Muppies

[Nano557]

I bought 2 muppies (1 male & 1 female) that ended up giving birth 2 months later, which was last night. I know that having a BiOrb 60 litre tank decreases the chance of having babies grow that grow up. I was wondering if there were any tips on having the baby grow up.
I have:
1 Guppy
2 Albino Widow Tetras
1 Gold Honey Gourami
2 Balloon Mollys
2 Muppies
3 Rainbow Praecox
and now 1 baby Muppy

Any help would be appreciated.

Do you have a picture of the adult muppies? And are you sure, they're muppies? For muppies or gollies tend to be not very fertile.

I have attached the adult muppies. I am quite sure that the baby is a muppy as it is the sane colours (black & gold) as their parents.
