betta fish help needed

[TNG]

So should I just leave everything as it is for now do you think, dad is in a new tank trying to settle and fry are in dads old tank there has only been like five fry from day one and they have been free swimming for six days now

I'd say yes, leave everything as it is now.
Why were there only 5 fry from day one? There should be 100 fry or more. Anything in the tank ate the eggs?
And where is mother betta?

Okay thank you dad doesn't seam to be as stressed I think he is slowly getting used to his new tank. There where lots of eggs but I woke up on day 2 and dad most off eat most off them out of the nest so when they hatched and started swimming I took dad out incase he ate them as well. And mam is in a communal tank now
