pinched

[JNye]

my crocea is pinched. looks just like pics I saw. My camera is not here so I can do no pics right now. I want to know if I should do the freshwater dip as per http://reefkeeping.com/issues/2006-09/jf/index.php
Its has had some stressful situations in the last couple days, lights were out for about 36 hours and then last night I installed a new sump, so because the tank was not going to be running for a few days to the sump I put some extra air in it through a powerhead venturi, I didn't realize it was blowing right overtop the clam all day today 8hrs. Obviously that stimulation right over top of him and light the deflection caused this reaction. I have school so will check back later, in about 5 hrs and try to get a pic if I can get a hold of a neighbors camera. I will report back to see if it is still pinched also. I discontinued the air also. TIA. should i do the dip!?!?

posting a pic would be best. are you running any GFO or dosing with any Fe based products? are you running carbon?

 

[JNye]

No carbon, no GFO, yet. I plan too run GFO later, is this a problem?
anyways I am happy to report my clam looks better now. I was looking seriously pinched, just like in the pic in the article i posted. Its mantle was "crunched up" and bent up wierd on either side of its closed shell. I think it was just reacting to the constant stimulation of the air bubbles.
In the future though, is the freshwater dip the best treatment we have for PMD?

Sorry, what is GFO and is running carbon good or bad?

 

[JNye]

GFO is granular ferric oxide, its a media used to remove phosphates and silicates. I don't know.
Either may irritate the clam if not properly rinsed, maybe worse, maybe not, I have only heard a few reports on this and was hoping to get a better answer to some of my questions. Its seems tough to get advice in this forum, either from limited knowlegde of clams in general or low/infrequent attendence. i guess you have to post a pic to get some answers.

Pic's would help alot

Carbon is great. It clarify's your water too

 

[skinz78]

also rock the clam from side to side to see if any air bubbles got trapped inside and formed an air pocket. kind of burp it lol

if the clam caries the PM protozoan and you start using an Fe based media, it can cause the PM to flare up. running carbon is great for the tank and can remove the Fe from the water which is a treatment for PM, not necessarily a cure, just a treatment.

a FWD is another treatment, which can rid the clam of the protozoan but is very stressful for the clam. ( at a time when he is already stressed )

there is no lack of knowledge or attendance in this forum, there are several of us that spend hours reading books, published papers and handing out advice on the topic of clams. look at it like this, if you had a pain in your chest and called your doctor for a diagnosis what would he say?? he wouldn't recommend a treatment without seeing you first. its the same here, if we told every one that posted that thought had PM to do a FWD there would be a lot of misdiagnosed and possibly dead clams.

the reason i asked for a picture was to make sure the clam actually had PM, it seems now when anything goes wrong with someones clam they jump first to PM and 95% of the time it is misdiagnosed. administering a FWD is stressful for the clam and completely useless for treating other common clam problems, it actually makes it worse.

it sounds like your clam is recovering for the ailment, so it was not PM and administering a FWD would have been the wrong course of action. it is more than likely that by injecting so much air directly over the clam you had altered the water parameters ( pH ) and it was having an adverse effect of the clam.

HTH and in the future please post a pic, it is the only way we can properly diagnose and offer a relevant treatment.

i understand the need for a pic completely, but it was impossible, and still is. gettin the camera back this weekend I hope. clam is still doing good. i just wanted everyone's opinion on FWD, from the article I posted it sounded relatively safe, especially for a healthy clam, you say its stressful but that is vague, do you consider it safe albiet stressful?

Joe I could stop by with my camera and this canister filter on my way home from work tomorrow. I'll PM you my number.

FWD is not a cure all and in most cases it stresses the already stressed clam over the edge. I think there was a thread that BarryN stated he found over 50% of maxima's don't live through FWD's
