Thanks for that, Ken! Hi again AVN!

I've noticed that all of my Opae Ula have the dark area behind their heads. It's color a bit variable depending on what they've been eating, just like what I see in my ghost shrimp, (only its even more obvious in them). I did assume that it had nothing to do with gender/developing eggs like what I see in my Cherries.

It does seem to me that the best way to sex the shrimp in question is by claw type, and think it strange that it wasn't mentioned in your emails, Ken. Perhaps you can email them back and directly ask about the claws?

I'm guessing you've noticed the different claw types...

Thanks again guys!
