Tridacna clam poll

[Len]

I've been wondering how long people have successfully kept their clams in captivity for. Does anyone have problems keeping Tridacnas alive for extended periods of time (1-2 years or more)?

Also curious as to who's got the oldest captive clam and what species?

I'm a sucker for clams but I have had some failures with them as well. I kept a beautiful maxima and a derasa for a little over 3 years but lost them and about a dozen others a couple years ago all at the same time.

I've been restocking and have to many clams again and the oldest is a nice maxima I've had a little over 1 year now.

I'm also curious what the longest time frame someone has kept a clam alive in captivity is as well.

Waikki Aquarium has T. Gigas. In 1982 Bruce Carlson received two T. gigas clams at the Waikiki Aquarium, one just settled and one about 5 years old. Now, they are reportedly the longest kept in captivity, and two years ago the big boy weighed 167 pounds.

You can see a pic that a buddy of mine posted on another forum. Can't find any links to pic on http://www.saltwaterfish.com/vb/showthread.php?s=&threadid=124267&highlight=gigas

T. gigas, half a year
T. crocea, 3 yrs
T. deresa, ~5 yrs. (some says mine is a gigas/deresa hybrid :?)

That T. Gigas is amazing. It was propagated in 1977 from the Micronesian Mariculture Demonstration Center in Koror, Palau.

The adult powder brown tang really shows how big these guys are.

I know it's not a Tridacnid, but I had a H.hippopus for almost 10 months until a huge salinity dip caused it enough stress to start receeding. I couldn't stop it after that...

I view tridacna clams as one of the easiest reef organisms to maintain long term. In my experience, they are down right hardy as heck. There is no reason why, if you purchase a healthy clam to begin with, it shouldn't live many years. I've only lost 2 in my reefkeeping career, and those were both very small individuals that were almost starved to death before I purchased them.


2 T. maximas, 1 is five years old.
1 T. squamosa
1 T. derasa
1 T. gigas

I've had my hands on 4 of the 5 frequently imported Tridacna species and a Hippopus. I've kept a Red Sea Squamosa for over 8 years and a Tiger Derasa for over 5. The sad part is that each time I traded them to a LFS after they've grown too big, they died within a week.

I have a T. Gigas and a T. Maxima that I have kept for 1 year and 9 months. The Gigas is still showing good shell growth, so I have no doubt he will remain healthy for years to come. I would expect him to live for a long long time, barring a catastrophic equipment failure. The maxima really hasn't grown much.

Here is a picture of my 3-4 year old tiger derasa I got from Dr. Mac.
