For Moscow Blue, I have 2 ribbon male, 2 normal male and 1 ribbon female.
For RREA USA White tail I have 1 ribbon male, 1 normal male and 1 ribbon female.

Should I put all together for this strain Moscow Blue and White tail or take out the male with ribbon type as they are very aggresive to the female even to the normal male.

When I suppose take out the male from the breeding tank?
Once we see the female gravid spot become biger and black or just leave the male until the fry was born?

What is your opinion and suggestion?

Thank you.
