New clam not happy

[blufin]

So I added a clam to my tank yesterday and he looked fine. The mantle was full and the siphon and mouth were visible. Today it looks like it's hot happy. It is more closed up than I would like a new clam to be. Water paramaters are very good:Alk 10, Ca 420, temp 78, ph 8.1, no nitrates/nitrites
Should I be worried yet?

What fish/inverts do you have?

 

[skinz78]

How did you acclimate it? What kind of flow do you have around it? What fish and inverts do you have? How old is your tank?

 

[blufin]

Tank has been up around 6 months. I have a diamond goby, male pink square anthias, 2 female pink square anthias, clown tang. For cleanup crew I have blue legs, red legs. The flow is what I would consider low due to only using the return for current. It's a Mag 9.5 on a 90g tank. The clam went in the same day as the anthias and clown tang

 

[blufin]

forgot to mention a drip acclimation over about 45min. to an hours.

I don't see anything that could be an issue.. What lighting do you have?

 

[blufin]

about 120w of led's.

 

[skinz78]

Is it a Tahitian Maxima? I've never ever had any luck with them.

 

[blufin]

I honestly don't know.

 

[skinz78]

How big is it?

 

[blufin]

It's about 5-6 inches

 

[skinz78]

Yep, it's a Tahitian.

 

[blufin]

Great!

How much time do I have?

It might just need time to adjust. If your parameters are stable and no livestock is nipping at it, the only thing you can do is give it time. It also might need to adjust to your lighting.

Gotcha. I'll do what I can and keep my fingers crossed.
Thanks for everybody's input.
