help with Identifing these clams from LFS

[LMDAVE]

curious what type these are, maxima or squamosa or other?

 

[DSC reef]

Those look like tridacna maximas from the picture, I don't see any squamosa

All of them looks to be blue maximas.

So these are rock based clams? @DSC reef I remember you helping me with clams a while back. I'm with a new tank now and have the bug to try them again some day.

 

[DSC reef]

They are rock dwellers but with enough par they can be successfully grown on a sand band. I prefer getting them on rocks though.

Those all look like Tahitian Maximas to me. If under 5-6", then they are cultured, if larger, then they are wild.

These are about 2”, I went with the clam on the far left. The black/white one. Colors are so cool with clams but something about this black white was cool. I have him on a rock ledge In lower middle of my tank. It’s front and center. Lights are dimming now so don’t have a good picture. He hasnt opened up much yet...about the same it is in the picture above.

It reminds me that dead Tahitian clam, which was called time bomb then, wiped out all clams in the tank of skinz78 years ago.

This is a FTS of my tank and you can see where I put the clam on that center platform (front and center), from last night to today he turned himself 90 degrees to the right. My wife says hes moving around. I dont know if that means hes still settling in or is unhappy. And I guess this is as far as the mantle is extended right now. I havent seen him yet. Do you think I should move him further back onto that platform before he jumps off the ledge?

 

[DSC reef]

As long as the clam is not falling I'd leave it be. They can move to find a 0lace they are comfortable with. Light intensity, flow, etc, all play roles in this.

 

[LMDAVE]

Yeah, I was figuring this is a good flow spot, I have 2 MP40s on opposite ends that meeting in the middle (anti-sync with each other) so flow comes down about at that point but not blasting.

 

[DSC reef]

That's good, too much flow is not good as it will cause the clam to stay retracted which takes more energy than staying open. Smaller tridacna can also turn to the side as a result of too much light intensity but I would not worry about that at this point. That's a nice maxima!

 

[LMDAVE]

Thanks, I cant wait to get home and see it again today. The first picture my wife sent made me wonder if it was actually blue? I had to tell her to put the blue filter clip we have for the iphone over it. This was the first picture she sent before the blue filter.

 

[DSC reef]

That's a nice blue maxima. It will probably look almost turquoise from the top down.

 

[LMDAVE]

The only thing is it is white, it just looked blue because of the camera picking up the blue light from the LED's on it.
