I went fir the excel because i always like to see some veggie/spiriluna in the formula. Even with my ciclids.
I personally would not feed my fish
anything that contained MSG or astaxanthin. Plus if you read the ingredients you'll see lots of low quality binding agents and corn fillers. The other comment you made about the veggies if you read the label the order of ingredients is the percentage of content and you'll see spirulina is the fifth on the list in both foods. Now to the actual veggies show me on that list where they are? Where as NLS has spinach, broccoli, red pepper, zucchini, tomato, pea, red and green cabbage, apple, apricot, mango, kiwi, papaya, peach, pear. The other issue I have with Hikari and most other fish foods is they use the leftover parts that the other industries don't use rather than the entire fish, so there is more waste which is evident from the ash content. Fish can assimilate only so much mineral content, and any excess will simply be adding unwanted pollution to the aquarium water.
I could go on and on with regards to fish nutrition but as Pablo states "the proof is in the pudding".
