You Ran Out of Goldfish Food; Will Betta Food Be Fine Till You Can Get More?

Assuming it is for one or a few days, then yes, it will be fine for the meantime, but make sure not to overfeed Betta food to your goldfish. Keep in mind that if you run out of goldfish food you can supplement with fresh veggies like unshelled peas, tiny pieces of cucumber or cooked and squished zucchini as a few options.

Why Is It Not A Good Staple Diet?

Most quality Betta fish food contains a high amount of protein, because they are carnivorous and therefore Betta food should generally be avoided as a main or significant diet for your goldfish. Betta fish require a diet high in fish or invertebrate-based protein in much more concentrated forms and with a higher percentage than is ideally recommended for your goldfish to thrive.

Goldfish require a fair amount of fibre as they are quite prone to digestive problems, especially the fancy goldfish varieties (Orandas, Fantails, Ryukin, etc.). There are so many goldfish-safe foods on the market to meet your goldfish’s requirements. You should look for a high quality pellet. Sinking pellets are preferred over floating pellets for fancy variants. If you find that your pellets float, you should pre-soak them in some aquarium water and gently squeeze them. This removes the small pocket of air inside the pellet, and allows it to sink.

Many fish die as a result of improper food and/or portion sizes, which can be easily prevented by proper education.
