Are you interested in keeping fry? If so, the yellow labs and zebras are too much of a cross breeding risk to house together. Mbuna are harem breeders and should be kept in groups of 4 or more with 1 male to several females so you would need more of the socolofi and the blue zebras. (not sure if you mean met. callainos or not)
well as far as i can tell my ration of m:f of red zebs is good enuf that it shouldn't get complicated, but i'm not planning on keeping the other fish. what i will probably do is sell my blue zebs, labs, + keep my red zebs and socolofi and get malawii eye biters.
I would increase the number of albino socolofi if you plan on keeping those. I have 3. One male one female and the third one I'm not sure of. I'm planning on getting a few more. Recently I bought a tiny one that was the only one in the store. I'm hoping it's female but only time will tell.
Your labs and red zebra will cross breed. Atleast there is an extremely high risk of it which means they will quiet often so never distribute the fry. Even if the fry look pure alot of the times they aren't, you can only tell by that fishes off-spring.
I take it you are talking about the cobalts when refering to blue zebra? You will need to up the numbers to atleast 4 and it is important you only have 1 male. If you have 2 you will have major aggression issues.
I would also up the number of Socolofi as it is always best to keep mbuna as singles or groups of atleast 4 with 1 male and 3-4 females.
For fry control get a few synodontis multipuctatus, they will do a better job then the compressissep
