Fish Matching again for my girlfriends tank

[Vampure]

I did some reading on Cardinals and Black Neons. Black Neons would likely fit better in the tank so she can get more of em in there (and I may use em in mine, the look really cool) since they only grow to 1.5" or so whereas the Cardinals grow closer to 2". Thanks for that about the diff tetras. It made me look which will most likely save fish and money in the long run. Thanks from both of us.

Here's the breakdown on what she got for her tank, all of which were left in a net to see how the betta would react b4 putting them in open water; neon tetras (It attacked the one she put in open water, all three died over night, very sad), a zebra danio (The betta eyed the tank like it was gonna eat it if it ever got the chance. It was moved to a different tank), 4 guppies (which for some unknown reason other than a different personality for this betta are all doing well last time I checked as of yesterday when I was at her house), and a black something or another that won't get big supposedly... I can't remember the name of it, anyway (It bit the betta once, the betta bit it once, and now they're the best of friends). Weird tank combo but hey, so far it works. I'll tell u mine really fast as well; guppies (they never were taken out of the net, my betta was attacking the net and I gave them to my girlfriend, hence her having 4), neon tetras (3 died while still in the net, and after the third one died, Mo Mo was moved to my 5 gal tank and Mu was moved to the ten gal tank where I released the remaining 3 tetras [one died later for some unknown reason, I'm guessing one of the other neons or maybe just weak] and the remaining 2 are doing well), 6 glowlight tetras (released with Mu as well and are schooling with the neons [which I'll get more of after Christmas] and are doing well also). That's the breakdown of our bettas tankmates. Sry it got so long winded.
