I love hippo clams! 7", nice! If I had my
larger tank setup I would snag it!!

Clams hate me right now so I'm taking a break from them.

that's definitely a hippopus. notice how the mantle only comes up to the top edge of the shell. on a gigas the mantle extends slightly over the top edge of the shell.

agree with phoenixstar89. the gigas I had also had pronounced ridges on the shell. they have there identification correct imo.
