Live-bearer Tank

[Zafirah]

I would really like to set up a live-bearer tank in my 80L/20gal.
The plans are

3Mollies(1m/2f) (6" at 2" each)
4Guppies(2m/2f) (8" at 2" each)
3Platies(1m/2f) (6" at 2" each)
3S.Tails(1m/2f) (9" at 3" each)
4Corydorias (8" at 2" each)
so thats...............37" when all full grown

I realize that is a little bit overstocked, but, i am overfiltered and i do 20% waterchanged every 2 days.

Way overstocked. I am not speaking based on things I've read only. I am looking at my tank, in which I have Mollies, Platies, and Panda Corydoras.

Swordtails and Mollies get to 4" in length, sometimes longer, but 4" is a good estimate on the lengths full grown.

I would put Platies at 3" in length.

Some of the Corydoras stay at 2", but most get to abotu 3" in length. Plus Corydoras are schooling fish and want a group of five minimum normally.

You need to decide what you want in this tank, because what you currently have planned will most likely be a disaster.
