is this fungus? is this a female beta?

Hello All,

I've posted recently(*) about a female beta my daughter got as a gift
from a friend last month;

just FYI, she was in a very small jar but I've got her a 3.5 galon hex
tank with a heater, some plants and no filter (but I'm doing 20% water
changes twice a week);

now I have 2 questions:

- there are white spots on her anal fin and on the edges of those long
pectoral fins; I'm afraid it is some sort of fungus; could you please
help me identify it?

- to me she looks like a male, she flares at the mirror and she blows
huge bubble nests.. is "she" really a female beta?

there are pics of her

the best one is

I still have to get her a big leaf'ed plant so she can rest near the
surface but, other than that, she looks very happy!

TIA!
