Clam mantle receeding

[sstwelder]

My clam's mantle started receeding today. I bought the clam on Sunday and it seemed to be doing fine until today. The outflow valve is still flinching if i block the light over it and I saw it excrete some stuff tonight. Any help would be appreciated.

first picture was Sunday and second was today.

what is that growing on it?

 

[sstwelder]

Not sure. I was going to ask about that in an ID thread

Can you grab a clearer pic? Looks like a toad stool kinda, but would be good to see if its irritating it whatever it is.

My light are off now but they were on the clam when i bought it.

Here is a better picture of the growing thing on the side of the clam

yup/ I do believe that its a toadstool coral. Should come off pretty easy with a finger nail.

Do you know how much light you have on the clam?

 

[sstwelder]

I don't have a PAR meter, but i have it close to the top of my tank under a marine orbit pro LED.

It was at the bottom of my tank at first. When i saw the receeding i move it up thinking it wasn't getting enough light.

Is it the version with lenses? What's the intensity?

Oh and it is a new addition, so a certain amount of settling in and odd behaviour is normal.

I'm not 100% on the lense but i think it does and it's at about 90-95%

if you look at the fixture instead of squares youll see little round lenses over the leds.

Is your shrimp harassing it?

I haven't seen my shrimps around it at all but i did notice a hermit on the side of the clam before i moved it.

It looks like it could be PMD to me. Run some new charcoal and up the amount a little. Unfortunately shrimp and hermits hang around dying clams.

The Sarcophyton/Toadstool has probably been there awhile but it may have just started to irritate the clam so you should probably remove the coral.

I know nothing about the lighting fixture.

Did you check water chemistry?

Beautiful Maxima I hope it turns around for you.

My parameter were good yesterday. 0 amonia, 0 nitrite, 5 nitrate (mixing water for water change tomorrow) 8dkh, 420 calcium, 1.025 . Just got home and it seems to still be gong down hill. I will try to look at it in a bit to see if there are any pyramid snails disturbing it.
