[am07f]

Anyone see there gigas or any clam have there gills shrink?

They have gotten super skinny.

Are any of these before pic's? They look normal to me?

You need to make more room for the gigas to grow. I have a 20" purple mantle gigas on a 5" sand bed and it has 6" inches on either side for it to grow. The tank is 36" wide. It looks cramped up...
