okk soo i have this mysterious little black baby fish in my tank... i got a black molly a week ago she died the next day, she did not look prego at all. i have a silver an orange mollie who had only 4 babies a week an a half ago they are all clear. i had a prego dalmation mollie who died a few days ago. i just now found this baby all black fish, cant only black mollies have all black babies?? im sooo confused i dont know where it came from. oh an the black baby is just a tad bit bigger then the babies that are a week an a half old... plzz help.. p.s its new name is mystery!!

I have a blue var platy from an orange calico, so it's entirely possible to have had a molly come home pregnant from a possible black male encounter at the store, or it's possible the dalmation dropped 1 before dying that has been hiding for a bit. This is how I got the blue platy. I had 2 orange calico females and a white male in my 10 gallon tank in my room while my 20 gallon in the living room was cycling, moved the platy to the 20 when it was ready and a week later saw a couple baby fish show up in the 10 gallon.

It is a black molly obviously. Yes, I have had a WHITE Molly give birth to pure black fry. It depends on both parents and their DNA strands.
