At what size did your Mbuna start breeding?

[Daven]

Hello! I have a 75 gallon tank with some younger mbuna. I was wondering what size your mbuna started breeding because i would have thought theyd start by now. Everyone seems happy, aside from my 2 male red zebras bickering from time to time until i find a good home for them (managed to end up with a batch of 6 males, sweeeeet....lol). Not all have females, but im hoping to get one or two species breeding to experience it for myself. Ill post my stock below. Keep in mind i still have a few fish to remove as i become sure of extra males. Plan is less than 20 in the end. Sizes are my best guess since as soon as i take the tape measure out to try and see, they all bolt into their caves lol

-1m/3f yellow labs (2-2.5")
-4 unsexed Acei (2.5-3")
-1m/1f Metraclima greshaki (2.5-3")
-2 male red zebra (1.5-2")
-1 male OB cobalt blue zebra (3.5-4")
-1 male rusty (3.5-4")
-6 unsexed Maingano (1.5-2")

Is it not until later that they breed? I know they have some growing to do for sure

I've had females as small as 1.5" with very small batches of fry but on average 2-2.5".
