Bn Spawning

[MOW4T]

ok so my bn's have spawned again for the 2nd time. this came out of the blue as it did last time, so my last spawning went ok.. to begin with, but over the course of the last couple of months all fry have died out

as stated they have spawned again, now a couple of things i need to figure out hopefully some1 can help.

when do i remove dad? they are currently at the stage of hatched but still have yolk sac ( i think its whats its called)

and would i have a better success rate in, an over filtered 5 gallon or an underfiltered 10 gallon (fluval 2+ internal in either tank)

these are the only 2 options i have im afraid as i dont have any spare filters.

any help would b appreciated
