Deciding How, What and When to Feed your Guppies is one of the most important and fundamental aspects of successful guppy keeping. In order to master this ancient art of guppy feeding we must first understand mother nature and the relationship she has with her beloved guppy fish.


Question: How Often Should I Feed My Guppies & How Much?

  1. Fish Flake Food 3–6 times daily: 30 seconds until all food is devoured.

  2. Live Fish Food or Frozen Brine Shrimp 1–3 times a week.

  3. Natural Food Source within the Aquarium: Algae, Plants, Shrimp, etc.


Feeding small amounts frequently (3 - 6 times daily), only what the fish in the aquarium can devour within 30 seconds or less; stimulates the guppies & endlers livebearers drive to compete for food more often, supplying more blood flow, movement, and overall more chances in their life to get ahead of the future. When feeding fish flake; break the flake into guppy mouth sized pieces with your fingers as you drop it into flowing water. This helps the food spread equally amongst the colony so that eating food does not become a personal offense to the guppies and endlers space. Having naturally growing algae, plants, worms, mulm / detritus as well as a balanced community of neocaridina shrimplets inside the aquarium offers a guppy a steady income of food source for in-between feedings, evenings, and whenever you are not at home to feed or during a strategic fasting. This will create a biological threshold for the fish, basically a savings account of which the guppies & endlers can become attuned to, to live in harmony with.


Guppies are Opportunistic Omnivores


In the wild a guppy or endlers survival often depends on their ability to capitalize on the seasons. This drive is related to natural selection and is also why you can kill your fish by overfeeding. They are evolutionarily programmed with the radical ambition to constantly consume and there is nothing you can do to change this. Similar to a goat or a cow, guppies and endlers are constantly foraging whatever is available to them at all times, supplying a steady income of food from a number of natural resources, taking nothing for granted. Too many keepers make the mistake of feeding their fish when it suits them without considering that the consequences are counter intuitive to the benefits of keeping them.

In nature its often feast or famine, but even during famine there is always something they can depend on : Plants & Algae. Conversely, feasting can occur during a swarm of daphnia in the spring, black worms sticking out of the sand after a flood or even a fresh brood of baby shrimp in the foliage. Manufactured fish food is a wonderful resource and a luxury we all take for granted but knowing how much to feed and how often is very easily overlooked.

It is not natural for guppies to eat once a day, every day without the consequence of conditioning their behavior to more cannibalistic survival instead of thriving instincts, creating relationship community issues within the aquarium. I find that feeding small amounts more frequently; 3 - 6 times daily, only what the fish in the aquarium can devour within less than 30 seconds or less is found the be the most effective in breeding for numbers of fry and quality of traits and health. By feeding like this you are simulating a natural competition for food paired with ample opportunity, leading naturally to a thriving hierarchy. This is advantageous to anyone breeding guppies as it enhances the genetics, appearance, behavior and overall bond we have with our beloved guppy fish and the overall connection within the aquariums community.


A Guppies Diets Are Seasonal

Gluttony and fasting are not only natural, they are healthy and we should keep this in mind while maintaining biological homeostasis across the aquarium. We want whats best for our guppy fish, thus we get them the best food money can buy, culture all sorts of live foods and often feed them excessively, contributing to digestive problems in cold water; for example. Pizza is delicious but imagine if you had to eat it every night? Our guppies have evolved to synchronize their diets with the seasons and hence these changes often communicate to our fish instinctually when is the right time to procreate. Although their lives revolve around procreation & will breed regardless - there is a perfect time for everything, and the fish know what is most advantageous for them. Just how water changes emulate a seasonal rain or a flood / a freshening of the water column; alterations of the diet can also communicate a seasonal change advantageous to procreation. This is why fish breeders across the globe change water frequently and feed live food religiously for nearly every species they are so happened to be breeding. While live food comes and goes in the wild, algae and plants are always consistent to fall back on which is just one of the many reasons your aquarium should be heavily planted and some algae allowed as this is also a large source of their vitamin C. Read Vitamin C Deficiency Disease as this is a common issue people have with keeping their guppies, especially the delta class IFGA varieties with heavy ornamental tails that often effect posture and the overall mobility of the guppy.




Competition is vital to the evolution of the guppy fishes genetics, but in our aquarium we must consistently observe the overall conditions of our fish including their social hierarchy, colors, behavior, abdomens daily if we are to understand the species, genus and family of fish we accept to carry into the future. One thing that is common is the relationship between alpha males / females and their food intake. Often you will see the largest or most ambitious fisheys get larger bellies than other fish and while this is natural, it loads us with the ability to murder our fish by overfeeding if not done properly. Properly is spreading the food across flowing water so that it can disperse equally across the community, disregarding territorial disputes and instead turning feeding into a fun game for the fry which live peacefully amongst all of my colonies. Guppies and Endlers are very technically tropical fish and their behavior and metabolism effects appearances and overall health for the species. Venezuelan weather of the Cumana region tells us the ambient temperatures of the home of the endlers livebearers (poecilia wingei), where the temperature year round fluctuates between 73°F and 92°F. This is important for the species to have access to warm water for digestive and metabolic purposes that benefit the guppies feeding and fast paced lifestyle and therefore help your fish to avoid obesity, constipation or malnourishment where internal parasites can ruin. Heating up the water physically speeds the fish up such as the difference between a top dwelling fish and a dead sea creature can be seen visually. This speed requires energy, energy requires food, the food has to be digested & so the faster food can move through the GI tract, I believe there to be a decreased chance of internal parasites and ruin. Warm water is advantageous to their survival and its very consistently warm. If overfeeding first time mothers and when the fry drop it is common for them to have crooked backs, they believe that this is some type of genetic mutation. Although this can be true - through my experience, this happens most often to first time mothers as their bodies are discovering the perfect number of fry allowed per potential space in their abdomen to produce safely without deformity, and the over feeding makes this worse. I believe overfeeding a young guppy mother can aggravate this medical phenomena especially if not in warm water, so good observation of your guppies abdomen, color and behavior is paramount to the success of your guppy lines. Another thing to consider regarding gluttony; is your surface area of feeding proportional to the amount of fish you are feeding? Are you feeding all of your food in 1 square inch so that he with the biggest mouth can be fed? Or are you spreading the food out over running water so that is goes throughout the aquarium dispersing proportionally to community? When feeding multiple dogs or cats, it is best to space the food out and has an effect on the equal and fair distribution of food to the hierarchy without stress. Overall, not all food are created equal but all are necessary such as green algae for vitamin A, B1, B2, B6, B12, C and E and minerals such as potassium, iron, magnesium, calcium and iodine and complete proteins in the form of live food. Observing the abdomen is paramount to understanding and finding your homeostasis for your fish. Not all guppies or endlers are identical as their genetics move quickly and can change so rapidly in short periods of time to be acclimated to a completely different lifestyle(s) and or conditions as they are adaptive masters as we aspire to be.


Listen to the Aquarium


What do your fry, snails, plants, water and filters all have in common? They are all indicators as to what the proficiencies and deficiencies are in your aquarium. For instance one of the most commonly overlooked indicators of your success as a breeder are the number of fry that make it to maturity. Large fry numbers are the ultimate indication of happy guppies in a successful aquarium & happy guppies have a habit of being the most beautiful always consistently. Lets say you just started a new aquarium; you put in 1 male guppy and 5 females in & after 3 months only 8 fry have made it to maturity and you have witnessed the females being super aggressive. By the time you see the fry there are only 1-2 left; something is wrong and it could be your lack of consistent feeding tuned to the cravings of pregnant guppy, could be a lack of plants and cover for the fry to hide in a aquarium that is too small or it could even be the breeder you got them from was a cut throat cheapo that treated them to the bare minimum without empathy and they are stuck in survival mode. Quite often its all of the above. On the other hand lets say you start a new aquarium with 1 male guppy and 5 females; 3 months later you have 80 fry reaching maturity but you also have 100,000,000,000 snails, water is yellow, smells foul, algae is out of control; you have succeeded in feeding enough but at the detriment of your water quality ; a lethal eventuality. Its just like the world around us - were all connected and everything is an indication of another; cause and effect. Mother Nature has given us every indicator / resource an eco system needs to thrive which is why plants, algae, snails and shrimp are paramount to any peaceful freshwater aquarium.


Constant Food Source


Just as there are chickens on the farm, there should be shrimp & snails in every peaceful aquarium. Shrimp & snails are the greatest cleanup crew mother nature has to offer. Their services to the aquatic realms are immeasurable. They will devour anything that dies, plant or fish, eat excess food and turn right around and become a natural consistent food source for your aquarium (insert the Circle of Life by Elton John). The condition of your snails shell tells you about mineral deficiencies in the water, the amount of them tell you whether you're overfeeding. Shrimp are just like our guppies, extremely social, live to procreate and when they do, you're looking at hundreds of fresh tiny lobster tails running around for your fish (natural consistent food source). With a heavily planted aquarium you will have sufficient hiding spaces for guppy fry and baby shrimp to co exist with mutual benefits for the entire aquarium while offering a constant food source for years to come. Take no advice from Petsmart my friends, throw that painted plastic castle and breeder net into the trash and take your lessons from mother nature with a much more beautiful planted aquarium. I firmly believe that our Guppies & Endlers Livebearers entire life revolves around procreation. I find great honor in the responsibility of creating a working ecosystem in which they can live their lives to the fullest, and move their genetics to the peak. You are the driving force behind their world you have created & everything you do or dont do for them effects their genetics for better or for worse. Godspeed & may the current be with you.
