -1290 and I have been bringing that up slowly.

Nicely done! Judging by the pics it looks like the freshwater bath did the trick to bring her around from whatever was ailing. Now that she's on the mend I do strongly recommend working to get her mounted higher up in the tank. No way to know for sure how much PAR you have on the sand, but I'm nearly positive it won't be close to enough to grow this clam long term. Higher up in the tank is your best bet. Hopefully you'll have 300+ PAR somewhere up on the rocks to give you a fighting chance at growing the clam out long term.

Glad the dip worked. At this point I would not move the clam up right away, let it recover from the stress of the dip. I don't think par was the issue to begin with. Go slow and watch the clam closely for a few weeks.
