Stock me! Vision 180

Must haves are-
dwarf neon rainbow praecox, at least 7
cories, regular size, panda or sterbai perhaps, at least 6
1 bristlenose plec

In my current tank I have 11 neons (wild caught, so quite small) but I'm not fixed on having them in the new tank. I don't want anything else from the current set up, (see sig) apart from the shrimp, they're all bits and bobs, you know? So I'll rehome them.
A little pop of colour would be nice.
pH 7.6, kH 11, gH off the scale, I added 100 drops to the api kit and it was still orange!
I'll be planting, but not heavily, low tech, large grained sand substrate. Using the internal filter that comes with the tank. Current hardscape pic attached.
Thanks for any suggestions

So, today was fish buying day They had tons of cories, but most were uber expensive, £7-15 each. The adolfoi were especially stunning. No pandas in, so I went with 7 albino.
7 praecox, 3 males, 4 females.
Added the plec and neons from my other tank.
So, it certainly needs some colour now! Hubby wants to choose, he's looking at guppies, platies or mollies, a few males.

Quick pic now it's all set up. I have 3 'mongrel' male guppies in there till the ones I really want are quarantined.

That's a very nice aquascape.

I agree very nice. Did you paint the back of the tank black?
