Sign Of Overfed Guppy

Guppies frequently overfeed because they have such small bellies yet still consume big amounts of food when provided. Reduce the number of meals or snack times you give them if you observe any of the associated symptoms:

  • The waste tubes protruding from the fish’s belly indicate a bowel obstruction brought on by overeating.
  • Male guppies start to grow a “belly” or swollen breasts if they consume excessive fat in their diet.
  • The waste or leftovers cause the water in your tank to be frequently hazy and unclean.
  • Your guppies will have leftover food on them.
  • Constipation will affect your guppies.
  • Because of their swollen bellies, your fishes will sink to the bottom of the aquarium, struggling to stay buoyant.

For their well-being, guppy keepers should only give them food six days a week.

What Will Happen If You Overfeed Your Guppy?


Guppies who are overfed may develop some dangerous conditions:

Feeding Fundamentals

Guppies are not at all helped by being overfed. They should only receive the nutrition they require for proper growth when being fed, so you should feed them appropriate portions if you intend to raise them. 

In the end, a lot of food is squandered. It’s also crucial to remember that consuming too much food will not result in larger guppies.

Overfeeding and nutrient-deficient guppies are both undesirable scenarios. Guppies should reach adult size within the first month after birth. 

Overeating can destabilize their hormonal changes, especially during the first month of life.

Water Quality

The quality of your guppies’ water may suffer if you overfeed them, so consider stress and poor water quality thoroughly because they can cause health issues in fish

The last thing you desire is to let your fish live in an unsafe place where food is left unattended and collected on the ground, as leftovers and excrement can pollute water.  

Guppies can be susceptible to stress, which leads to hazards because it depletes their energy reserves. 

More than that, all inhabitants of a dirty aquarium risk being harmed and experiencing worry, anxiety, and discomfort.


Guppies will consume as much as they can, and this behavior frequently causes constipation – a common trigger of swim bladder illness. Both are capable of killing guppies.

How To Avoid Overfeeding Guppies?

If your fish has been overfeeding, there are some actions you need to take:

Set A Schedule

It’s recommended to skip treating your guppies the rest of the day if they have overeaten, which will enable their stomach to resume its normal course. Don’t feed them for an additional day if they continue to be swollen after a day.

Adult guppies are frequently fed every 12 hours. An excellent illustration would be to serve them in the morning and evening between 5 and 8 p.m. 

You can give them food at frequencies of ten or thirteen hours if this does work into your routine.

For fries, you should feed them every six to eight hours. Suggested feeding plan for guppies:

  • Feed them as soon as you wake up.
  • You should give them food: Before leaving for work and give them food when you get home or before going to bed
  • Additionally, you can spend money on a programmed fish feeder that allows you to feed them periodically.

Five Minute Feeding

The five-minute principle is a straightforward guide to feeding guppies the proper quantity. 

Never offer them more flakes, for instance, than you believe they can consume in a brief 5-minute time. 

Once the time is over, return immediately to the tank and work quickly to remove all of the remaining food.

Healthy Portions

Guppies benefit from a wide array of dietary sources, so healthy portions and nutrients are essential for maintaining your guppies in top condition. These omnivores function best when their diets contain meat, vegetables, and other suitable foods.

How To Prepare The Best Food For Guppies

Knowing how to prepare the food for guppies will help you a lot in maintaining the health of your fish.

Dehydrated Foods

Dehydrated foods, such as granules or dried insects, should be pre-soaked in water. They can then enlarge as a result. 

This action is crucial because when you don’t give the food enough time to expand and your guppies consume it, the food will enlarge inside their belly, causing overeating.

Once not adequately pre-soaked, dehydrated foods can result in congestion and bloating, which could sicken your fish. If the obstruction is extremely big, they might potentially pass away.

Fish Flakes

Fish flakes are good for guppies, as they contain a lot of good nutrition and are quite convenient for the aquarist. 

Remember to feed your guppy with just a small pinch of fish flakes daily. 

You can also make the fish flakes on your own. By doing this, you guarantee that no germs from raw food contaminate your fish.

Fresh Living Foods

Foods do not require processing, but they need to be fresh. Don’t give any dead animal to your guppy.

Insect and worm larvae are the greatest choices because they are the smallest and hence easier for guppies to consume, or the little shrimplings are also fantastic. Many experts advise giving your fish fresh and live food daily.

Frozen Foods

Frozen food can have various harmful consequences on fish if they eat it while frozen. So, make sure to defrost the food before feeding your guppies.


Aquarium guppies flourish when fed multiple times per day. Even though you may wish to give your pet a lot of food all the time, there are instances when it’s just too much. 

An overfed guppy can suffer from poor wellness and health due to improper food consumption, so keep this in mind!
