Do betta fish poop?

Yes, bettas poop from a small hole in front of the anal fin. Their poop is quite small, so you probably won’t notice betta fish pooping until you spot a cluster at their favorite spot.

Like us humans, bettas have a gastrointestinal tract too and  pooping or defecation is considered the only way to remove food waste from their body.

Bettas have a tiny stomach, so bettas poop are generally relatively small. Betta that are regularly fed will poop regularly, but don’t worry if you don’t see the poop of betta fish every day.

Betta poop tends to be harder and rounder than long and stringy, so it is often mistaken for an uneaten betta pellet.

Poops of healthy betta are brown and gloomy. Globes that are larger than usual can be a sign of constipation.Changes in fish droppings or poop color and consistency may indicate something is wrong.White, long, thin thread-like poop may be a sign of endoparasites.

Most fish owners are unable to monitor their fish 24 hours a day, so your fish are likely to poop during the day or overnight. Instead of looking for droppings on your fish, try examining its surroundings.

What is the shape and color of bettas poop?

The feces or poop of fighting fish are usually round and relatively small. It should be brown or yellowish brown. Betta feces can also have a red tint, mainly due to the dyes used in betta food.

If your betta fish’s poop is white or yellow, this may be a sign that your fish is sick.

How often do a healthy betta fish poop?

Bettas typically poop 5-6 times a day, less than this may indicate a problem.

Frequency may decrease or even stop temporarily if they refuse to eat due to sickness or constipation or other health reasons.

The absence of bowel movements is also a sign of constipation, which can be very serious.Watch for other signs that may help diagnose and treat betta.

Are bettas picky about their poop spots in the tank?

Like other pets, bettas are attracted to pooping in the same common place.Most waste is often in one place, unless strong currents or other tank mates are disturbing the bottom of the tank.

Betta fish are also picky about being somewhere safe when they defecate, often near a planted area for privacy.

What are the types of betta poop?

Types of betta poop are:Their poop can be tan, brown, reddish, or black,depending on the food you are feeding your betta fish.

  • Pale or white betta poop
  • Watery brown betta poop
  • Black betta poop
  • Stringy betta poop
  • Red betta poop
  • Yellow betta poop
  • Large globular betta poop

Pale or white betta poop

If betta is eating normally and passing white, pale and sticky poop, it may be a symptom of stomach parasites and you should check your betta immediately.

White stool infected with endoparasite imitates dancing against the stream of water. This is a clear sign of an infected worm infestation.

Watery brown betta poop

This is a sign of diarrhea if your betta fish is expelling water from the anal canal instead of pellets.

The faint brown water disappears quickly in the aquarium, so it’s hard to find, but be careful if you don’t notice the fresh betta fish poop pellets in about 12 hours.

Black betta poop

A few betta fish may have black poop, but this is not a problem. Black poop is usually the result of a combination of elements such as bettas food and products used to clean their aquarium.

Stringy betta poop

If your betta poop is brown but sticky rather than granular, it could be a sign of constipation.Bettas don’t understand how much they should eat to stay healthy. As a betta owner, you must know this for them.

If you overfeed a betta fish, their stomach will expand and when that happens, it pushes their swim bladder and after that, the betta fish will have problems with swimming.

Therefore, frequent feeding can affect their health. So give your bettas the right amount to keep them in good condition.

Red betta poop

If the food you feed your betta is too red, bright red poop may appear. If the food you give them isn’t red, then you may need to talk to your veterinarian. It’s not uncommon for betta fish to have bright red poop.

Yellow betta poop

If betta fish are constipated or have other indigestion or parasitic infections, such as Camallanus worms, their poop is yellow.

Yellow stool from a fighting fish is a clear sign that your fish is not well. Try vegetables first, such as shelled green peas.If this does not solve the problem, you will have to feed them antiparasitic food.

Large globular betta poop

Large, ball-shaped/globular stools can also be a sign of constipation in a fighting fish. If your betta fish’s poop are larger than normal pellet size,this could be a sign of dehydration and overfeeding.

Do bettas poop disintegrate?

Don’t panic if you haven’t seen your betta poop in a while. Fecal residue breaks down quickly when mixed with bottom gravel, so you may not even see signs of consistency.

Why doesn’t your betta poop?

Overfeeding can lead to blockages that can stop food from moving through the gastrointestinal tract.

In many cases, your betta will continue to eat without any pooping and their abdomen will swell.

Betta fish owners are sometimes confused between pellets and poor and tend to believe that the betta fish does not eat much or defecate at all.This is because their poop looks a lot like their food.

Therefore, if you notice food that has fallen to the bottom of the aquarium, it may not be pellets.

Does bettas poop change water chemistry?

Yes, bettas poop do alter their water chemistry. Like all living things, betta fish excrete waste products (urine and poop). This nitrogenous waste breaks down into ammonia, which is highly toxic to betta fish.

Bettas are very sensitive to the water quality in the aquarium, so proper handling is very important.

Do bettas poop float or sink in the substrate?

No,healthy betta fish poop will not float in the aquarium water. If betta’s poop is healthy and normal, it will sink to the bottom of the aquarium every time betta poops.

The poop of betta fish is elongated in shape and is not buoyant or thread-like. If your betta is excreting floating poop, it may be a sign of a health problem.

Do betta fish excrete bloody poops?

Yes, your betta fish can emit bloody mucus, but it’s rare and can be deadly. Coccidia is a parasitic infection that may be the cause of bloody stools in betta fish.If you notice blood in your fish’s stool, see your veterinarian right away.

How to clean bettas poop from the aquarium?

The only way to remove betta fish excrement or poop is to use a gravel vacuum and remove it by hand.

A gravel vacuum will be the best and easiest way to do a quick cleanup on a regular basis.

Vacuuming the gravel weekly will remove most of this debris and freshen up the aquarium, brightening the gravel and keeping the aquarium healthy.


Betta poops through a small hole in front of the anal fin.If you feed your bettas a similar amount and they eat regularly, they will also have regular bowel movements.

Bettas like to poop in the same spot with little privacy, and they tend to choose a spot with plants or a corner to poop.

Betta poop looks like food pellets, and their droppings are still rather small.

If they refuse to eat, become constipated, or get sick, the frequency of pooping may drop or even stop for a while.

The feces or poop of the fighting betta are not like the feces of most other aquarium fish. The feces/poop of betta fish are granular, reddish-brown in color and remain at the bottom of the aquarium.
