I would be very cautious about comparing our tansk with a controlled scientific tank. We add things and do things to our tanks that they do not. Just make sure you're comparing apples with apples.

Thanks I'm just finishing reading that article. If I did the math right the two test tanks are about 265 gallons and the gigas weighs in at about 80lbs. Thats alot of clam!
A 14" gigas does not weigh near that much. Closer to 5 lbs would be my guess. I wonder just how big of gigas was used for the study.

Thanks
Don

Looking at the numbers in the article, I would guess more like 20 lbs.

The largest calm ended up a little over 94 lbs. Wow
