Reasons why guppy is not eating?
There can be various reasons behind your guppy not eating food. However, some of the most common reasons for guppy not eating food are:
- Poor water condition
- Low or high water temperature
- Expired food
- Your guppy is sick
- Your guppy is in labor.
- Bored of one type of meal
Poor water condition
Inadequate water conditions can be the leading reason for your guppy not eating their food. Therefore, we recommend at least 50 percent water change on a weekly basis.
Not changing the water can spike ammonia, harmful bacteria, and a poor oxygen source for your guppy.
All these problems will make the worst environment for your guppy to live by a time.
Soon, your guppy will start showing changes like losing appetite, or they will get sick. Also, a spike of ammonia will make your guppy breathe in ammonia or swallow things that have a large amount of ammonia, resulting in ammonia poisoning.
These are some signs which will make you know that your guppy is going through problems:
- You will see physical injuries
- Your guppy will lose its appetite.
- You will find your guppy losing color, or there will be a visible stain or mark.
- Your guppy will gasp for air near the water surface.
- Clamped fins as a sign of parasitic infection
Changing the water regularly and installing a good filtration system will prevent all the above problems and your guppy.
Low or high water temperature
Guppy will not feed on food if there is a low temperature, as the low temperature will lower the metabolism level of your guppy, and your guppy will not eat food in such a situation.
Your guppy will also not feed on food if there is a high temperature. Guppy will need their ideal temperature for being normal and destress as low, or high temperature will make them stress out.
Feeding expired food to your guppies is not a good take. However, guppies will feed on expired food if you will not give them much of an option, but many of them will avoid eating the expired food as much as they can do.
You will see your guppy not giving much of an interest when you serve them food. Your guppies will nibble on the food but will not completely eat it.
You will find it by the food left as waste by your guppies.
Your guppy will not show these kinds of behavior before there is any problem going there.
So, after seeing this behavior, all you have to do is find out the reason behind it. Look if food is the actual problem or there is some other problem your guppy is facing.
There can be various reasons behind your guppy only nibbling on food and not eating it. For example, your guppy may have lost its appetite, is sick, or inadequate water condition is why your guppy fish is not eating anymore.
You can know if your guppy is going through any of the above problems as there is a sign like an odd swimming pattern or showing no interest; your guppy will be less energetic and show signs of illness.
If you find out that none of the above problems is why your guppy is not eating, go for the food you are providing your guppy.
Make sure to provide your guppy with good quality food. Always purchase food from the reputed stores that keep good quality food rather than cheap quality food.
If you are feeding your fish commercial-grade food like pellets or powdered food, look out for the quality of food in the first place.
Live food is the best food to prevent your guppy from any food problems.
Your guppy is sick
Guppy with sickness will affect the normal behavior of your guppy. For example, your guppy will not eat if they are sick and going through some problems.
There are various illnesses from which your guppy can go through; some of these are
- White spots
- Fin rot

Remember that if this disease is not treated early, it can also be a critical condition for your guppy.
Tail, fin rot
The bacterial infection causes fin or tail rot. Also, the fungus that grows on the nibbed fin can explain the rotten fin and tail. Inadequate water condition and ammonia burn can also be the reason for rotten tail and fin.
If the fins and tail are not damaged but have started rotting, it is because of bacteria, and if the fins and tail are damaged and are rotten, then it is because of the fungus.

Stress can also be the reason for your guppy not eating.
Now, your guppy can get into stress because of various reasons:
- Whenever you bring a fish from the fish shop to your home, your fish get stressed out because of unusual movement, and it takes time to get back to normal after moving them into your aquarium. So give your guppy some time to be normal.
- Whenever you clean your aquarium by changing water or using the fishnet, your fish get into stress for some time, and at this time, they will not eat anything you serve.
- Disease or injury can be the reason behind your fish not eating food.
