we need to be ,realistic though, nobody who's gone out and got a fluval edge is going to want to keep just one fighter in there , with stocking you just need to introduce slowly and be careful of what your putting in there .... i still stick with my initial suggestions as with slow stocking they would be fine .
Am absolutely all for being realistic.
Afraid I cannot sit by and let the OP go ahead and do what you advise -
So you still maintain a 46 litre Fluval Edge is suitable for Neon Tetras?
http/www.seriouslyfish.com/species/paracheirodon-innesi/
That site recommends 15 gallon tank, 60 cm or 2 foot length tank
minimum, Fluval edge is 43 cm in length ( 43L x 26W x 59.4H ) and neons are fairly active and quick little fish and need room swim. Also they do best in groups of at least 8 to 10 so further evidence that's really not enough space in an Edge for these lovely tetras.
4 habrousus corydoras, lovely cories, amongst my favourites

Again, I would not put these in an Edge tank, and 4 is not enough by the way, better in groups of 6+, even though SF suggest a 50 litre tank and the Edge is JUST about do able but really, its kinda cramped especially when you consider the addition of decor, woods and plants etc etc so the base dimension footprint means its not quite big enough for these guys to thrive.
Now for the Betta Splenden, can you absolutely guarantee 100% that the Betta, Louis purchases, if she decides she would like a Betta Splenden, will not kill any other tank mates, particularly neons and guppies for example?
Yes, there are exceptions and some bettas are tolerant with tank mate and even with shrimps in some cases, but more often than not, they are best as lone fish and are perfectly happy this way as long as tank is set up suitably.
"Bettas are territorial, solitary fish, and do not get lonely. They are perfectly happy -- and actually prefer -- to live alone in their tank."
Quoted from this very well known and respected Betta breeder's article

Am afraid I not know enough about these Vietamese Cardinal Minnows to really comment on those, hopefully someone who has kept these can educate us about these lovely looking fish.
Slow stocking and carefully chosen tank mates are all well and good but for most newcomers, does not always work out that way
So, with our help, pointing these people in the general right direction helps them tremendously and helps prevents tears and upsets from happening and of course its almost inevitable this continues to happen with new keepers who do not do their research and don't ask for advice firsthand will almost certainly find issues.
And finding the right advice and who to listen to is vital too, so giving good, tried and tested advice is the best start we can give for new fish keepers
