"Anyone know why it has orange eyes but isn't blue"
Good luck with your tank.
"Orange eye blue tiger" shrimp are just like Rili shrimp, a selectively intensified coloration that exists in wild populations. Orange eyes, black eyes, blue bodies, clear bodies, blue stripes, black stripes, brown stripes, red stripes, all exist (to greater or lesser intensity) in wild populations. When somebody is selling "OEBT" they're selling a line that (hopefully) has been selectively bred to create _mostly_ Orange Eye blue body tiger shrimp, but even the best lines will throw some wilder variance.
As far as everything else goes, I have the same concerns as above - There's no dates on the pictures but you seem to have thrown the tank together from parts in under a week, I hope you have put thought into the parameters of your water and the maturity of the tank, because in that small of a tank, and with shrimp, it all counts.
