You don't still have the shells of the gigas () do you?

[Chris L]

Ok so i found a little piece of live rock that was a perfect bowl! He is now at the top of my pillar about 6" below the surface of water. Sitting at about 300 PAR. He has spun around 180 degrees but seems happy. Not quite sure if he's attached yet but i'm guessing so. He has been in this position for 2 days now and has not tried to jump ship yet so he must like it there. My led channels are all less than 40% currently so i may bump it up slowly. I would right now but i don't want to fry my other corals.

You don't still have the shells of the gigas ( ) do you?

Sounds good to me ! I did send the shells, you will get them in a couple of days.

Damn. I'm thinking a set of valves from a large gigas to go over my tank setup.

[Chris L]

Great! Thanks for the shells! Ill use them next time.

Lighting? DIY LED: 24rb @1a 12, CW @1.5a, 4 uv @ 700ma, 4 deep red @ 700, 4 teal @ 700ma

Did you ever freshwater dip the clam? no

Calcium/Alk Method? Kalk in ATO, Calcium Chloride when levels need boosted, baking soda to raise alk
Where and when did you get it? LFS

Do you purposely feed your clam(s) and what ? oyster feast 1-2x a week

 

Revised: I actually measured and its smaller than i thought. 4-5 in not 6-7

Ive had mine about 14 months now never really measured it, i would guess when i got it it was 3 or so and maybe is 4-5 now. It has been alittle sick lately after running some phosphate removers that i didnt rinse well enough, also caused an alk crash. Its opened up a bit more and isnt gaping as much.

I'm not the expert but that looks like a crocea to me.

Metrokat is right thats a Crocea. Not only that but I hope you know that a 6 -7 " crocea is insanely rare. There are arguments that they dont even exhist. I personally have seen 6 inch croceas, so Im glad I found you to back me up man!

[Chris L]

Awesome clam!!!

Tridacna crocea is often confused with T. maxima. In this case, the more exaggerated elongation/asymmetry of the T. maxima shell is again a strong identifier. Scutes, when present on T. crocea, tend to be further spaced and smaller, as well. Also, the byssal opening of T. maxima, while being large at times, still is not as large as that of the typical T. crocea, and is more likely to be considerably smaller.

sorry scutes was the wrong work, i meant more of the 'scalopes' the shell is not smooth like most pictures of croceas i have seen. here is a more recent photo of it, it sick and i made a thread on it but you can see what i mean better.

[metrokat]

That does look like a Maxima, you are right. Let's just call it an alien.

Scute is the correct word. Crocea clams actually have scutes, but they get scraped off or 'melted' as they try and burrow into the rock.

 

I wish you had a picture of the byssal opening, it would pretty much remove all doubt

Species of clam? T. Maxima

Lighting - bulb, ballast and count? Steve's LED retrofit kit for JBJ 12 Nanocube
Clam depth in the tank in inches? currently 12 inches, will move higher once it attaches to his rock
DOC level estimate?not sure
Do you skim?no
Do you run carbon?chemipure elite
Do you run GFO?purigen
Did you ever freshwater dip the clam?yes (has small amount of bubble algae that I took off and wanted to clean it out
Are you seeing new growth? just bought it
Calcium/Alk Method? water changes
Where and when did you get it? yesterday, 6/20/2013, LFS (beautiful little guy, black with blue stripes, and half off!)

Do you purposely feed your clam(s) and what ?whatever i feed the tank, although since this guy is tiny I may purposely feed him oyster feast or something

 

I brought him home last night and put him in the tank once my lights were already off, but he was opening up almost immediately. I'll snag a pic tomorrow since I won't be home tonight until after the lights go out.

[TheKleinReef]

I took carbon out of my 29g. now its only phosban and purigen. i noticed a little cyano patch in the low flow section of my tank, but both clams seems to be doing really well.

slight gaping, but it wasn't about an hour and a half ago.... i'm trying to find the pattern on why it gapes occasionally. the crocea almost never gapes, but the maxima does for about a few hours a day...

[Grumblecakes]

2 new entries i got today, small and i know the risk but they were 29.95 each.

 

squamies, about 2in each. here is a pic of them acclimating. they respond well have been reacting quickly to stimuli.
