Have you ever had a goldfish swim upside down? Find that their belly appears bloated, or that they seem especially lethargic?
These are all signs that your once-healthy goldfish may be having serious digestive issues, which can mean constipation or potential illness.
Treating constipation in goldfish can be a complicated process, as it can stem from a variety of causes.
If you’ve ever seen the symptoms of a constipated goldfish and wondered what to do, read on for how to determine the exact cause and treat it.
What is Goldfish Constipation?
Much as people on the surface, constipation in goldfish and other fish species means that they are unable to process or pass feces through their body. This can be incredibly painful if untreated, and leads to a wealth of other problems down the road.
NOTEGoldfish metabolism plays a critical role in how easily your fish’s body is able to digest and pass food. Older fish, or those already suffering an illness will have a lowered metabolism and a harder time passing food through their digestive tract.
Goldfish constipation can be caused by several different factors, including diseases affecting the digestive system such as fatty liver or fin rot, overfeeding, or the goldfish’s diet being unbalanced.
The key to determining just what is going on and treating constipation comes down to isolating which factors are off in your particular tank.
Can Goldfish Die Of Constipation?
If you are unable to treat your fish for constipation and change your feeding to reflect this, your fish may indeed die.
As with other animals, not being able to pass feces can cause a buildup of toxic waste inside of their body as they feed, leading to deadly toxic shock or sepsis.
With proper treatment and feeding, your fish should return to normal within the course of as little as a day after passing waste.
How Long Can a Goldfish Remain Constipated?
Given that it can be hard to determine exactly when in your normal feeding schedule that your fish has started the process of constipation, it can be difficult to answer this question.
If you continue to feed as per usual and food continues to accumulate in their system, the constipation can begin to wreak havoc on the normal bodily functions of your goldfish in as little as a few days.
When it comes to fatality, it may take between a few days and weeks for constipation to reach a lethal level and poison your fish.
That being said, if your fish is already being fed an inadequate diet and water parameters in your tank are off, that process can be expedited.
Signs of Goldfish Constipation
There are several important signs and symptoms to look out for when trying to notice constipation in your fish.
While most of these are somewhat more obvious in nature, it is up to the aquarium owner to know the normal behavior and feeding patterns of their goldfish.
Stringy Feces/Long Poop
This is actually a sign that your fish has not been feeding regularly.
While some may think that something is wrong with the food inside of their fish, this is an indication that the bowel movement does not contain any actual food.
Not to mention, if your fish is able to pass stringy feces or long poop in the first place, it is likely not suffering from constipation. You may see this as a white coloration or in the color of the pellets that you typically feed your goldfish, and it’s a part of regular life for a fish to pass poo this way.
Not Passing Stool
While it may be hard to notice unless you are able to monitor your goldfish fairly consistently, not passing stool at all is essentially the definition of constipation.
Fish suffering from constipation will be unable to pass any sort of material until they have been treated and are able to properly digest their food again
Lack of desire to eat can be a major problem for your fish. Noticing after a day or two that they do not consume any food may be a sign that constipation is the culprit.
However while this can be one of the symptoms of constipation it there are many other illnesses, diseases, and issues that could be the case in what exactly is affecting your fishes.
In some instances, having your goldfish stop eating is less a result of constipation and more of a sign that they have had enough food and need more time to digest.
Constipation in goldfish can be a tricky thing to diagnose on one’s own and it is best left to a professional.
The term dropsy comes from an old English medical term for swelling in the abdomen caused by gasses or fluids. The “drop” refers to the way the belly of the fish appears to droop in appearance as it swells.
Today it would more likely be referred to as an edema, but either way it can lead to serious health complications in goldfish.
Signs of a Goldfish With Dropsy
Swelling around the eyes, bloated stomach, the presence of lesions, scale loss, or abrasions, and becoming lethargic, constipation, or acting excessively tired and swimming in irregular ways
Dropsy is caused by a group of several bacteria commonly present in most home freshwater aquariums.
An unstressed, healthy fish can handle the presence of these bacteria without much problem. Unfortunately, by the time the more serious symptoms of dropsy begin to manifest it may be too late.
Treatment for Belly Bloat
Treatment for bloat can be difficult and require medications or the use of aquarium salt, but a good place to start is by removing the afflicted fish to a separate tank to prevent dropsy from spreading.
Swimming in an unusual manner (upside down, exclusively on the bottom, or at the top of the tank) may be a sign of constipation in goldfish.
Additionally, this can indicate that a number of things may be wrong with your goldfish, from issues with the swim bladder, to parasitic infection.
Constipation may not be the immediate cause, but if you notice that your goldfish is swimming oddly in addition to not having passed waste for some time constipation may be to blame.
A goldfish that is constipated will likely exhibit symptoms of lethargy, swimming around slowly or not at all as their body attempts to pass undigested waste.
Noticing a gold fish moving sluggishly could also indicate that the water in your aquarium is too cold, or that they have in fact not had enough food and may be tired or sluggish as a result.
Air Bladder Disease
Seeing a goldfish having trouble swimming can be a sign that something is wrong with their swim bladder.
Swimming upside down, moving awkwardly, or being unable to swim are all signs that something may be off with the air bladder of your goldfish, which is meant to control their movements throughout the water column.
What Causes Constipation In Goldfish?
There are several distinct possible culprits that can lead to constipation in goldfish.
Some of these are harder to detect, such as disease, while others such as providing a balanced diet may be much easier to treat for the home aquarium.
Goldfish are omnivores, meaning that they require a balanced intake of both proteins, fiber and plant-based nutrients.
Ensuring that your goldfish’s diet is well balanced and provides them with the right set of fiber and nutrition is the best way to prevent constipation in goldfish.
NOTEIn a pinch, you may notice your goldfish eating the plants in your aquarium to try to get more fiber and nutrition..
Checking in with your veterinarian of choice, along with the pet store or breeder from which you initially purchase can provide great guidance on just what you should be feeding your goldfish.
Many stores sell specially-formulated foods specifically for goldfish, which contain the balance of vitamins and minerals, and fiber that they would be otherwise unable to get.
NOTELooking at the ingredients for most formulated fish foods will show you that they’ve got about the same amount of fiber as peas, around 5%. The reason for this is because goldfish digestive systems aren’t meant to digest too much fiber at one time, seeing as they wouldn’t consume peas or fibrous vegetables often in the wild.
Feeding your fishes too much food can lead to a blockage in their digestive tract, causing constipation. Even with the fiber from pellets or plants, overfeeding can wind up with your goldfish becoming constipated.
Remember that your goldfish will typically feed as much as it can in a given session and plan to feed them only as much as they need.
NOTEEven if your goldfish aren’t overeating and becoming constipated as a result, having excess pellets or flakes can cause the tank water to become contaminated. A good rule of thumb is to remove uneaten food within a half an hour of feeding in order to prevent excess ammonia buildup which can potentially poison your goldfish if left unchecked.
Allowing your goldfish the proper amount of time to pass the extra food that they have consumed may help if they can end the constipation on their own.
However in some extreme circumstances if symptoms progress, they may need surgery in order to remove the blockage and become un-constipated.
Given that we cannot necessarily encourage our fish to exercise regularly, an unhealthy or unfit goldfish can be hard to treat.
If you notice that your goldfish tends towards sloth, perhaps consider adding in more interesting decorations or slightly increasing the water flow or adding air bubbles in your tank to encourage them to move more and get the food moving through their system to ease constipation.
Swim Bladder Disease
The swim bladder is the air filled organ in a goldfish that allows for movement throughout the tank.
When your fish gets swim bladder disease, this air becomes either too concentrated or may dissipate, leading it to either sit on the bottom, float awkwardly around, or your goldfish swimming awkwardly in the tank.
Swim bladder problems can be incredibly difficult to deal with for the fish itself, as they’ll have difficulty eating and reaching their food.
A swim bladder issue can quickly change from simple swim bladder issues into malnourishment and further illness if not properly treated.
Swim Bladder Treatment
To resolve swim bladder issues, consult your veterinarian or local pet shop if there are serious symptoms such as trouble breathing or being unable to swim altogether to determine which swim bladder disorder medication is right for your fish.
A good first step in controlling swim bladder disorder is to move the sick fish to a quiet, isolated tank so that it is not further stressed and can’t introduce illness to fish in the betta tank.
The Water Is Too Cold
As the water temperature decreases, so too does the metabolism of your fish which can lead to constipation in your goldfish at drastic levels.
Goldfish are a cold water fish that prefer temps between 50 and 60 degrees Fahrenheit, and lowering the temperature below this can cause their bodies to slow down.
If you notice that your tank temperature has become too low, consider the use of a heater to ensure that your goldfish does not become constipated as their digestive system slows.
What Should You Do If Your Goldfish is Constipated?
If you find that your goldfish has become constipated, a good first step is to consult with a veterinarian. They will be able to properly diagnose the symptoms affecting your goldfish and causing the constipation, so that they can help you treat it.
In any case, this helpful video will give you an idea of what to do if you notice your goldfish is constipated.
NOTEAs with many goldfish issues such as constipation, consider removing them to a separate quarantine tank. This will allow your goldfish to recover from constipation in isolation and avoid the spread of whatever potential illness or bacteria may be causing it.
Check the conditions within your tank, and think back to how you normally feed your goldfish to determine if something has changed recently that may be causing the constipation. Changes in diet or water condition can be the likely culprit.
Make sure that you do not stop feeding them! If they do not actually have constipation, refusing to provide food to your goldfish will only make matters worse.
How To Treat Constipated Goldfish
There are a few guidelines for treating constipation in goldfish. In general, working on the water quality in your tank should be the priority.
If your fish is suffering from some unknown illness, performing frequent water changes of 10-25% will be much more effective than simply having them eat peas or using epsom salt.
Adding shelled peas to your fish’s diet can help aid with digestion. Peas provide a relatively small amount of fiber to the diet, but can ease the symptoms of a constipated goldfish.
Peas generally act as a mild laxative, and if you feed a pea to your goldfish it may provide just enough fiber to help symptoms pass.
Should you choose to add peas to their diet, consider starting small with one pea at a time to ensure that they will actually eat them. Adding more peas than they’ll eat at any one time can simply add to the problem!
Along with a balanced diet, a good technique in your goldfish first aid kit, the use of salt to aid in fighting off constipation is a good one.
While referred to as an “epsom salt bath,” this technique is more used to assist the entire tank with ammonia poisoning or disease control, along with the symptoms of constipation.
When we refer to aquarium salt, we typically think of table salt, or NaCl. While this may be more readily available, it isn’t the best choice for our home aquarium as it often contains iodine and anti-caking components that can make it potentially harmful for your betta fish.
NOTEAs epsom salts can act as a natural laxative for your goldfish, an epsom salt bath can be a good way to help them pass any undigested materials or peas out of their system and end constipation.
Therefore we recommend epsom salt baths as a safe way to help fight off infections and diseases such as dropsy, along with aiding your constipated goldfish.
Throughout today’s article, we’ve looked at the effects of goldfish constipation, its causes, as well as some potential ways to treat it.
The key factors are providing a varied diet for your goldfish and monitoring your tank as a whole, so that you know how conditions are and prevent poor water quality along with regular partial water changes to keep things fresh in your tank.
Identifying symptoms can be the greatest challenge in helping your goldfish return to its healthy self.
