Today I picked up 6 platys, 3 tiny 3 awesome variety ones and one of then has a Mickey Mouse like sign on its tail and is chasing around a female which is one of the biggest platys I think I have ever seen, is it pregnant? Also have others I think are pregnant so will add pics of them all soon. I have also got 10 pairs of pure bred endlers and I'm curious to see what the pregnant females look like as mine are huge with a big black spot on belly area, if any fish look pregnant when I get to posting pics can you estimate how long until they give birth please
