Normal Clam Behavior

[Cool Cat]

Hey guys and gals, I’ve been in the hobby for nearly 20 years and just brought home my first clam. It is a blue maxima, just wondering what I should be looking for to see if it is happy and healthy. I have it in a 60 cube under a Kessil 360 in the sand bed. I noticed that it closed up as the Kessil was ramping down. Is that typical? Any advice would be welcomed!

Yeah, normal. No more light for them to utilize, so it won't have as much extension.

Prolly just getting used to things. I just placed mine in the bed and it moved around til happy . Got my first one about 4 months ago. Enjoy.

Its common for a clam to close during ramping down. Stimulus from shadows/light are healthy an normal.

Thanks guys ...still closed ...hoping that its just normal behavior for a new clam. Opens a little then closes when my blenny swims by and nips at its shell.

That's something the clam will get used too. After some time a fish swimming over it won't bother the clam anymore. It's actually good sign that it has a response.

Thanks DSC... my dkh is around 8.5 and calc is 440, do I need to bump it up? Do I need to tweet my lighting schedule to increase my max intensity photo period or will the clam adjust? Right now my lighting schedule is as follows:
0 color 25 intensity - 2hr ramp to
15 color 30 intensity - 3hr ramp to
25 color 50 intensity - 3hr ramp to
50 color 75 intensity - 2hr ramp down to
25 color 50 intensity- 2hr ramp down to
0

I would keep the tank exactly as is. As the clam keeps improving and growing then increasing photo period could be beneficial. I dont have much experience with led lighting as we've only used halide/T5 on our systems. Our new build will have all kessil so I'm excited to see what they can do.

Thanks again! These guys are so cool and I’ve wanted one for several years. Just don’t want to kill it in the first week

Your very welcome. They are my favorite reef animal, I'm fascinated by them. They can be difficult to keep but don't get discouraged. Looking forward to some updates growth pics.

Ugh, still not opening very much...when should I get worried? I read maximas like a rocky base so I placed it on a rocky plate and buried the plate in the sand. Trying the have patience

 

[DSC reef]

Can you post some pics.

 

[Cool Cat]

The first is about an hour after I acclimated him and put him in on Saturday. The second is just about t minutes ago (Wednesday)

It’s hard to get a clear pic with the shimmer of the Kessil

Have checked the clam for pyramid snails? I'd look at the clam at night on the bottom near the foot. Is there a lot of flow on the clam?

 

[Cool Cat]

I haven’t seen any snails around the mantle or on his shell, but I haven’t checked the foot. As for the flow I’d say it’s a moderate amount, he’s nearest the wall that my gyre is attached to. My wall hammer used to be in that spot and it wasn’t blown away. Do I need to move him? I tried to place him in a spot with good flow and not as much intense lighting to help him acclimate to lights.

That doesn't look good. Do you know if it was a wild clam?
Def check for snails.
