transplanted bubble nest/update red betta

has anyone ever tried using the bubble nest of another betta to get the one
you are breeding started. I have a betta I am breeding and he usually has a
bubble next however since trying to breed him he has refused to build one, I
put some of another's betta bubble nest in there to see if he gets the clue,
I have read of this being done but never did it before...is it likely to
work

On another note, my red betta is still not swimming....I been using the
Epsom salt and pea but in three days he has only pooped *I think* once and
it was very small and maybe could of been something else, I can not get to
the store for antibiotics..my neighbor is going out today or tomorrow so I
hope I can have her grab them for me, to see if that will work, I am not
feeding him no pea's today at all.
