Not fully open

[ankloss]

Hello
I do not understand why my clame not open fully sins 2 days. I check my water parameters, kh 8.4, ma1350, ca 430, temp 78.8F(26.0C), salinity is between 32.3 to 33.5, po 0.03.

Aquarium critters can be just like humans, sometimes they just have a tantrum. And some of them can take more than a couple days to get over it. Most settle back down in minutes or hours, but there are some that take several days. If your parameters are good, yeah! Have you looked close for any critters that might be bugging it? Parasites, crabs, fish...?

Maybe somebody at the #reefsquad has more experience with clams.

Couple questions for you:
What kind of light are you running, any idea of the PAR the clam is receiving?
Did you inspect for pyramid snails?
What are the other inhabitants of the tank?

@DSC reef and @OrionN seem to be very knowledgeable about all things clams, I’m sure they will chime in.

How old is your tank? Looks fairly new from the photo. Be sure to carefully check for pest such as pyramid snails.

Why your Crocea is not happy?
How long have you had him? Is he growing? Was he opened more before? Are the conditions in your tank stables? How big and what other animals are in there? Are there any pests preying on him? How much light do you have?
So far you only let us know that your Crocea is not doing well and some of the water parameters. Check for parasitic Clams is essential.

That's a nice crocea. Could just be an acclimation response to a fish or invert bothering it. Make sure there's not to much flow, check the shell well for pests.

Salinity seems a bit low but could be nothing
