I introduced 5 Yamato shrimp to my planted 90gal tank the other day. Its been about 5 days and I've looked hard. My tank is well planted so
there are a million places they can go but still.
I'm beginning to suspect the clowns munched them straight away. I even
watched to see if they had full bellies and if they were hungry when I fed
the tank. Nothing conclusive either way.
Any thoughts folks? Are yamato's nocturnal?

No carnivores in my 15 gal tank, but at times I've thought I lost some
or all of my 4 Amano shrimp. I have had about 2 months where I thougt I
was down to one. All of a sudden, all four show up again.

I don't think Amano/Yamato's are nocturnal - I've seen them cleaning
rocks out in the open durning the middle of the day. It's just that they
(sometimes) can be nervous, retreating to heavy plant cover when they're
harrassed by other fish.
