Practically perfect in every way
I will add that the hillstream loach is a bad idea as they are actually coldwater fish and do not do well in tropical communities.
mmmm i thought that but wasn't sure about it. i know naff all about coldwater fish
i wouldn't foresee any probs with a gourami with barbs.
however i can see you going down a path which i think a lot of people go down and then regret later.
you go to the store and see all these different varieties of fish and want some of all of them, understandable, that's exactly why lots of us have several tanks. However for the general look of the tank you'll find it looks much more unified and a billion times better if you stick to just a couple of species, get all the same colour varieties and get larger groups of them. Like if you'd got 6 pearl danios.... that looks much better in the tank and the fish are happier, than getting 2 zebra, 2 pearl and 2 golden.
As such if it was me I'd look at choosing 1 colour of each species, re-homing the others and increasing your schools.
IMHO it would look a hell of a lot better.
