What can I feed my guppies if I run out of fish food

Guppies can eat human food like cucumber, carrots, spinach, cauliflower, peas, broccoli, cabbage, kale, potato (sweet and regular), zucchini, tomatoes, lettuce, bell paper, pumpkin, corn. Avoid feeding processed human food to guppies. May 31, 2021 (source)
Green foods are well worth trying, as are some fruits. Blanched lettuce and cooked peas and spinach are enjoyed by most herbivorous fish, while suckermouth catfish like plecs will also happily graze on raw courgette, cucumber and sweet potatoes, even slices of melon! (source)
Guppies can eat bread, but probably you should avoid feeding them. Bread contains many ingredients that should not be introduced in a guppy fish aquarium: corn syrup, artificial coloring and flavor, sugar, yeast, folic acid and much more. Nov 28, 2021 (source)
Start with a scoop of cooked oatmeal in the center of a small plastic container and sprinkle a little bit of brewer’s yeast on top. Add worms and wait a few days. Harvest the worms that crawl up the side of the box for feeding to the guppies. Replace the oatmeal mixture every two to three weeks. (source)
In fact, they are so similar that you can sometimes feed your guppy goldfish flakes. Guppies love variety, and if you really think about it, goldfish flakes are not that diverse or different. They will happily eat goldfish flakes. You, however, have to crush them a little bit more. (source)
Cooked vegetables (peas, cauliflower, pumpkin, carrots, etc.), boiled or steamed, are great food alternatives to fish food flakes once in a while for your omnivorous and herbivorous aquarium fish. You can even feed some fish (goldfish and koi in particular) cooked rice or oatmeal. Apr 12, 2021 (source)
Eating bread is bad for fish health because it contains too many carbs and, depending on the bread variety, too much fat for their digestive system to handle properly. Fish require a varied diet of protein and nutrients, which makes bread a bad choice when feeding your fish. Jan 1, 2022 (source)
Can fish eat biscuits? Biscuits are high in carb and sugar. Fish don’t need this much of sugars and carbs. So, don’t feed any sort of biscuit or cookie to your pet fish, save them for yourself. (source)
How long can guppies go without food in an aquarium? Healthy adult guppies can survive without being fed for up to 2 weeks. Keep in mind that feeding guppies once every two weeks shouldn’t become a regular thing. But in emergency situations, or if you’re going on vacation, your guppy fish can survive on their own.

By feeding them a quality flake food designed for tropical fish, you can enhance the colour of your guppy. But if that isn’t important to you, any quality flake food should be fine for them. Apr 2, 2022 (source)
Can Guppies Eat Betta Food? Guppies can eat betta food, however, this shouldn’t be the main part of their diet, and instead should only be given to them as a treat, just like live food. While betta food will give your guppies some nutrition, it’s made with carnivores in mind. (source)
