skyfreak73 Posted December 20, 2009 Share Posted December 20, 2009 Howdy reefers, I recently got a nice T. maxima show piece (about two weeks ago perhaps), and I recently noticed a small area where the mantle seems pinched. I noticed it the same day that I floated a livestock bag, and it's entirely possible that the bag may have hit this part of the clam. But I also lost a T. maxima recently (my two T. crocea and one T. derasa all seem fine), so I'm being extra-cautious. I didn't give the last one a freshwater dip in time, and while it looked improved 24 hours after the FW dip, it declined rapidly about 48 hours later. I'm thinking about giving this one a FW dip. If this is Pinched Mantle Syndrome on this one, I want to nix it quick. TIA! Quote Link to comment Share on other sites More sharing options...
+mcallahan Posted December 20, 2009 Share Posted December 20, 2009 I'd leave it be. It'll heal up fine if its getting enough light and healthy. One of my clams did that once and a couple of days later it was fine Quote Link to comment Share on other sites More sharing options...

One of my clams did that once and a couple of days later it was fine Thanks. I've been on the fence about the FW dip, so you just swayed me off the fence and onto firm standing. I'll leave it to heal, but if I see it progressively worsen, I'll reconsider the FW dip. Quote Link to comment Share on other sites More sharing options...
skyfreak73 Posted December 22, 2009 Author Share Posted December 22, 2009 I think it's progressing. I don't want to make the progression worse with a FW dip...but I don't want to wait too long either. AARRG!! Quote Link to comment Share on other sites More sharing options...
Gonzobob Posted December 22, 2009 Share Posted December 22, 2009 While not a specialist I did find some suggestions online: Run carbon if you aren't already (obviously be sure to rince first) Discontinue any GFO or phosban if you are running them (different batches may contain metals that clams can react badly to) Check carefully for snails or other irritants around or under the mantle Also, what fish are in the tank. I ran across several reports of clowns and tangs causing agitation. Quote Link to comment Share on other sites More sharing options...
skyfreak73 Posted December 22, 2009 Author Share Posted December 22, 2009 Currently have .25 cup of carbon in my return flow. I don't use Phosban or GFO...using Polyp Lab System Reef-resh to control nitrates and phosphates. I haven't seen any noticeable snails or other things which may be irritating. As far as livestock, I got rid of my clam-nipper (dwarf cherub angel) 4 days ago. I saw him nipping on one of my crocea clams. I do have a Kole tang, but I haven't noticed him harassing the clam. He mostly likes to graze on the live rock. I've got 2 skunk cleaner shrimp, a flame hawkfish, a cryptic wrasse, a midas blenny, and a blue assessor. Thanks for the advice...still thinking it's an infection of some sort. /sf Quote Link to comment Share on other sites More sharing options...
cmanning Posted December 22, 2009 Share Posted December 22, 2009 My husband & I are no experts but we did loose a football size squamosa (we had for 4-5 yrs.) to pinched mantle disease....This happened after bringing in a baby squamosa (which initially was the 1st to show signs of the disease). The baby squamosa was treated accordingly to this article : Troubles w/Tridacnids. We managed to save the baby but lost the large one . Try to check and see if anything at night might be bothering it. I can understand the frustration on whether deciding on your next step, to either save it or damaged it even more. good luck. -Cindy- Quote Link to comment Share on other sites More sharing options...
fishypets Posted December 23, 2009 Share Posted December 23, 2009 Call up Bruce where you bought it and ask him. I had my eye on that clam, she's sure a beaut! Quote Link to comment Share on other sites More sharing options...
