This sounds like great news guys. Could I also keep a breeding group 1M/3F of say, salousi or yellow labs (or something like that) in there as well then? If so, what would the chance of interbreeding be?
I would go with yellow labs. I had a breeding trio of red empress in with 4 Elongatus Mpanga and the dominance of the male red empress prevented the male Elongatus from colouring up fully and looked like another female.
Yellow labs. and the red empress was a more peaceful tank.
About 4" as already stated by another, by this time the male will have a fair bit of colour and a deep blue face mask. Once they start breeding it doesn't stop..........Should be fun :thumb:
I love red empress probably my favorite fish, 55g should be just enough i have seen them about a foot long
They is almost zero risk them crossbreeding with any mbuna especially with labs.
