I saw this on Craigslist.com this morning. Emphasis mine:
Sunburst Platy fish free to good homes
I have a whole bunch of Sunburst Platys that keep multiplying in my tank. They are beautiful fish, but it is time for them to go to another home.
There are about 30 of them that can be split up to different homes.
I have a lot to give away, but you must know that they are live-bearers. This means they give birth by spitting the “fry” out of their mouth.
They are gorgeous fish and get along with other community-type fish really well. They are compatible with Beta Fish as well [ . . . .]
The things they didn’t teach you in Biology class!
