Can't gouramies attack neon tetra? I had dwarf gourami and neon in the aquarium of my father when I was a kid, and it happened that he ate one neon tetra...
Are Laetacara curviceps less agressive then Apistogramma? Do they spawn in the same way?
It varies, but IME, gouramies tend to be more aggressive to conspecifics and ignore other fish. As always, though, YMMV and all animals will not behave the same way.
