BN colony?

[RLHam3]

so i was wondering what would happen if i just dropped 1-2 regular BN males and 3-5 females into a 55 gal guppy colony? the pH is around 7.5 and the temp is around 80. The filter is a cascade canister 1000 (rated for 100gal) and i do 30% water changes every other day. Also there is a little more salt in the water than usual, but it's not brackish by any means. there's plenty of drift wood and plants in the tank for the babies to hide in/ graze on. I'd just add a cave or two per male. The guppies are fed flakes and blood worms, the plecos would be fed algae wafers, cucumbers, carrots, and peas.

Would they breed in these conditions?

Also, once the babies hatch could I just leave them in there until they were an inch or so?

If the water parameters are too off, would this basic set up work with different pH, temp, etc.?

bristlenose will breed in that with a cold wc
but you will need more males or les females
you need 4-6 caves too

i was thinking maybe a 1M-2F ratio?
so either 1-2, or 2-4?

you need 1 male per i egg clutch
so what i do is one female for two male
she will go from cave to cave laying eggs as she gos
