I have always seen people recommending bad quality food (based on ingredient and composition), so I decided a post from reddit
www.reddit.com
It's a copy of post from Kmuda and still has some minor controversial material/errors/out dated data like use of Ethoxyquin in northfin but still holds a good value to me.
On this I got the following comment (irony)

After this all hell broke loose, I was called cheap, unethical, dishonest by people who sell/make this food. The 2 people who were angry created few posts saying "You never once mention the roll genes play in the fishes quality. You insist that Omega wil make your fish a champion and it’s cheap." which was totally ridiculous.
Another thread about carophyll red was very interesting as well

There is so much absolutely great food on the market that’s been specifically designed for Flowerhorns and other Hybridized Cichlids and is so much better for them than regular cichlid foods. Foods like Northfin is great for fish probably one of the top two or three brands out there but it’s nothing compared to foods specifically designed for these Flowerhorn. Food like Excalibur’s Diamond Dust and Intense Red, Scarlett’s Dark Rise and Endless Red, Possave, Mick Kamfa, Humpy Head, Bodega, Okiko Platinum and Crystal Red are absolutely great and so much better than standard cichlid foods. Using multiple foods as supplements like Northfins Krill Gold or Bloodworms or Shrimp can have huge benefits in the growth of the fish.

I personally think think there is no flowerhorn specific food (only ones marketed as such), because flowerhorns don't have any majorly different nutrional need than any other CA/SA cichlid, people are better off buying northfin or NLS which is a lot cheaper when bought in bulk. Both contain enough amount of Astaxanthin. Many of the foods you listed do have fillers except Excalibur. Point of my post was about not looking for a brand but rather understand ingredients and choose.

My reply was
It's a synthetic version of Astaxanthin, it has a petroleum residue that might be an issue, no long term research on it exists.
to which the owner of fish food company replied
It was created in a lab but it is organic with no known side effects as stated in a few studies about poultry when it is used regularly. No know petroleum reside https://efsa.onlinelibrary.wiley.co...8ahaLKWp3C8ij_1HS1DI39fQr-KppyyfM2MJTALJUtsCY It has also been used in salmon for decades.
My reply
not sure how much the research on Poultry would be relevant and long term effects are not accounted for in salmons as well that are raised in aquaculture. Carophyll Pink and Carophyll Red are synthetic color enhancing agents derived from petroleum by-products.How can be something created in lab be organic?
His reply
omfg, seriously!!! You bring out crap all the time on studies on topics that are not the subject of the matter!!!!!! I bring one out and you say it’s unrelated!!!
My reply
sorry, did I say unrelated? Even when you posted a research on Poultry just to say something against what I said "no long term research on it exists."? I said "not sure how much the research on Poultry would be relevant". Also do mention me in the comment so that I get a notification to reply to you.

I can assure you, the lack of tagging you was not an intentional mistake. I would have never deprived you of the shock I felt at having you dismiss everyone else’s experiences, knowledge, studies, as secondary to your own. Because it seems that you are always right, even in face of the very evidence you present..... ??? Good night, hope you sleep soundly knowing you are the almighty of all knowledge that the world contains!!!!
