diff foods promote diff colors?

  • We are currently upgrading MFK. thanks! -neo
It's the beta carotene from carrots that promote red and orange color. I don't remember spirulina promoting green. Where did you get that one information?
 
You can feed fish carrots?
 
I've never seen that result either. It does promote health however but coloration, I don't think so.
 
I know there are special discus foods that each promote blue or red coloring, but I dont remember whats in each, I know the brand is sera.
