Congratulations on the one at least. Colors change, so names may not apply later. I had a half black, half light yellow Molly split down the middle, which is now completely light yellow. The name bird poo doesn't apply anymore.
You got any hiding places? I didn't even know any of my fish were pregnant til I found fry!! I still don't know who 'mum' is or how old the fry are. I know for certainty there's more in the tank but I can't find them.
