Will guppies eat tropical fish food?

Cichlid food is designed for mainly carnivorous fish to eat. Guppies are omnivorous and so would be able to eat some of the cichlid food but they would be missing out on a large part of their diet. Tropical fish flakes are fairly well balanced for guppies.

Once again i recommend reading the ingredient list of the two different fish foods and comparing the different values. If the one you want to supplement is lacking in something that fish has in it's specific food then supplement it in If you read the labels you will see almost no to actually NO difference between the foods for many fish other than the picture on the label of the food. New Life Spectrum Fish food has a small but very very high quality well researched fish food product line with many many different species on each label and just a general name like community formula or Cichlid formula or small fish formula or growth formula to differentiate. I strongly recommend you research your food before making a decision on what food to feed them. A higher quality food like NLS means you feed less and though you may pay more initially you actually end up saving money in the long run on food. Not to mention the health benefits the quality of the food provides and the reduction of waste allowing for better water quality between water changes that leads to less disease outbreaks over the lifetime of the tank and less money spent on expensive meds.
