Saulosi maturity info.

[Pharaoh]

Ok. Thank you for letting me know that. I thought that all the males would change their color a little bit. I did notice that one of the yellow ones had a couple of extremely light colored black bars. I guess it is possible that that fish could be a male.

In some cases, yes even the 3rd or 4th dominant males migh show a bit of black, but then sometimes no. I do not want to make you think that you have all males, I was just pointing you in the right direction as far as sexing without venting. There are always exceptions to the rules with mbuna.
