High level shoaling fish?
I'm currently stocking my new tank (it's all cycled so don't worry!) I'm gradually building up the numbers and currently have 9 glowlight tetra. I was going to add Black Neon tetra as my main shoaling fish (12-14 of them) but I'm wondering if there is a shoaling fish that would occupy the mid-high level of the water column? Preferably from South America.
I'm also going to be stocking otocinclus at some point.
Thanks in advance
