Can guppies eat goldfish flakes? Yes, guppies can eat goldfish flakes, but they lack certain vital nutrients that guppies need in their diet.

Can Guppies Eat Goldfish Food
Guppies can eat goldfish flakes, and they won’t cause any harm, but a guppy won’t thrive on goldfish food alone. Goldfish food contains less protein than regular tropical flakes since goldfish primarily consume plants and algae in their native environment.
Tropical flakes, on the other hand, serve as an excellent source of protein that guppies need to fuel their growth and development.
Female guppies also need more protein than males especially if you plan on successfully breeding them. Female guppies are livebearers which means they gestate their fry instead of laying eggs, and for this reason, they need more protein especially when they are pregnant. In addition, female guppies might not even breed at all if they aren’t eating a healthy well-rounded diet.
If you only have goldfish flakes for whatever reason then it’s fine to feed them to your guppies, but only for a limited time. Also, you want to make sure you crush the goldfish flakes up into small enough pieces so they are easy for your guppy to swallow.
Just remember that tropical flakes (Buy Online) are always the best option when it comes to feeding your guppies, and if you want to know what we feed our guppies you can scroll down to the Best Guppy Food section further down in this article.
What Do Guppies Eat in the Wild

Guppies are a tropical fish that are indigenous to North and South America. They can be found in the warm temperate waters in Brazil, Venezuela, Barbados, Virgin Islands, and Trinidad and Tobago.
What Do Guppies Eat? In their natural habitat guppies have access to a wide range of foods like plants, insects, and small microorganisms. Guppies are primarily an omnivorous fish that need to eat a wide variety of plant-based and live foods to thrive and reach their full potential.
Live Food
Guppies will eat small organisms like insect larvae, small crustaceans, small fry, and microorganisms. In the wild insect larvae make up a large portion of a guppies diet, and guppies even help control mosquito populations. Guppies even play a role in helping slow the spread of malaria in certain regions since they absolutely love eating mosquito larvae.
Brine shrimp (Buy Online) can serve as a good replacement for live insect larvae since it can be impractical to feed your guppies mosquito larvae in a home-based aquarium. It’s a good idea to feed guppies live baby brine shrimp once or twice a week, but baby brine shrimp do have a high fat and protein content, so they shouldn’t make up a large portion of your guppies diet on a daily basis.
Plant-Based Food
Do guppies eat algae? In the wild guppies have access to a wide range of plants and soft algae that they often pick at and graze on. Guppies will eat small amounts of soft algae in the wild, but by no means are they effective algae eaters. If you do have an algae issue, guppies usually won’t eat enough to control the problem, and there are better fish to handle algae in your tank like otocinclus and bristlenose plecos.
If you want to add some plant-based food to your guppies diet you can give them spirulina tablets periodically for them to nibble on. It’s also a good idea to keep guppies in a planted tank since they will pick at the algae that tends to grow on the leaves of the plants, and the plants will also give guppy fry a safe place to hide and some micro-algae to feed on.
Do Guppies Eat Flakes

Most guppies will readily eat flakes as long as they are small enough for them to easily swallow. Just make sure you get a tropical flake made for small fish since those types of flakes are made for fish with smaller mouths like guppies and neon tetras.
Sometimes you might have a picky guppy that just won’t eat flakes. Even fish can get bored of eating the same type of food every day, and adding some variety to their diet can help stimulate their appetite. In that case, you might want to try feeding them crisps or pellets.
If you’re looking for a good way to provide your fish a varied diet you can get the TetraMin 3-in-1 Select a Food (Buy Online), that contains flakes, pellets, and brine shrimp all in one convenient canister.
Guppies usually don’t need to be fed that often. Even though they might act like they are always hungry, it’s best to only feed guppies small amounts of food 1-2 times per day to keep them healthy and active. This will help reduce excess nutrients from causing ammonia spikes, and it will keep uneaten food from building up and rotting on the gravel.
Guppy fry, on the other hand, will need to be fed at least five times a day since they have smaller stomachs and faster metabolisms. Guppy fry should be fed a balanced fry food, or live food like baby brine shrimp, daphnia, microworms, and vinegar eels.
It’s best to feed guppy fry a small meal every three to four hours so they always have something to eat. While at the same time you still need to space out the feedings so they can digest the food they already have in their stomach
Guppy Fry Feeding Schedule
First Feeding – Baby Brine Shrimp
Second Feeding – Fry Food / Freeze-Dried Blood Worms
Third Feeding – Micro-algae / Crushed Spirulina
Fourth Feeding – Microworms /Daphnia / Vinegar Eel
Fifth Feeding – Fry Food / Crushed Tropical Flakes

Oscar Fish Water Parameters Oscar Fish Water pH Level Oscars prefer water with a pH between 6 and 8, but they prefer slightly acidic water and they can live in water that has a pH as low as 5.5 quite comfortably. Oscar Fish Nitrite Level The nitrite level in your tank should be at 0 ppm once your tank has cycled. Nevertheless, a weekly 10% water change with fresh water from the tap is always good early on in the cycle to reduce nitrites. Oscar Fish Nitrate Level To keep your Oscar healthy you want to keep your nitrate levels between 10-40 ppm. It's important that you test the water with a Nitrate Test Kit (Buy Online) to ensure the nitrate levels in your tank aren't reaching dangerous levels. If the nitrates in your tank stay consistently over 40ppm, it’s time to clean or replace old filters, clean out uneaten food, vacuum the gravel, and do at least a 25% water change. Oscar Fish Water Temperature The ideal water temperature for Oscars is 75-80 degrees Fahrenheit (23 - 27 Celcius). It's important to remember that Oscar Fish are from the Amazon Rainforest and they need a heater in their tank especially during the winter time If you want to know what size heater you need for your tank you can use our Fish Tank Heater Calculator (Click Here) Oscar Fish Water Change Water changes are an essential part of fish keeping for any type of fish. This is especially true when you have larger fish like oscars that produce more waste. Water changes, or partial water changes, should be done every 1-2 weeks depending on how many fish you keep in your tank Why Is My Oscar Fish Tank Cloudy Fish tank water can become cloudy for a few reasons. The most usual is that the aquarium is either experiencing a bacteria bloom or there is algae in the water column. If this is the case, you’ll need to do a 50%-75% water change immediately. You can also use an inline UV filter if water changes and regular tank maintenance aren't getting control of your cloudy water problem. How To Keep an Oscar Fish Tank Clean Water Changes Vacuum the Gravel Bed Cleaning the Filter Removing uneaten food from tank Check for any algae growth on plants or glass walls of aquarium and clean as needed Test the water regularly Do Oscar Fish Need a Filter Yes, Oscar fish need a filter because they are messy eaters that produce a lot of waste.
