6 is always a good round number with cories ... at least that's usually the number I use. :thumb:
If you are going to go two differant tetra schools, I'd go vastly differant colors and shapes ... ie 12 rummynose and 12 lemon tetras ... I wouldn't do two similiar shaped but differant colored like black and red phantoms though. Of course I tend to just use one school so my ideas might be odd sounding.
Oh if you can find extra females, apistos really do do better in trios instead of pairs, being harem polyogmists and all. :wink:
