How fast does a clam grow?

[elegance coral]

You can see the white new growth under the mantal. This is after about 2 months in the tank. I use kalk for all my top off. How fast can I expect him to grow? Do they get biger in captivity. I read that this one will get about 9 inches.

looks like a crocea, so on average between 1/2" - 1" in shell length per year. once the clam reaches sexual maturity the growth will slow greatly. clams like anything else we keep in our tanks will not reach the same size potential as they would in the ocean.

HTH

Well that just sucks! I want it to get big.

get a derasa mine had grown 1 1/4" in 3 months.they can grow 3"/year or so in good conditions.

Get a squamosa. Mine has grown insane. I'm about to have to sell it if it gets any bigger.

How big will my crocea get? I have seen some larger clams but they are always a brown or goldish color. I like the bright blue of the crocea but want it to get large. Is there a blue clam that gets large?

 

[CMcNeil]

the croceas grow to around 9".the larger clams are probably derasa(max around 20") or gigas(up to 4 ft).

 

[jay24k]

As far as I have seen, croceas and maximas max out at about 6". Deresas hit 14", squamosas I can't recall but mine is a foot currently. Gigas...well they just get freaking huge.

maxima's can achieve 12" - 18" in size.

Do any of the larger clams have the blue colors like mine?

Elegance coral, its hard to tell but is your clam reaching for light?

 

[elegance coral]

No. This is a shot of it from the underside. Kinda a weird angle. I wanted to show the new growth on the shell. My friend came over yesturday that hasn't seen the clam in a while and freaked out at how much it has grown. It is in the tank with my Elegance corals. The lighting is listed below.

gigas have blue in them but they get huuuuuuuuuuuge.im looking for a small one(3-4")

I was just wondering how you got that picture because usually clams don't show their new growth unless they close up.

 

[elegance coral]

These are a few more shots of my clam so you can get an idea of where it is in the tank. Sorry the pics are bad, they are from my phone. The clam is on a rock near the front of the tank. I took the original pic with the camera pointing up from below the front glass. Did this info help? It seems to be very healthy and growing like a weed.

 

[55semireef]

Very nice color.

 

[elegance coral]

Thanks.

For some reason I thought Barry told us that maximas generally hit 6" in closed enviroments but I can always be wrong.

 

[a4twenty]

my largest maxima is currently 7 1/2" - 8" in length and still growing
the gigas behind is about 16" - 17" for perspective

 

[elegance coral]

Giga is the one I want, I think. 16 to 17 inches,WOW! Thats got to be one nice clam.
