I have a ten gallon tank and I was wondering how many Neon Tetras and True Rummynose Tetras I could put in this tank, I was also wondering if I could have a male betta in this tank with these guys.
 
Instead of getting neon Tetra's why don't you get Cardinal Tetra's instead. They are the same size and looked just like neons except they have brighter colors and in my experience are a little hardier. I have a 29 gallon tank with a school of Cardinal Tetra's and Rummy knows Tetra's. You will love your set up trust me. As of how many to get maybe someone else can help you.
 
I'm also planning on cardinals and rummy-nose. I'm kind of curious if they would inter-school?

A good school is 6 and 6 but since your tank is smaller maybe you could get away with 5 and 5, particularly if they interschool (not sure on that). They are pretty small on the bioload so maybe you could get away with 6 and 6. I'm not an expert though so don't quote me on that.
 
I doubt rummys and cardinal/neon/glo-lite will school together as they are not the same specie. Cardinals et al are pretty much just "different versions" of the same fish.

Sometimes one or two of my rummys hang with the rasboras, but not for long. Sometimes a rasbora will swim with the rummys, but they go back to their own group pretty fast.

Rummy also grow to twice the size of the other tetras, so I wouldn't add anything else but a school of six. I have 8 in a 36" tank and they school all the time. I don't know if a 10g is big enough for them to do it at all.

Either go with the smaller neons or just the rummy nose. IMO you don't have the room to mix them.

I used to have several neon tetras and several glo-lights and they DID school together, ALL THE TIME. Now I am down to one of each and they still stay together.
 
A 10g is too small for rummynoses. They, as adults, approach 2.5" and need to be in schools of 6 or so. Simply not enough room.

Also, a 10g is too small for fish to truly school in. Fish will only consistently school of constantly threatened, or they are in large numbers in a very large space.

It's not unusual for fish like glowlights and neons to school together because they are the same size, structure, etc. Rummynose are very differently shaped and would not, as a rule, school with fish like neons.

Betta's are not good tank mates they're too aggressive. Betta's even attack female Betta's. I feel sorry for my litte rummies they sometimes get bullied by my Boseman Rainbow. The rainbow when he was tiny use to swim with their school but now he singles one out and picks on him. I'm going to be moving soon and then I'll buy a larger tank just for my larger fish and keep my rummies in their own tank.
 
we have cardinals with some other small tetra's, like head and tail lights, some gold colored ones,ect.. i like that they don't school together, it makes for some really pretty colors flowing in different directions, very pretty tank! in a 12g we have like 5 & 5 and like 3 of anouther, all small, looks great.
 
Yeah I would have to agree that they wouldn't school. I have 15 in a 20G tank and after the first day or two they stopped schooling and brekaing off on their own and doing their things. I did temporarily put a rainbow fish and a Gourami in there with them, to get them out of my cichlid tank, bu the tetras were just petrified and all grouped together hid behind some rocks vibrating in one spot not swimming at all so I had to take the rainbow and gourami out, now they are back to their independant selves.
