Guppies and platies breed REALLY easy- put them together, soon u got an overstocked aquarium. Apple snails do the same thing, African dwarf frogs do too but need special conditions. Tetras will breed if pH is lowered.
yes once it has a male or a female with it
Yes.
Buy a red parrot, buy a fish, put them in a tank...
betta fish like at least a 1 gallon tank (nothing smaller) > They can live in a community tank but with no other bettas.
They can be in a community of other tropical fish of the same size.
Mollies make great additons to a tropical fish community tank. They come in many shapes and colors and even breed semi-easily and are very entertaining to watch. Need some info on them: http://slacker1202.tripod.com/id14.html
Yes snails can live in a fish tank, and they can breed.
There is no definite answer, the tank conditions have to be just right. The fish also has to feel safe, secure.... but there is no promise they will breed.... most of the saltwater breeder fish are kept in their own tank just the pair....

I think minnows but im not sure
Female Betta fish can be fairly good community style fish and should be fine. Male Bettas would massacre the community.
You put minnows or other fish well im not sure
