mixture of guppies, endlers & platies

[mdm]

hi all, i've recently decided to rescape my old tank (2-ft)

this time instead of tetras, i'm keeping a mixture of guppies, endlers and platies (about 10 each, mixture of males and females)

some noob questions:

1. can they live together peacefully? i read that they can, but i sometimes see my endlers chasing the guppies (even though the guppies are larger in size)

2. will they reproduce non-stop? i have a fairly dense planted tank, have spotted a few fries already... i hope they won't end up eaten by the adults

thanks
