Nyles Posted January 18, 2007 Author Share Posted January 18, 2007 Without a pic hard to tell, but if its opening thats a good sign, sometimes when you move them they won't open completely for a couple days to a couple weeks. Pinched mantle is in short a sign of stress or disease/infection or possibly predatory snails. Any way you look at it its bad. A long story short my nitrate shot up to over 100 ppm last night and my Derasa has a small case of pinched mantle, so it can be related to multiple different things. Just take it slow and don't freek out, clam can be very slow adjusters, you just have to pay attention to the signs. Quote Link to comment Share on other sites More sharing options...
Nyles Posted January 21, 2007 Author Share Posted January 21, 2007 http://reefkeeping.com/issues/2006-09/jf/index.php :( I moved my clam up higher - slightly more flow, more light. Now the middle part isn't opening up all the way? I don't have a camera so I'll try to describe it: the mantel seems to come out except one "loop". The "inside" part of the clam is no longer exposed. Anyone got any ideas? Nothing has changed except I actually did a water change and my nitrates have gone down a little. The clam is still attached to the rock. On a note I said before.... what does clam poop look like? I think what I may have thought was clam poop was actually it expelling its zooxanthellae which is not good....? LOL you snuck that link in on me, great pics of pinched mantle!!! Thanks for sharing... and as for the rest, anyone owning lots of clams should invest in a good Wrasse (6-line or comparable) to keep parasites away. Thanks for the link.

cyenna Posted January 22, 2007 Share Posted January 22, 2007 ^^ I generally try to ask questions only when my own research doesn't come up with clear answers and thought this was a good link - now i know i don't have a pinched mantel. My clam decided to open up two days ago. BTW, weren't you supposed to post a pic of your clam after your snowboard trip? (whistle) Quote Link to comment Share on other sites More sharing options...
SeanF Posted January 22, 2007 Share Posted January 22, 2007 That exposure to air thing is the biggest myth about so many things in this hobby. Clams can be exposed to air it is not going to hurt them. Do you think that the collectors haul them out of the water in bags and the wholesalers aren't bagging them in the tanks that they are in. I actually had Walt Smith come out when I was down in LA and they had just gotten a huge order of clams in and I was trying to be careful around all of the new clams and corals and he came out and I asked him the procedure for getting things set aside for me and he asked what I was interested in hauled it out of the tank walked half way across the warehouse with it and put it in another tank. If you left it setting out on the counter for 30 mins or so it might not be good for it but there are a lot of places that recommend pulling out baby clams to put them in a bowl of water for feeding. I have heard the same myths about linkias, gorgonians, sponges. I even had a stupid customer come in and tell me that he wouldn't by an acro frag from me if I pulled it out of the water while bagging it. That one I couldn't resist telling the guy exactly what a moron he was. I pulled out a book that had a picture of a reef at low tide and asked him if he thought that all of those corals were going to die. Quote Link to comment Share on other sites More sharing options...

(whistle) Haven't taken the pic off camera yet, as for the air thing, I have exposed mine as well, but as I said its only when air is trapped that really does any damage, I have never had any trouble myself but I tilt it around and make sure no air is trapped.

impur Posted January 24, 2007 Share Posted January 24, 2007 Wow its hard to tell if there is something wrong to me. I guess the mantle doesn't lay over the shell like normal. I see those lil guys! Quote Link to comment Share on other sites More sharing options...

impur Posted January 24, 2007 Share Posted January 24, 2007 Me either!!! I thought it was part of the clam at first, i noticed the head but didn't make it out until you said something. Quote Link to comment Share on other sites More sharing options...
reefboy Posted January 25, 2007 Share Posted January 25, 2007 ive had my clams do this in the past due to fish nipping might check that out but there still here so i wouldnt be to worried.found out the tangs were eating algae off the shell next to that area it didnt like it lol Quote Link to comment Share on other sites More sharing options...
Nyles Posted January 25, 2007 Author Share Posted January 25, 2007 This was 100% caused by high nitrate in my case. It shot up to over 100ppm and now is down to about 20 and dropping. Had the ph drop due to a few things happening at the same time and caused some die off. Its under control with no fish or coral loss other than one I was going to give away, so no sweat.

cyenna Posted January 30, 2007 Share Posted January 30, 2007 how are you going about fixing the pinched mantel? Quote Link to comment Share on other sites More sharing options...
Kshack Posted January 30, 2007 Share Posted January 30, 2007 Quick clam question. Last night I noticed one of my clams expelling some white substance. Did this every minuete or so for about 5 minutes, then I had to leave. I did not know if it was sponning or what. Fish seened to ignore the substance. Today the clam does not loook very good. Mantel is recessed and it does not respond to touch or light change. My other three clams look just fine. Anyone know what is going on?

Nyles Posted January 30, 2007 Author Share Posted January 30, 2007 Sounds like the same thing someone else on this thread described, zooanthellae loss, did you move it up or down or change light source in any way? what kind of clam and what kind of lights? Quote Link to comment Share on other sites More sharing options...
Kshack Posted January 30, 2007 Share Posted January 30, 2007 No change since I put it in 6 weeks ago. I think it is an crocrea. I put in 4 and all others look OK. This one has never fully extended its mantel like the others, but did not look that bad. I am using Solaris lights. The color still looks good, but not fully openned and nonresponsive.

Nyles Posted January 30, 2007 Author Share Posted January 30, 2007 Possible it may be adjusting, how is the mantle color now and pior and how did it look in the store you purchased from? Quote Link to comment Share on other sites More sharing options...
Kshack Posted January 30, 2007 Share Posted January 30, 2007 The clam has been there and fine for over 6 weeks. No color chabge, but not open and the mantle is not extended any longer. Started after it expelled a white substance (sperm) several times last night. Quote Link to comment Share on other sites More sharing options...
Nyles Posted January 30, 2007 Author Share Posted January 30, 2007 I would again guess that to be zooxanthellae simply because if you get a clam trying to spawn in your tank you will be waking up to alot of dead stuff in there, I have heard horror stories. Are you running you Solaris lights on full moon cycle? Quote Link to comment Share on other sites More sharing options...
Kshack Posted January 30, 2007 Share Posted January 30, 2007 No. I started at 10% and that seemed too bright. Lowered to 5or 6% and still pretty bright. Turned down to around 4% about 4 weels ago. I just went to 2% couple days ago. My wife keeps telling me there is too much light at night, and it does seem like she is right. Quote Link to comment Share on other sites More sharing options...
mister crabs Posted January 30, 2007 Share Posted January 30, 2007 solaris lights?!?!?! can we get some pics of your setup? I have been extremely curious about these lights. Quote Link to comment Share on other sites More sharing options...
Palani Posted February 2, 2007 Share Posted February 2, 2007 Hey what do clam parasites look like? I found a pill bug looking one with a light tan "shell". Quote Link to comment Share on other sites More sharing options...
oldbrownies Posted February 2, 2007 Share Posted February 2, 2007 does it have legs, or is it more like a tan pill bug shell on a slug? sounds like something safe (i just can't remember the name), but if its one of them its just a harmless detrivore that lives in the sand Quote Link to comment Share on other sites More sharing options...
