New To The Hobby, Trying To Breed Mollies :d

[jakeyman_i_am]

I have just gotten back into fresh water fish! I have always wanted to get a breeding tank running. I choose Mollies because they have been described as some serious breeders. I picked up:

20 gallon long All-Glass aquarium
Submersible, rechargable filter pump
10 inch air stone
Whisper air pump 20
A few plants
Submersible heater

After the tank had been up for a week I stocked it with 6 Mollies, 3 black and 3 white. Two weeks later they die. I have rebuilt and restocked the tank a few times now with the same results. I am here to narrow down what is happening!

I hope to contact every one of you to share my expirence, and to gain some of yours!

Have you got a testing kit for your water to make sure your stats are ok? It could be a problem with the water that's killing the fish.
Oh, and welcome to the board!

Recycle your water first. Be patient, it may take 4-6 weeks.
If you can get half old water and some filter pads from an estabilished tank, the recycling period will be much faster.

That's right. Recycle your water. Sorry.

Uncycled tanks usually don't kill mollies, since they are pretty hardy, but that could be a reason.
Did you remember to use dechlorinezer on the water?
Are you doing your water changes?
Check your PH. Mollies do very bad in acidic PH.
