Sajica.

I might grow out a sev with them and move it once it's larger.
LFS near by me has 2-3'' sevs for REALLY cheap. But I'll probably just get a nice FM to go with them.

It'll be a while until I get the Sajica, but I'll post pics when I do.

i pair would be fine in that tank...

if it were my tank i would do the sajica pair with 3-5 larger tetra.
