I was researching small fish that would be good for a 10 gallon and I saw these. I tried to read up on them, but I couldn't find much information on their care that seemed reliable. There was a lot of mixed information.

How many should I get for them to have a comfortable school?
Are they in fact a good fish for a 10g?
If so, would they be compatible with a male betta? Pygmy corries? Chili rasboras?
If yes to all of those, could they all be housed comfortably in the same 10g? Ideally, I would probably do 7 of the corries, 9 of the rasboras, and 5 of the lampeye.
