The guppy but won't keep livebearers anymore, always seem to come down with something, and was sick to death of they dying. they are not one of my favourite fish anymore, got over them and moved on.
Wow I'm suprised platies are at the top. I am a fan of all livebearers except endlers never kept them. It's hard to find good petshops around here so the best livebearers I can find are most of the time guppies(big suprise). I love swordies and platies tho just haven't been able to find many good ones.
(voted for mollies, my first livebearer. lots of good memories of when i was younger seeing all the babie fish)
Guppies. Used to have a few males, but gave up because of what rotten luck I have with them, because of the horrible imbreeding that goes on at my lfs's. When I feel ambitous I might try again.
