3 are guppies not sure about the others as I have no idea who had them! Lol just woke up and they were there. Any idea? I thought maybe platys because of the orange and black coloring but I really thought all my platys were boys. I have platys mollies and guppies in the tank. Also how long before they're big enough to let go on the tank? They guppies are about a month the others like 6 days I think.
