little question about new clam i got

[nutto]

I bought this clam yesterday.It's open up good but I noticed it brown stripe on it tissue look like some skin peel off .Is it because of shipping or water or stress ? Will it heal itself or anything I should do ? and Can anyone tell me what kind of calm is this ? thank you

 

[witfull]

its a Crocea, and thats normal patterning. its a rock dweling clam and needs high lighting. move him up on the rock closer to the lights~

 

[mbbuna]

Witfull is correct. if you have very strong lighting, move the clam up slowly

I have 2x250 w 10k and 110 actinic PC in 75 gal tank is it enought light for the clam to stay in the sand?I just dont have much space on the rock

well if you must place him on a sand, place him on top of LR rubble so they can attach themselves there. they just don't like substrate.

 

[nutto]

I 'll do that. thank you.

I might be a little concerned about the large opening in its mantle. Usually in healthy clams the opening is smaller than that.
It is probably a Crocea though you cant know for sure with out checking the shell and the byssal opening (largest byssus opening compared to its shell length. The shell is smooth with hardly any vertical folds.
