Mummy Fishes Can Give Birth Without Daddy Fishes

My longkang fishes really very weird, 
because the mummy fishes can give birth without daddy fishes.
Yesterday i saw a baby fish with the tail outside of one of the mummy fishes' buttock.
Then i waited around 10 minutes, really a baby fish born.
Really very weird.
My only one daddy fishes died last year december.
That's mean mummy fishes can give birth without daddy fishes.
But they can only give birth one baby if no daddy fishes's help or they will give birth 2 to 3 baby fishes.
That's also mean my last blog is approved.
Lesbian fishes can pregnant and also give birth.
