They are a "harem breeder" but do require a larger tank to be successful in it, otherwise the first female to breed beats the snot out of the remaining female/s unless they tank is big enough for the female on eggs to have her own turf around them..
Colour will vary in the babies, myself and a friend have fish from the same line we got pick of the first cross from the breeder and since then have selected the best to keep the lines going and have some very good colour coming out now, will try for some pics of my 2 males when I have some time..
