Easy to breed fish

[Seized]

Im soon hoping to start breeding some fish. Any ideas on what would breed easy in a 20 gallon?

Convicts or common livebearers are probably the easiest. If you want something requiring more involvement then Bristlenose plecos are probably your best bet since they're easily sexed and bred. Other possibilities are dwarf cichlids like rams and apistos or certain schooling fish like white cloud minnows and danios.

Convicts breed like crazy. I purchased two tanks used from someone and each had a convict in it. Without thinking I put them in the same tank. Within a week I had hundreds of convicts swimming around.

Fancy mollies will breed you up a storm in no time. they're literally throw & forget! Just make sure you have hard water for them.

I would stay away from convicts unless you want to basically give them away the babies. When they come to a club meeting because someone has bred them, they either sell for a $1 for a bag of 6-10 or have to just give them away. 

In a 20 gallon, you could focus on a nice strain of guppies, one of the strains of rice fish, or white clouds and, with all three of those fish you could have cherry shrimp going in there as well.
