Absolutely beautiful! That's such a gorgeous set up and the animals within it look amazing. You're both a talented photographer and aquarist, it seems. =)
I've never seen nerites like that in the US - really a shame, because those colors are absolutely stunning. You have a great variety of shrimp as well, and it's fascinating.
Out of curiosity, which shrimp do you find the most "fun," and the best looking?
