Hello all, This baby Guppy was born on 16th Dec 2015. That makes her 6 months old now. I was trying to sex her and her 3 other brothers and sisters today and noticed how fat she was and a black dot in her belly. Could it be possible my 6 month old guppy is pregnant? If so it would be by one of her brothers! Look how fat she is: And the dark spot in her belly: Either shes just a female with the dark spot and i feed her to much or shes preggers, can anyone else tell?
