Blue Squamosa with pinched mantle

[Cam_official]

I just got a blue squamosa about 2 weeks ago and noticed the rear mantle of the clam is recessed into the shell. It usually has pretty good mantle extension (with exception of that rear area) in the mornings then in the afternoon, it either closes or stays partially retracted in the shell. This clam is located in my sump alongside 2 healthy adult maximas. I've been running carbon for the last few weeks with no changes in its health and I'm debating if its time for a freshwater dip. I wanted to see if you all had any suggestions for me.

This happens with one I got from a local LFS in Chicago too. I don’t know what causes it because another one that I got at the same time placed in the same tank has been healthy. I will try to move it to a lower light area

It may be PMD. Hard to tell for sure. I usually scrub clam gently with toothbrush looking for pyramid snails. Then do a 30 minute FWB. I scrub it gently one more time, if it is closed completely, before returning directly back to tank.

Both of the two squamosas I FWD died the next day, (regardless they are already half died or not). I have done FWD for two maximas, three croceas, one derasa, and one hippopus without problem. I feel they are less tolerant for FWD

My Squamosa did not have any problem with FWD. I think if it is further along in the disease process, it cannot tolerate it very well.

OK. You understand the FWD. I trust your judgement. I have read a few posts here saying the blue squamosas are difficult. I have never had one.

You may give it a shot as others have other observations, but I completely agree if a clam is too far gone FDW will just be a quicker kill.
Thee blue squamosas are difficult. Back then I had two that has been doing well and even some new growth for half a year, definitely not fast growth, but some. All that I did one day was to take them out for under 5 min to take care some bubble algae and vermetid snails, both of them perished soon after that

I FWD'ed the clam yesterday for 30mins. Today its had weaker mantle extension so we'll see if it pulls through.

How is it doing?

It's still alive... It hasn't been doing worse, but I'll be surprised if it makes a full recovery. I've started to spot feed it phyto to see if that helps it heal.

There is still hope as it has survived the FDW. Fingers crossed!

Found the clam dead today. I'll have to stick with a more reputable vendor next time.

Sorry about that. It’s really a hit or miss with them. I have got four from a LFS same batch two died in a month and two are doing great, they were in same tank also
