Anything with the first ingredient as fish meal or fish derivitives, your fish can do much better. I only learned about this very recently. Often, there doesn't even seem to be a price difference between the "standard" food and the "better" food.This food seems to be recommended a lot on websites, would you agree or would you recommend something else?
Your fish will have tiny mouths, you could try to find micro granules like the one on my thread I just linked, or with other granules, I soak them in water to soften them if they are a bit difficult for the fish to grapple with.
I think you have some issues with delivery in your area though.
