I love killis, but they jump like mad.
I need something more silvery or bland really, but nice schooling and behavior.
I have color in the 180, but more subdued plants, in this tank, I need the opposite contrast.
I have a few Rosy Tetras, nice fish like Serpae's but deeper red. They blended in so well with the red plants.
Brass tetras are too artificial for the color scheme.
I also have those in my 70 Gal.
Rummies did well, but munched on plants as they pack hunt for food.
