Neon Tetra With Betta

Hi, so I am planning to start a comminity tank with 10 neons and 1 betta. however I have a problem. The web says neon tetra share the same temp requirements as betta, but on here it is said that neon tetra require mid 70s, while bettas require high 70's low 80's. Ordinarily I wouldn't have risked it and just chosen another fish, but I already have neons in their QT tank, and I bought the nessecary equipment for a new 10 gallon tank, plus the tank itself. so It would be a huge waste of money to simply return the tetra. So my question is, are neons compatible with betta's temp wise, or have I made a mistake an wasted a good chunk of money?

P.s: I am aware that everyone has there own personal preferences on how they care for their fish. However if you can link me to reliable sources as to why you have those preferences or if you have personal experience with these fish (like you've cared for neon tetra for 20 years, or are a professional breeder) I'd appreciate it, because having those facts or opinions from people with experience with neons would really help me determine what I should do.

 

Personally I think neons would do better at a lower temp than the betta.

 

How big is your tank? I have tried to do that in a 10G, but the neons kept nipping at the Betta's fins... Had to separate them

 

The tank is a 10g, but the problem isn't size, the problem is temp difference. I'm trying to figure out if neon tetra need mid 70's, or if they do best in high 70's low 80's. If need be I have a 2.5g tank I can place my betta in, and I have a filter/heater that would be small enough to work on that tank.

 

Neons do prefer cooler water. In the warmer temperatures that bettas prefer, their lifespans will be shorter.

 

So about 74F? That's the temp in their tank now, but can't tell if that's the optimum temp for them
