What aquarium fish eat poop? Is there any fish that are habituated to eating the fish poop? That will be really nice since cleaning & maintenance requirements would have been much lower.
There are some bottom dweller fish and invertebrates such as plecos, catfish, sucker fish, shrimps, etc. which are known as poop eaters. However, they don’t eat fish poop, they often mistreat poop as their food. Accidentally, they may eat fish poop, but they don’t do that deliberately.
So, what aquarium fish you can add to help manage the fish poop in your aquarium? Are there any other ways? Let’s find out how you should manage the fish poop in your aquarium.
What fish will Eat Poop & clean the bottom of my tank?
Many aquarium fish are being used as the clean-up crew by fishkeepers. They clean the bottom of the tank by eating all the leftover foods, algae, and detritus. However, they don’t clean the fish poop. Instead, adding them to the tank will lead to more fish poop in the tank.
People often ask, do shrimp eat fish poop? If it’s not, what about snails? Do snails eat fish poop?
So, apart from fish are there any aquatic critters that clean the fish poop? The answer is NO. Shrimp and snails also don’t eat fish poop?
So, what’s the point of adding those bottom-feeder fish? Definitely, there are some valid reasons.
Bottom dweller fish help in many ways but not in poop management. They ingest foods that sink to the bottom, consume dead plant matter, and clean algae spores so that your tank remains pristine.
However, they can’t help you remove other fish poop, Instead, they will add more poop to your aquarium.
Still, you can add some of them to your tank, because of their other benefits. My favorite bottom feeder is cory catfish, they are beautiful, have different varieties, and most importantly keep my tank clean.

Why do You need To Remove The Fish Poop From Your Tank?
What happens if you keep the fish poop unattended in your tank? Fish waste builds up quickly especially if you don’t have a strong enough filter to handle that.
Fish waste including poop, urine, and discarded scale all contribute to ammonia spikes if your biological filter can’t manage that. Ammonia is toxic and detrimental to fish health. Moreover, ammonia is the single biggest cause of fish death in aquariums.
Therefore, you should implement proper measures to get rid of the fish poop so that it can’t hurt your fish.
How do I get rid of fish poop in my tank?
The idea of deploying some poop-eating fish is not feasible since no aquarium fish eats poop. So what are the effective ways to get rid of fish poop in your aquarium?
Using an aquarium gravel vacuum is the most effective & practiced way to get rid of the fish poop. However, there are some other alternatives. One way is to direct the flow towards filter intake by a powerhead and use a sponge at the intake to catch the poop. Other ways are to use a shovel and net to capture fish poop manually or install a fish poop filter.
Let’s move into the details of each method.
Use An Effective Filter & Powerhead to Direct the Flow
Effective and sufficient enough aquarium filter you should consider first for poop removal. The filter circulates water in the fish tank. Garbage present in the water gets trapped inside filter media. However, still in some areas where the water movement is low fish poop can pile up.
So, one of the ways is to use a sponge in the filter intake and increase the rate of water flow of the filter. However, keep in mind this method is only applicable if the fish you’re having can tolerate a strong current. Not all aquarium fish such as betta can’t adjust to the strong water flow.
If you own a big aquarium a powerhead or wavemaker is a good way to move water. With a powerhead, you can direct the flow in a specific direction, for example towards the filter intake.
Powerheads are not generally suitable for smaller aquariums since they generate a very powerful current. You can use small water pumps for smaller aquariums.
The whole concept is to direct the flow towards the filter intake so that fish poop can’t sink to the bottom. In addition, if the water movement is strong, it may stir out some of the fish poop already present in the substrate.
Utilizing a sponge in the intake will help you catch and remove the fish poop easily from the aquarium. Simply removing the sponge and washing it in clean water will help get rid of the fish poop.
Buy A Gravel Vaccum
The most effective way to remove the fish poop is to use a gravel vacuum. Vacuuming the gravel every few days will keep the substrate clear of fish poop.
This is the alternative to the first method. Having some maintenance accessories such as a gravel vacuum is quite handy for managing a fish tank.
Gravel vacuum stirs the top layer of substrates. Therefore, lighter debris including fish poop that is stuck inside gravel or sand gets sucked up along with water.
There are many types of gravel vacuum with varying prices. I have an article where I have listed the top & cheapest gravel vacuum for aquarium use. I encourage you to read that article.
Use A Shovel & Net
If you don’t have the budget or owner of a nano aquarium, you can use a shovel & net to clear the fish poop from the tank. It’s more of a manual approach & takes a bit more time.
Use the shovel to gently stir the substrate or scoop some of the fish poop visible on the substrate. For finer poop particles, use the net to catch those.
To keep the tank clear of fish poop you can use this method daily. However, if you have a sparingly stocked aquarium clearing the poop weekly is sufficient.
Install A Fish Poop Filter
A filter specially designed to catch fish poop is also a good alternative. This is a type of internal aquarium filter operates by an air pump and creates sufficient suction to flow water through the filter.
Fish poop collects in the bottom chamber of the filter, after that water passes through a biological cartridge that holds 100 quartz beads and houses beneficial bacteria. Bacteria then break down the fish poop.
