Wow! That looks very nice, especially with the wood protruding out of the water(even though you can't see it in the end).
Keep in mind that your BTOE/OEBT and CRS/CBS will cross. Meaning that they'll interbreed and I'm not so sure that the offspring are attractive. I'd say choose one between OEBT and BTOE since they're so similar and they'll also interbreed.
I would also suggest to chose a neocardina sp. of shrimp as all 4 of your shrimp are cardina sp.
Thanks for your advice, I good a lot of shrimps from Speedie "Nick" And KANGSHIANG, so I think I'll keep CRS and CBS on this tank and keep the rest on the Edge in my room.
