Why do fish take so long to poop? Fish will take too long to poop because their digestive system often becomes jammed with the food they pick up from time to time. It can take several days for fish to digest complex food, which means they poop and pee once digestion is completed.

What color is Fish Poop?

Fish poop can vary in color because they comprise of waste products that are being eliminated from the body. Waste products contained in fish poop will include the undigested particles of food, salt, and bacteria.

Aside from varying color, fish poop can vary in texture, volume, and odor. Normally, the fish poop will take the color of the food they have been eating for a while.

For instance, fish fed with flakes in the aquarium will usually produce reddish color poop, and the reason being that flake foods contain lots of blood worms.

Fish that are fed with peas will usually excrete greenish-color poops. The darker the peas, the greener the color of the poop. Sometimes, extremely dry fish foods can cause long, trailing poo that is somehow compacted.

When a fish starves, the color of the poop can be whitish and clear, and in some cases, it may appear brown.

How Often do Fish Poop

Fish will normally poop as often as they can or when there is urgency or need to eliminate waste from their bowels. If you feed your fish similar quantities of food on a regular basis, they will poop on the same regular frequencies.

Fish that are fed constantly will poop at least once in every 48 hours. Those that are not regularly fed will poop at irregular intervals and their poops are often delayed. In many cases, starving fishes wouldn’t poop for up to 4 days.

Peeing is more constant than pooping in most fishes. Fishes do pee almost on a daily basis, depending on how well their kidneys function.  Fishes will also poop less when they are sick, but you don’t have to worry about checking their bowel movements if they are not sick.

Is fish poop good for plants?

Fish poop is good for certain plants such as the coral reef that require nutrients, sunlight, and clear, warm water to survive. There are insufficient nutrients in the water for coral reefs to survive but they get enough from pee and poop from fishes.

When the fish pee or poop in the water, for instance, the coral reef will wave their tentacles around their tiny arms to grab the pee and poop and then absorb nutrients from them. A number of other water plants also grab nutrients in like manner.

Water plants and corals are able to get essential nutrients such as Nitrogen and Phosphorous from the pee of fishes. It is the nutrient from this pee that helps coral grow slowly.

Algae is another group of plant, known for absorbing nutrients from fish pee and poop. Algae are known to convert certain nutrients in pee and poop of fishes into sugar.

What is fish poop called?

Though, many people will refer to fish poop as “Detritus”, this scientific name, however, is a general term for the dead particular organic substances originating from fish. It may include the fragments or dead matter of fish organisms, and the fish fecal materials.

Do Betta fish poop?

Do you often find it difficult to tell whether a Betta fish poop? The answer is Yes! Betta fish do poop but they become picky when choosing the place to pee and poop.  Betta poops can be mistaken for uneaten fish pellet, because they tend to appear clumpy and round, unlike the poop appearance of other fishes that are stringy and long.

Betta will generally poop in the same place, and that is why you will see the waste located in one location. This may not be so when other tank mates are disturbing the bottom of the aquarium or when there is turbulence or strong current inside the tank.

Betta will normally poop near the plant area because they like to maintain privacy when doing so. Due to their private nature, it can be easier to clean their waste materials in the tank.

Betta fish have a stomach that is as big as their eyes, it is recommended that they get fed with 2-4 pellets one or two times a day. You can help the Betta improve its digestive health by not feeding it once in a week.

How do Fish Poop

How do Fishes process Poop and Pee

Just like humans, fishes do possess kidneys that help their bodies to produce urine. The shape and sizes of kidneys will normally depend on the fish species. The eels, for instance, have longer kidneys, while others are shorter, like those found in Angelfish species.

It can take several days for the processing of food in the intestinal tract of fishes, and that explains a delay in popping and peeing. Fishes must have a substantial amount of fiber in their meals to speed up metabolism.

Fish Poop and Pee and Their Health

The type of pee and poop coming out of a fish can indicate some health issues. Stringy poop, for instance, maybe an indication of parasitic or bacterial infection. In this case, the affected fish must be isolated in a separate tank and treated immediately.

Physical examination is not enough to ensure that your fish has a healthy digestive system that will aid in regular pooping. Veterinary examination of the digestive tract will help a lot to determine the health status of the animal.

Can a Fish Suffer Constipation?

Do you often wonder if a fish can suffer from constipation and other problems associated with over-feeding?

The appearance of a stringy poop that stuck to the body of the fish might be an indication that the fish is suffering from constipation.

You can help a constipated fish in a number of ways, especially if it is not pooping but has a bloated stomach. You should follow instructions when feeding pellets to the fish. Try as much as possible to avoid flake foods that can increase the susceptibility of the fish to constipation.

Prolonged over-feeding will eventually cause the expansion of the digestive tract of the fish, which can lead to a press on the swim bladder- this will eventually lead to issues with swimming.

Dealing with Irregular Pooping and Peeing in Fish

Maintaining regular pooping and peeing time in a fish starts with maintaining optimal metabolism. You can help the fish maintain a healthy metabolism by increasing favorable eating conditions in the tank.

It is important that you keep water temperatures at between 76 and 81F degree, colder temperatures are known to slow down metabolism in fish.

It is important that you help your fish to fast for a whole day, every week. This has a number of health benefits, especially with the improved digestion. It can also help in treating constipation in over-fed fish.

Improve flaring in the fish tank by placing a mirror near the tank. Some fish species are known to poop when flaring is encouraged. You may want to add a second compatible fish into the tank instead of placing a mirror near the tank; in this case, you may have to increase tank size.

If fasting does not help a constipated fish, you may want to replace the flakes with a pea diet. You should place the pea inside hot water for about 2 minutes, then transfer the pea into cold water until it becomes cool.

You should feed the fish with half of the thawed frozen pea a day if the fish is not pooping. It is believed that pea feed will help the fish to poop within 24 hours.

Increasing the fiber content of the fish is one of the best possible ways to improve pooping. Increasing moisture of fish food is also important but some brand does not contain a sufficient amount of fiber and moisture.

You need to check the flaky and freeze-dried fish foods for proper fiber contents before buying them for your fish. You may want to feed your fish with peas every 7-10 days to improve the digestive health of the fish.

Cleaning Fish Poop

Tips on Removing Fish Poop from the Tank

It is important to remove fish poop from a fish tank in order to avoid such materials from causing harm to the fish. Fish poop will contain colonies of bacteria, parasite, and fungi that can mix with new feed and ingest into the fish body.

The fish body will automatically become a living host for such parasites, thus causing serious health problems that can lead to the death of the fish.

Fish poop will normally settle on the floor of the tank until it is removed. Fish poop may also settle on the surface of aquarium plants. You should consider adding a filter to reduce the volume of waste inside the tank but do not use too many filters to avoid killing fish fry.

First of all, you must turn off any electrical component in the fish tank, especially the filter and heater. You should also shut down the air pump.

Make use of the algae scraper to clean the side of the fish tank. Some of the fish poop may be trapped on the algae.

Your next step is to remove between 40 and 50% of the water in the tank with the aid of a gravel vacuum that will pull the water into a bucket.

You can also make use of the vacuum to suck up as much debris as possible from the fish tank. The debris includes fish poop and leftover fish foods.

You may want to clean the decorations and equipment, especially those that have collected some of the fish poop or leftover foods.

You may not eliminate all the poop at once but subsequent changes in tank water will eventually help in removing poop remnants. Remember, you need to replace 15% of fish tank water on a daily basis, but for the weekly cleaning and removal of fish poop, you need to replace up to 50% of the tank water.

You must also keep in mind that the replacement tap water must be prepared before adding it to the tank. Tap water contains Chlorine and chloramine that can harm the fish. You can prepare your water either by boiling for about 2 hours or leaving it to stand overnight (for about 24 hours).

Make sure the freshwater is added slowly while the fish has been separated into a fish bag. Once the replacement of water is completed, simply pour some of the new water into the fish bag and let the fish sit in for about 20 minutes before pouring the water in the bag alongside the fish into the tank.

You can turn everything back on when the water replacement has been completed. Keep in mind that the removal of fish poop from the fish tank should be a weekly process. Do not ignore the cleaning of the external part of the tank once the inside has been cleaned.

Make use of a clean damp cloth to wipe the outside and avoid leaving a watermark there. Most tank owners often ignore the need to clean the outside of the tank when there are high possibilities of transferring germs from the outside into the fish tank. Make sure the external part of the tank stays dry always.
