mbuna tank problem.

I agree with Blue and Pitt; aggression and small space may be the 2 main issues in this case, with more reasons due to the presence of red zebras. Watch carefully how they interact to each other.
 
If there are always particles in the water you are possibly not cleaning the gravel enough/properly, and as suggested get some finer filtration media for a start. I would also focus on gravel vaccing during water changes.

I would also change more water - what do your nitrates usually read at and how do you test btw - I would change 50% minimum - should be a breeze in a 30.

Those would address any acute difficulties regarding environment.

Medium term that tank is not going to be big enough for a happy population...I suspect your orange labs are actually zebras...they will kick the labs butts over time..if you're keeping the fish you need to focus on a larger tank - a 40G breeder (three foot long) would be a nice upgrade, a 55G would be even better and you could have a bunch more fish in there which would also help with their sociability. They like a lot of company but your tank is not big enough to support that.
 
Thanks to all for the ideas so far. If i was to remove the red zebras what do you think i should replace them with and how many? I would like some thing blue and black if poss.

I wouldn't your Labs would be enough maybe add a couple more labs of the same size for a total of 6 that will be pushing it and remove any rouge Labs that are causing problems later down the road..
 
^ I totally agree with Pittbull.
 
I also agree, no other species, just labs.

If you were willing to remove all your fish are start over I would suggest Ps. Saulosi. They are a dwarf mbuna and would be better suited to the size tank you have. They also make a nice species display since the males are blue with black stripes and the females are bright yellow.
 
No more fish in that tank when you remove the zebras...bettter would be bigger tank and more fish, or as blue says replace with e.g. Pseudotropheus Saulosi.
