The giant ones were mostly likely home raised or home bred since majority of platies in pet stores were pretty young and come froms commerical stocks. In my case, this female red wag come from someone whos decided to take down their tank. Red wag's tankmates were spotted silver dollars, fullgrown albino clawed frogs and an angelfish.. Pet stores often take in old breeders of livebearers (mainly swordtails, guppies, mosquitofish, mollies and platies).
