So are you saying that you only want livebearers?
If so there are really only platties or swordtails left that are common in most countries.
the fish i would recommend are Kribs(pelvicachromis pulcher)
there are cave egg layers and will tend to the young so your involvment is only feeding.Or you could try zebra danio's there extremely easy to breed to the point its harder to stop them breeding than getting them to.
