Since my darling hubby loves me so much, he got me a clam yesterday!!! When we were at the Fish Bowl yesterday, he told me I could pick one out, and I spazzed! I have wanted one from the minute I saw one, and the pictures really dont do it justice. Its not a big one, prolly 2 inches, because I didnt want a huge one for just a 40g. I love it!!!

That's pretty!! Is it a crocea? I can't say that outloud .. and am still trying to learn about clams :) I'd like to have one in mine but im not ready for it just yet!

Also with it being that small do you have to supplement its sun-diet with any plankton or is it pretty much good to go at that size?
 
It does look like a crocea(or blue maxima...something about the shell's form is how to tell)...they like rocky surface(as opposed to most others that like the sandbed. They like high light also, so keep it up top. If it is a blue maxima, disregard the info I just mentioned and look it up.

beautiful clam...they only grow about an inch a year(depending on feeding and a plethora of other factors), so he should be happy in that 40G for quite a while.
 
Yeah its a crocea. Thanks for the tips guys! The LFS told me to place him in the sand near a rock. He knows I have T5's, so now Im confused as to where I should place him. More tips are welcome! =D
 
I have a crocea and I keep mine about 1/2 way up (12" from the surface) directly under 250w, MH wedged between a couple rocks.

If I were you I'd get it as high as you can directly under those T5's. If my memory serves me right, croceas have the highest light requirments. That's pretty retarded if they sold you that knowing you had T5's.
 
I dont know the specific wattage of the lights, but there are 2 day lights and 2 actinics. When we bought the lights, we were told that we could keep anything under them, including SPS and clams. Ill move him up onto a rock and see how he does.
 
Even under halides, croceas should be as close to the top as possible obviously still completely submerged, Higher flow than all others and higher light requirements than all other clams. Your lights will probably support it, but it should be way up top and fed regularly. Croceas are one of the only clams that prefers rocky substrate to plant its foot in rather than sand. This is likely due to the flow and lighting required to sustain it.
 
Thank you so much for your help! I moved it up about 5 inches from the top, and he already has his foot out on a rock. I usually add phyto every 2 days. Is that enough for him?
 
Description:The T. crocea clam is one of the most attractive clams and is easily confused with T. maxima. Color can be beautiful combinations of blue, purple, yellow, green, gold or orange in various patterns. In the wild, the Crocea Clams often live together in great congregations. It is the smallest of the 'giant' clams and reaches a maximum length of 6-9".

Natural Environment:
Indo-Pacific in shallow areas near shore where they burrow themselves into the substrate and coral heads. Only the top of the shell and mantle are visible once embedded.

Hardiness:T. crocea is a hardy clam as long as water parameters and adequate lighting is provided. Adequate lighting is key to keeping these clams healthy.

Lighting: MH lighting is preferred. Since Crocea are shallow water species, Intense lighting is required. They do best with lower Kelvin lighting (6K - 10K)

Water Current: Moderate to high (but not direct) water currents suit it well.

Temperature: Does well within normal reef tank temperature ranges of 75-84°F.

Feeding: Primarily or totally photosynthetic. They may benefit from feedings of phytoplankton, but it is not necessary to feed them.

Supplements: Proper calcium levels (400-450 ppm) are important for growth as is maintaining good alkalinity levels.

Tank Positioning: Can be positioned on the substrate in the bottom of the tank in a moderate water flow area if intense lighting is provided. Otherwise if lighting is marginal, position higher up in the tank in a secure location where it is not in danger of falling ( or jumping).
 
Are you sure it is a crocea?

I got one today from there and i was thinking they were all Deresa Clams? I could be wrong but I do know the Deresa clams require less light and grow faster.

I will try to post a picture of mine on Wednesday.

Thanks, but I already read all that.
 
Here are some pictures of the one I got today. I know I have no camera skills. It is much more purple to the eye with some gold highlights. The shells look the same.

Ack, they both look the same! I found an article, so maybe it will help figure out what kind they are. Im really confused now. My hubby and I think it looks more like a maxima because of the size of his byssal opening and the scutes. The byssal opening of mine isnt near as big as the one in the picture in the article of the crocea. And the shape of mine isnt as symmetrical as the derasa in the article. So we're leaning toward maxima. The problem is that at the store, they didnt have them sorted by type, but by size. =\

Very very cool :)

When you say you moved him up and he stuck his foot out onto the rock- will he attach there so stuff like big snails wont knock him over? That's awesome
