I think there is somethings to consider here, besides the vast array of "other" livebearers... so, follow me, if you will.
Yes, everyone knows what guppies are, they are something that reminds us of childhood and the like. Yes, common and well, popular,
There is a reason, besides simply the availability - but the simple beauty, the great variety, the range of finnage and colors, shape and size. They are fun! No, I do not raise guppies, but feel there is plenty of room in the hobby, and there is certainly space on the internet, to appreciate the good things and not dwell on the negative! Warning! Guppies have puppies! LOL
