Nitrate
Nitrite
Ammonia
Is the tank filtered

What water conditioner and any other chemicals do you use.

Are you 100%sure you have a male and female Mollie? As when I got mine a while back I got told by the pet shop I had 4 females and 1 male but intact I have 3 females and 2 males. What are you feeding them?? My mollies love flake food but they prefer blood worm
