Do Betta Fish Poop? Why Can’t You See Betta Fish Pooping?

Betta Pooping

It won’t be wrong to say that you haven’t seen your Betta fish poop in the tank. So, in that case, you might be wondering if your Betta fish poops or not. Unfortunately, there is a very small hole right in front of their anal fin from where they excrete. Therefore, it becomes very difficult for humans to realize when their Betta fish are pooping. 

Over time, you will see a small build-up around their favorite toileting spot around the tank. You cannot immediately notice their poop every day, as they are very small and next to invisible. Unless they accumulate at one place to build up a pile, you cannot realize that your Betta is even pooping. 

The Pooping Habits of Betta Fish

Betta fish are secretive poopers. They want privacy while pooping and pick a specified spot around the tank. They mostly pick the area that is well planted or head out to the corner of the tank. So, the next time you see your Betta fish heading straight behind the reeds or live plants, they are not just wishing for alone time but for poop time. 

Poop or Pellets?

At times, with this lack of visibility for the Betta pooping, you might think that your fish isn’t eating anything and is therefore not pooping frequently. But this is not the case. Most of the time, Betta poops look just like the food they have eaten. Therefore, if you frequently spot the food items sunk to the bottom of the tank over the pebbles, then they might not be  food pellets but Betta poops.

Knowing the poop color and shape, you can eventually distinguish their excreta in your tank of multiple fish. 

Colour and Shape

Betta poop is not the same as any other fish poop. The fish poop of others is easy to identify, as they are probably the long brown stingy goo that excretes from that of the anal canal of the fish. But the Betta poop is more pellet shaped and is mostly reddish-brown. It always stays at the bottom of the fish tank. 

Betta Fish Poop Size

Even though Betta poop looks similar to  food pellets, the size of these droppings is small. Therefore, you need to keep a keen eye on the tank to spot the single poop amongst everything else within it. But as Betta fish goes to poop to only one place within the tank, it becomes easy for you to take note of a pile of poop or solid build-up, rather than looking for single and small droppings.

The food that is present within the excretion is not ingested by the Betta or eaten by parasites. If there is a parasite problem, the entire tank needs to be cleaned up, and your fish needs medical attention. 

Watery Brown Poop

Watery brown poop is when Betta fish expels more water from the pooping region than the pellets. If that is the symptom, it indicates diarrhea as the prime problem. It is a brownish white watery poop that vanishes away in the water. Therefore, it becomes hard to spot, but you need to look for it if you haven’t witnessed any pellet poop in 12 hours or more. 

Bad Diet or Bad Infection?

The fish don’t need to be going through some health problems in response to a change in poop color. A change in diet routine or introduction to a new treatment might change their poop color, completely normal. 

But if you haven’t made any diet changes, haven’t given them new treats, and their food has no added colors, but still, they have changed poop color, then it might indicate some health problems. Such signs include black poop, red poop, or sudden other color changes. 

Why Is Your Betta Fish Not Pooping?
