Need Help Starting New Livebearers/poecilidae Tank!

[FWFishLover]

I Am Going To Start A Community Aquarium With Poecilidae/Livebearers. But I Only Plan On Buying Mollies Swordtails Platies And Fancy Guppies.
I Have A 20g Tank (Which Is Perfect Because All These Fish Require 10g Minimum) I Already Have 25 LBS Of Gravel And A Big Hollow Submarine For Hiding As Well As A Plant (Type Unknown)
And A Mediumish/Smaller Fake Rock Which They Can Also Go Inside Of.
As Far As Fish Care Goes I Already Have A Filter And Heater (Tell Me If I Need Anything Else Please).
Also What Is A Good Algae Eating Fish To Mix With These Fish? I Was Thinking 1-3 Plecos (Tell Me A Good Amount Please)
I Already Have A Male Neon Swordtail (Clyde) And Am Worried He Will Feel Very Territorial At First.
Basically I Would Like Some Info On What I Need (That I Dont Already Have)And How To Prepare.

Basically you have most of what you need.
The male neon swordtail shouldn't really feel territorial as i have found my livebearers don't seem to bother each other and never have. As for plecos i would say you should be able to have 2-3 Bristlenose plecos as they stay small enough for the tank and can be kept in groups. Also some species of swordtail you could have are hyfin lyretails. Some guppy species are very pretty like this snakeskin or mosaic guppy.

snake skin guppy.

Mosaic guppy.

And for other livebearers you can decide whatever you want i was just suggesting pretty nice ones.
