Tridacna keeps moving ?

[tbub1221]

So I finally got a clam the week my new lights were in.
It's a squamosa with typical gold and Brown mantle with a little blue in it.
It's only almost 3" in length so Iv been feeding it and it caught on quick.
I read an awful lot about keeping them and all there needs and requirements which was the inspiration behind the lighting upgrade , but never found much about it moving around like this .
I wasn't sure where I wanted it so I put it in the sand bed away from my rocks a bit so he couldn't latch on and make a forever home just yet.
For the last week iv noticed every 2-3 days its moved (small subtle shifts) it turns its body facing to the left (i assume because of flow direction) and it moves further towards the glass out of direct line of the lighting , from everything I read I assumed it would be a light hog but seems to me now its trying to get out from under it.
I haven't a clue what my par is , but could it be its to much ? Or would you say its merely adjusting itself for feeding/flow reasons.
I ask because I'm aware the flesh of tge mantle is fragile and can be burned in extreme conditions.

Typically if it's moving, it's being irritated by something. Could be the light or the amount of flow on it in that area. Did you acclimate it to your lights at all, or just put in the bottom of the tank?

Yes it was acclimated , I turned my lights down to 45-50% and bumped it up some daily back to full .
I turned the lights down to about 75% and moved it to a less turbulent area .
If it seems to be ok there ill slowly turn the lights back up .
I guess if it moves again a few times I'll know its something else.

I really need to find a par meter so I can get a fugue more on what my par output is.

Where it use to sit, was the mantle moving a lot due to flow?

 

[tbub1221]

Yes it was , I would occasionally see the back side of its lips (there solid blue I wish it had more of that blue in the rest of it)
Also the direction it kept turning and putting its intake/mouth whatever its called was the more turbulent side as if to set itself up to feed in the current , so I'd bet on the flow , Thankyou for your replys

My two maximas would always drop off the rocks too. I actually lost both of them to PM.

Derasa is doing great

1) Are you sure its a squamosa? Looks a lot like a maxima. Better top down pic of the mantle?
2)"feeding it and it's catching on"? Im not sure i understand what you mean. I understanding the "feeding" tale, but the catching on issue. It is indisputable scientific facts that clams do not need to be purposefully fed. The get all their metabolic energy necessity from photosynthesis. And 99.99999999% of the time, puprosefully feeding does not benefit the clam, or tank.
3) is it in the sand? Few, if any, clams live in the sand.
4) clams cannot get too much light. They do not photosaturate or photoinhibit, as corals do. So, its not getting too much light.
