Where do betta fish poop come from?

In this post, we will answer the question “Where do betta fish poop come from?”. We will also discuss some characteristics that require some attention for your betta fish health.

Where do betta fish poop come from?

Bettas have a little hole in front of their anal fin where they poop. You won’t notice your Betta fish pooping until you observe a build-up in their chosen toileting spot since its waste is so little. 

Bettas are sneaky poopers that hide their feces. They prefer to do it in the same place every time, with a little privacy, and they usually do it in a wooded area or a corner. So, if you believe your Betta is simply seeking solitude in the reeds, think again! They’re most likely pooping. 

Poop or pellets? 

Betta Fish owners commonly feel their fish isn’t eating or pooping since their excrement looks like their food. It’s conceivable that the ‘meal’ you see in the bottom of the tank isn’t pellets.

Diet for Betta Fish 

If given a balanced diet and the proper amount of food, betta fish will defecate around 5 or 6 times each day. Bettas eat as if it’s their last meal since they never know what will happen in the wild. As a consequence, it’s easy to mistake this survival instinct for hunger and overfeed your Betta Fish, perhaps resulting in health issues. 

Your Betta fish will be healthy and their poops will be consistent if you feed them according to the food manufacturer’s instructions and keep their tank at the proper temperature, which is between 74 and 82 degrees Fahrenheit.

How do Betta fish poop?

It might be difficult to keep track of which excrement belong to which fish if you have a lot of different species in your tank. To maintain track of your fish’s health, it’s a good idea to keep an eye on their excrement. Any changes in the colour or consistency of fish excrement could mean something is amiss. 

Betta feces is distinct in colour and form from that of other aquarium fish. Fish excrement is typically identified as a lengthy dark stringy gunk secreted from the fish’s anal canal. Betta feces, on the other hand, has a pellet-like shape, is reddish-brown, and settles toward the bottom of the tank. 

Betta excrement resembles the food they consume; however, the colour may differ slightly from that of pellet food, indicating that you are looking at fish waste rather than a squandered meal. 


Betta excrement looks a lot like food pellets, although their droppings are still rather little. It takes a trained eye to identify a single poop among everything else in your fish tank, but because Bettas prefer to defecate in one spot, it’s easier to check for a cluster of excrement than single droppings. 

What can you tell from your Betta’s poop If something is wrong with them? 

If your Betta Fish’s excrement is anything other than pellet-like and reddish-brown, it’s a sign that your fish could need some assistance. 

Bettas, like humans, can have constipation, diarrhea, and other stomach issues, which can influence the appearance of their waste. As a result, you can monitor your Betta’s health by looking at their excrement. 

If any of the following describe your Betta’s faeces, they may be sick and require medical attention:

Poop with Strings 

Constipation may be indicated if your Betta is passing stringy dark feces rather than pellet-like feces. Contrary to popular perception, fish can become constipated and dehydrated if their food is deficient in water. Overfeeding is the most common reason. 

Although it may seem strange that fish can become dehydrated when they are continuously surrounded by water, constant food intake can result in a dehydrated Betta Fish with constipation. 

Poop with a large globular shape 

Constipation in Betta fish can also be indicated by large globular excrement. It could be an indication of dehydration or overfeeding if your fish’s excrement is larger than the usual particle size. 

Constipation is inconvenient for your Betta, but it is treatable and avoidable. Make sure your Betta eats a good diet, gets lots of activity, and eats the correct quantity of food.

Exercising your Betta fish 

You’re probably wondering how to get your Betta fish to exercise more to relieve constipation. You can’t, of course. Swimming around their tank is how fish get their exercise, and it’s a natural behaviour for them. 

However, if your Betta fish is sluggish and not moving around in its tank on its own, it could be an indication of something else. Constipation caused by inactivity might be a symptom of something else in a sedentary Betta fish.

Poop that is white or pale

If your Betta is eating normally but has white, pale, and stringy excrement, it could be a sign of parasites, and you should have your Betta fish examined right away. 

White feces in fish is poop that hasn’t been fed. If your Betta is pooping white, it’s mucus from their digestive tract, and the food that should be there has either been eaten by internal parasites or hasn’t been ingested at all.

If your Betta has parasites, you’ll need to clean and treat the entire tank, as well as maybe take your Betta to a vet for medicine. 

Is it a bad diet or an infection? 

Diarrhea in Betta Fish can be treated, and the severity of the diarrhea is determined by the cause. Diarrhea might be a sign of an unhealthy diet. Either the food you’re feeding them is of poor quality, or they’ve been overindulging in treats. Your Betta fish should be back to normal after altering their food and minimizing rewards. 

If your Betta fish is eating well but still pooping water, it might be a bacterial or viral illness. It is preferable to take your Betta fish to a veterinarian for diagnosis and treatment.

Betta fish poop colour: What should it be? 

Although the colour of Betta excrement is frequently described as reddish-brown, it can range from dark brown to tan to off reddish. Betta food may contain food colouring, which may alter the colour of their excrement. Betta food has no food colouring, so there’s no need to be afraid.

Your Betta’s excrement can range in colour from red to brown to tan, as long as they’re fed a high-quality brand of food at regular intervals. Their excrement will retain the same colour if you feed them the same diet every day.

Do different poop colours indicate different issues? 

Several causes could cause changes in the colour of your Betta Fish’s excrement. Colour changes are common and might occur as a result of a change in routine or after giving them a new item to eat. 

If the colour of your Betta’s excrement changes and you haven’t given them any treats or altered anything about their routine care, your fish may be unwell and require medical treatment. 

Although Betta Fish faeces might be difficult to differentiate from uneaten food pellets, tracking your Bettas’ waste and analyzing any colour changes is suggested in case your Betta Fish becomes unwell.

What if the poop colour shifts suddenly?

You may notice a variation in colour in your Betta’s poops if you switch brands since various manufacturers use different chemicals, but it should always be within the spectrum of tan, brown, or reddish-brown.

Red poop

If you feed your Betta fish particularly red food, you should expect bright crimson excrement. If the food you’re feeding them isn’t red, you should consult a veterinarian. Betta’s vivid red excrement isn’t unheard of, but it’s not common. 

Black poop

The presence of black excrement in some Betta Fish is not a cause for alarm. Black poop is frequently caused by a combination of variables, such as the food you feed your Betta and the cleaning agents you use. 

Why Doesn’t Your Betta Fish Poop? 

Betta fish poop 5-6 times per day on average, and anything less could indicate that something is amiss. 

Constipation with no poop is also a sign of serious constipation. Keep an eye out for these additional indicators that may aid in the diagnosis and treatment of your Betta Fish. 

Stomach Swelling 

In Betta fish, a large stomach can indicate diarrhea, but if your fish isn’t passing brown water or any excrement at all, a swollen stomach could indicate severe constipation. 

Swim Bladder is a condition caused by severe constipation. This occurs when your fish’s stomach swells and presses against the swim bladder, producing buoyancy issues. If this is the case, you should stop feeding your fish for 1-3 days to let the food flow through and their digestive tract return to normal size. Consult a veterinarian if this doesn’t work. 

Epsom Salts are a kind of magnesium sulphate 

You may have heard that soaking your fish in Epsom salts is good for their health, and this is true in most cases. Epsom Salts, on the other hand, can be harmful to Betta Fish. 

To cure disorders like dropsy, give Betta Fish an Epsom salt bath once or twice a week, although the salts can be harsh on their digestive systems and cause difficulties if exposed for too long.

If you gave your Betta an Epsom salt bath lately and they aren’t pooping right now, it might be the salts, and they should be OK in a day or two.

Poop from Betta fish floats? 

Poop from a healthy Betta Fish does not float. If your betta’s excrement is healthy and normal, it will always settle to the substrate of your tank. 

Betta excrement is elongated and neither buoyant nor stringy in appearance. If your Betta’s feces floats, it might mean he or she has a health condition.

Frequently Asked Questions (FAQs): Where do betta fish poop come from?

Is Butterless present in betta fish?

Betta fish eat with their mouths and then crush it up with their teeth. The nutrients from the broken down meal are absorbed in the intestine. Any waste is expelled from the stomach via the anus, which is placed behind the ventral fins and in front of the anal fin.

What are the signs that your betta fish is pooping? 

Because most fish owners are unable to keep an eye on their fish 24 hours a day, your fish is likely to poop during the day or overnight. Rather than checking for feces on your fish, try looking at its surroundings. Fish feces is typically lengthy and stringy, with a brown or black tint that resembles the colour of the fish’s meal. 

Why does my fish have excrement hanging from it? 

Bloating and the formation of stringy feces are signs of constipation in fish. Constipated fish feces are stringy and dangle from the fish, whereas normal fish feces sink to the substrate quickly. Constipation affects a fish’s ability to get rid of feces, not how much it produces. 

What happens when fish poop? 

Fish use their gills and skin to pee and defecate. Some people may pee and defecate through a pore, which is a tiny hole at the rear of the body.

How to stimulate your Betta fish to poop?

Keep an eye on the fish as it is being fed to ensure it is eating. If your betta is still refusing to eat, try live brine shrimp or freeze-dried treats like bloodworms. This will frequently tempt a fussy betta to eat, as well as cause the betta to poop regularly.
