Little update: I want 1.5" tetras (so I can have more

), which means Neons, Glowlights, Black Neons, or Flames (aka Von Rios). (let me know if you know of any others.) I think Neons are too nippy. Glowlights are peaceful, aren't they? Don't know about Black Neons or Flames, although I don't think they sell Black Neons at my lfs and I'm not buying fish anywhere else. So I guess it's between Glowlights and Flames, for now anyway. :

Any thoughts? Just so you know, the Bettas will be in a group of 4 and the tetras in a shoal of 8 (I think...), so there should be plenty of fish of both species to divert aggression...
Anyway, what do you guys and gals think?
