Clam ID

I love the deep blue rim with black dots on yours. This will look great next to the teal colored maxima or squami that you will buy next.

The black dots around the rim are what set this clam appart in the LFS, the others looked nothing like this guy did. He’s opened a bit more today, still not enough to see the syphons

What a great informative thread! I learned a lot!

Here he is opened although still not fully extended, I have moved him further up in the tank due to the Pistol shrimp being down in that corner and pushing sand onto the tile the clam is on. If need be, I can now get a better photo of the scutes and overall shell.

The dots around the rim is highly indicative of a maxima as well. If you just search for pictures of maxima online,you should be able to spot the signature row of spots in many maximas.

The siphon, now, it's extremely confusing as well. Some maxima can have elaborate siphons. So it's gonna be hard to tell apart from squammies.

Will a photo of the scutes help at all?
Also, I cant tell but the pattern looks more like broken stripes (Similar to my deresa but broken up and blue).

Perhaps a photo can help.

Have you look at shell symmetry?

This is a picture of a sick $quamosa by @Suesea.
This is the picture of typical scutes of a Squamosa at about 3 inches.

Here’s a photo of the scutes, as for shell symmetry it’s rather unsymmetrical as shown in the photo (It’s leaning on one side).

Mine is only about 1.5-2 inches in length which is why I say the scutes look large for its size.
That is a beautiful squamosa though!

The dark spots (eye spots) all in a roll at the edge of the mantle of this clam is typical for Maxima. Squamosa also have them but much less in number.
Your clam is growing well (wide area of white shell). Those scales are typicel of a healthy Maxima. The asymetrical of the shells, the typical scutes, the coloration and the whape of the mantels all pointed out that your clam is a Maxima.

 

[OrionN]

My clams. You can see the scales of the Crocea and Maxima, but the mantle extension of the Squamosa obscure it's scales. All the clams are at optimal extension. Lower the light will result in hyper-extension of the mantle. The central part of healthy Squamosa (mantle beween the shells) is wider in Squamosa than Crocea or Maxima. When the clam is sick or stressed then we cannot use this characteristic. You can also see the arrangement of they eye spots. Not all Maxima have prominent eyespots line, but NONE of the Crocea or Squamosa have this prominent line of eyespots.
Noae mantle color and pattern is really unique. The elongation of the Noae is extreme, much more so than a Maxima, often the length to height ratio is 2:1 or more.

I believe in the LFS we weren’t able to see the scutes unless looked at side on, however in my tank he hasn’t pushed out full mantle extension so I can’t fully agree with that.

The mantle extension depends on multitude of factors. Stress level, health, current, threat, disease, immediate environment condition...all come into play. My observation are on healthy animals with optimal condition and not threatening by any fish or mobile inverts.

He wasn’t in with any predators and was in optimal conditions. Hopefully in my SPS heavy tank he pushes the same amount of growth. I already have a thriving deresa in there so hopefully it does just as well.

Your clam looks great. He is just new in your tank, given a little time, we will be just fine. Since he is new there, he won't be stress free for a few more weeks. Shipping and change in environment stress the clam, but he will recover soon enough.

Mimosa with a white patch that’s shown up, behind siphon. Any ideas @OrionN ? After seeing this I’ve moved it over towards the center of tank under light which is a Kessil 500x. Par was 170 but I’ve moved the light up 1/2 inch more so maybe a little less. Also adjusted flow as not to blow the front of the clam, shows in this photo. It’s been at the left of light for years, less par probably 110, then the white spot showed up. I dose TM Carbo Calcium by hand. TM Bacto Balance .5ml a couple times per week with MB7 if it looks dirty. Skimmer. Reefer170 34g. Parameters checked Saturday: 7.3, 1.026, CA 450, MG 1200, P04 .12, N03 5, pH 8.2, temp 77.5-78
It’s an LPS tank with the clam.

but I don’t think that landed in one spot causing this.

 

[DHill6]

Todays photo, looks like another spot starting to the left of the intake.

 

[OrionN]

The intake is the larger of the two opening. I can't see much with the blue light. Can you either filter or take a picture with white light?

 

[DHill6]

Intake has always opened wide

 

[DHill6]

The white patch ran up the back of siphon when it first showed up last week.
