The spot on my derasa doesn't look a lot like the pics I have seen.....BUT

 

from what I have read it says to FW dip the clam ....it also says for 30 minutes

 

a couple of people only did it for 15 cause they were scared to do it for 30    LOL

 

I have no clue what to do....OHHHH....I'm gonna pm BTLD...she use to raise and breed clams

sorry it took me so long to get back to you. my phone is dead at the moment, i need a new battery and my computer has a virus so i'm stuck on the laptop that has no caps lock or shift key working, yay me ... sorry for no question marks, shift key doesn't work, so i don't have the ability to type one. this is what happens when you leave the laptop open next to the tank while doing a water change

 

anyways, that does look lik a very mild case of pinched mantle disease, but i have one question before i'm convinced that it is pmd... does anything aggrivate it, such as a fish. i know you recently got a new lemonpeel, but i seem to recall that they are not in the same tank.

 

i would do a 10min fresh water dip.

i never have done a full 30min dip, because i am also scared. i have done 15-20min dips, but usually kept a low salinity rather than a zero reading. you could try dipping in a hypo solution of 1.009 or so to start with, sometimes this helps in milder cases. derasa clams, especially larger ones,  are fairly resilient so you should be ok.  this does not look like that serious of a case. i think two or three dips [max] every other day should fix the problem [keeping my fingers crossed for you]. do you feed this clam every or do you leave it as a filter feeder only ... they tend to get pmd more so when they are manually fed, at least that has been my experience, but most of my experience has been with maximas that are more prone to this syndrome to begin with.

 

if you can, do a bigger water change on your tank as well and change out your carbon.

 

one of my maxima's has pmd right now and i'm on dip number 4, it's getting better, but it isn't great. this clam had it really bad and i thought i was going to loose it. your derasa should be okay with one or two dips, but increased water changes and new carbon does seem to help as well.

I just did a water change Saturday, also changed filters....BUT I will do another w/c this weekend, and change one filter if you think I should

 

As far as I can tell, nothing goes near it except....this...LOL, BUT they have been doing this seems like forever...

You are correct....the Lemonpeel IS in the 54G....the Derasa is in my 29G

 

So do a 15 minute FW dip today.....then Sunday....Then Tuesday?????

 

OH...and thank you sooooo much.....

Tell the Derasa to eat it

It is fine as long as it does not irritate the clam (it may be though). You pays your money and you takes your chances.

LOL...I just figured if the Derasa didn't like it, it would close

 

Right now I am heating som RO water to match the water temp of the 29G...then I will also check PH

 

Anything else????

Well it is in the FW.....5 minutes down////5 minutes to go....I think it is P.O.'D   LOL

 

3 itty bitty asterinas, and one teeny brittle star fell off.....oh well

 

It looks good as far as shape though....when closed all the way, it fits together perfectly......I have heard that sometimes they shift and that is very bad

 that looks fairly normal after a fresh water dip.

 

i agree with spanko, the clown goby is enough to cause it harm.

It's in a crappy position, and I really don;t know if I should reposition it or not...

 

but here are the pics.....

The pic makes it look like the mantle is away from teh clam on the front, but it is just how it positioned itself by the glass.....You can still see the one area top left, and now there seems to be an area bottom right...WHAT should I do now?    same...another FW dip tomorrow????

leave it be for today and see how it reacts. you might want to wait til monday night or even tuesday to do another dip if you're concerned. you can also try a hypo dip instead of full pure ro water.
