So then the cichlid formula is nothing different?
The "thera" content is slightly different from the standard. From size to size across the standard NLS offering, the nutritional percentages do vary. I however do pick what size I feed based on the size alone without concern about the slight variations in percentages.
IIRC the "large fish" formula is the 2mm pellet. I feed that to my malawian cichlids around ~5" and over. 2"-5" I use the cichlid formula. Under 2" I use the growth formula. However, for all I also use a large spirulina flake 1/2 of the time as well (when most of the large flakes are gone from a container, I swap the remaining small contents to a smaller container that I use for the smaller fish and refill the large container from a bulk quantity I keep in the freezer.
