I read that info somewhere...thinking on the HRS site...I'll go back and see if I can find it...

Another interesting tidbit---female guppies can retain the male's sperm (even after she's had the babies) for up to 6 wks. Don't remember where I read that at... Guppies are one of my all time fav. fish... SOOOO Friendly and purr-ty! (and easy to breed...can create your own color variations!) My 50 gal. tank use to be home to many, many guppies...unfortunately they caught something and despite the Rx...I lost them all!

I just bought 3 more...(2 males, 1 female) going to try it again...
