Yes, these are fine for the Labs. Most of the difference between standard fish food and standard cichlid food is the label and piece size.LEt me double check this, just standard Tropical flakes??
In this case you need to be more careful, but it depends on species. Despite the generalization of mbuna as a single class to think about, the diet can differ quite vastly among them. A common mbuna (pseudotropheus, melanochromis) should get a considerable amount of spirulina, but it doesn't need to be more then, say, half the diet or so. Just as the Lab needs very little 'veggie' in the diet, some species, like Tropheops, should have a diet almost exclusively spirulina.i was referring to all of the fish in my Mbuna tank
Variety is the key to a healthy diet, not any specific food. My mbuna get spirulina flakes, a standard flake, a standard pellet, and the odd treat of brine shrimp, which is really not necessary, but they love it. I don't have a routine, I feed them whichever I feel like, whenever I feel like.
