I only have one male and one unknown(in pic)I know I should have more females but I want to gradually work into getting more so I dont cause much stress...the male is about .5 times the size of the one in the picture...I had them for about a week and a half and they havent shown shown any signs of mating, nor has the Platy above shown any signs of pregnancy...An easy was to answer this question would be, "If he/she has babies....youll know" But I could wait for months...Id like to know soon...Thanks Again!RRaquariums said:When I had mine lots of times the only way to tell was size is the platy big or small compared to other females you have?
