Why is my clam....?

[HoCkEyGmC]

bronzing. its mantle was once a lush purple but now it is turning a slight brownish color. still looks nice but not top notch. do i need to be target feeding again? do i need to add supplements. i use reef crystals. i can target feed if necessary. cant really get a pic because the pic looks extremely blue for some reason.
Thanks!

What kind of clam? Where is it located in the tank? How long have you had it? What is your CA?

Oh, and you don't need to target feed it. There has been several recent studies done that dis-prove the fact that smaller clams (2" or less) need to be target fed.

2 of my crocea clams. on the substrate under 150w mh lighting. had one for a month and a half and one for a month. not too sure what my CA levles are, my test kit doesn't have CA in it sadly. no target feeding?!?! ok, don't know much about that but ill trust you.

Read about clam feeding at this link. Reef Aquarium Forum • Tridacnid Clam feeding and the truth : General Clam Forum

How far is the clam from the light fixture? This may be the reason for the color change over time.

I'm hoping that the clams are on a piece of liverock otherwise DO NOT move them.....you will tear the byssal threads and possibly kill the clam(s)

Crocea clams are 'boring' (boring not like uninteresting but they actually bore into rock) clams and should be placed on rockwork. They will secrete a substance that enables them to securely attach to the liverock in your tank.

ill read it in a sec, and they are on the substrate so about, ohhhh 18 inches or so from the lights.the lfs had one at the bottom and one at the top.

that may be the reason for the color change. Also, you'll want to keep your CA levels at 380-450 for the beasties.

No gaping or pm right?
