I have had both the clams in this tank for quite a while now, id say 2+ years at least now.
the ora gold squamosa is doing great.
came home and the tigger dersa is like this for the second day in a row, yesterday i checked for light and movement sensitivity. Still nornal.
i inspected the clam for any pest and just came up with a few
bristles atound the base.
Replaced and it started to re opening normally.

have you tried smelling for a foul odor?

 

[jdms2k87]

I haven't, i dont normally like exposing them to oxygen.

Iv lost two maxinas to pm in a seperate larger system in years past.
dont see anything decaying ect

Usually when they look like that, they're already on the way out (if not there already). sorry :(

I've moved the clam over a b, and turned it into the flow.
also turned up the flow a bit.
this is it after 20 min or so

24hrs later. This morning before i left i checked it during lights out and it was like it always is at night. Mantle extended but not fully opened.

wondering if i have a fish developing a tasye for clam...

Well, that looks better at least!

 

[jdms2k87]

Ok well after two weeks and trying out a few different locations. The dersa is still cyclin through opening up about as much as in the pictur... and occasionally shuting like in the o.p
So should ijust let it be or go ahead with a bayer or f.w. dip?

I would do a FW dip to treat for pinched mantel disease.

I would do a FW dip to treat for pinched mantel disease.

do you recommend a time period? And frequency of dips
I have read 10 to 30 minutes.
It went 12 min in temp and ph matched rodi water last night and is still showing symptom.
