well unless u'v got somthing special there then the lfs would be the place, if u raise the fry to about a month the lfs will take them for feeder guppys and if u raise them to adults they will either take them, buy them, or give store credit. my lfs give store credit so that how i get rid of my guppys, i userally rasi mine to adults or just let them get eaten by the parents, its to much work to raise fry for a month and know they are gunna be someones dinner anyway.
