What type of flake food? Mbuna like Labs are mainly vegetarian, as Marty stated above, they should be fed a mainly plant based diet like Spirulina flakes or Veggie flakes. They are susceptible to "Malawi Bloat" if not fed mostly veggie based diet.
Do you have alot of rocks in the tank? Yellow labs are rock dwelling cichlids, so you should have alot of rocks in the tank for them to hide in.
