Agree, to me NLS and northfin are super foods, people can get away with medium quality like hikari and omega one as long as they keep water quality decent and give ample space.
It's funny how we treat flowerhorns and how many other hobbyist do. People who don't understand basics of ingredients or nutrition and randomly call foods high quality and low quality, suitable/unsuitable for flowerhorns like they have magic inside them.

He got comments like "Do you keep flowerhorns?", Stare meme, "most of the information is great for Cichlid care. Flowerhorns are not like other fish. I’ve kept fish for over 30 years and all the rules are thrown out when it gets to flowerhorns.", then just irrelevant replies.
