It would be good if you gave them different diets every day, i give my fish aquarian tropical fish flake food once a week, as its not the best thing for them really, then i have king british mini pellets, mainly because i have my neons and ottos, and soon to have some honey gouramis in, who are all small and so i thought id get mini pellets lol. i feed these about 3 days a week.
then i treat them to some bloodworm (again king british) 2-3 times a week.
my neons, and ottos, and hopefully my future gouramis like them, and they are supose to suit every tropical fish, so it should be a good diet for your fish too
