I don't buy the idea that you need lots of variety. If it is good quality and nutritious that is all you need.

I have raised a ton of African cichlids (15+ yrs), including many species of tangs, from fish classified as piscivores, to fish classified as strict herbivores, including Tropheus sp., all raised on NLS Cichlid formula. I have also never considered the ingredients, or the sources of ingredients in Dainichi to be better than NLS. Quite the opposite.
I would actually place Northfin over Dainichi in terms of overall quality. I have trialed it long term on a number of fish as well.
Dainichi still use outdated and lower quality (and cost) sources of protein, such as soybean meal. Not a bad food by any stretch, but better source of ingredients? I don't think so.
