HI all. I bought 3 sunset platys about a week and a half ago. 1 male and 2 females. They seem happy in the tank, they like to swim against the bubble current at the top of the tank. I know platys are supposed to be easy to breed, yet I am not noticing any breeding behavior. They hang out at the top a lot and at first I thought they were trying to get more oxygen, but I have 2 good airstones in there and a good breakwater from the filter. I feed bloodworms and brine shrimp frozen twice a week and flake every day. I am putting in some java moss in a few days to help for cover if fry ever do appear. The females are almost transparent in the light and I would think I would see a dark spot where the fry are growing, but still nothing. I have the temperature set at around 77 and all my levels are good. Is there anything I need to do to help stimulate their breeding or will they eventually come around?
