Giga Clam question

I was wondering if any one has any experience with Giga Clams and how fast they grow. I came across a beautiful 4.5" specimen on the net and was wondering how long it would take to out grow my 75g tank. If it will take several years then I would be willing to purchase it and trade it to my LFS when it out grows my tank. But if it will out grow the tank in 3-4 yrs then its not worth it. Thanks,
Larry

 

I found the answer to my question. They are the fastest growing clams and can grow up to 1/2" per month or about 6" per year! I think I'll pass. Too bad, JustPhish.com has some beautiful specimens very reasonably priced.

 

Funny, I was going to have you check with JP as he has a Gigas clam in one of his tanks and has a couple for sale on his site!!!!
They are pretty though!!! Try one of the smaller species!!!Crocea's get to 6-9 inches at tops!!!

 

I'm not so sure that they grow that fast in an aquarium but they most certainly are fast growers. I got my gigas from JP about 1.5 years ago. It's gone from a 4" animal to a 6-7" animal and I anticipate that it will be too big for my 180 gallon in another few years.

Have a look see here for a few pics of JP's "Big Boi"

I've got a small gigas and I'll have to agree they are a pretty fast grower.

Its got some amazing growth over the past 3 months I've had it.

My deresa on the other hand, damn near doubled in size, it grew way faster then my gigas has.

I use 250 watt halides for what its worth.

 

Just to chime in, the 6" is an over-estimate. Much more like =<4
