As an aquarium enthusiast, I’ve often heard people say shrimp are like the janitors of fish tanks But do these little guys actually eat fish poop? Let’s dive into the facts and bust some common myths about shrimp and aquarium waste management.
The Quick Answer

- Algae
- Uneaten fish food
- Dead plant matter
- Biofilm

What Shrimp Will Clean:
- Leftover fish food on substrate

- Biofilm on decorations and glass
- General detritus (except poop)
What Shrimp Won’t Clean:
- Fish waste/poop

Common Misconceptions About Clean-up Crews
Let me clear up some stuff I keep hearing in the hobby:
❌ “Shrimp eat everything including poop”
✅ Shrimp are selective eaters and avoid waste
❌ “Adding more clean-up crew fixes waste problems”
✅ Proper maintenance is the real solution
❌ “Clean-up crews eliminate the need for water changes”
✅ Regular maintenance is still necessary
Taking Care of Your Clean-up Crew
Even though they’re cleaners, shrimp need proper care too:
Feeding Requirements:
- Algae wafers
- High-quality shrimp pellets
- Blanched vegetables
- Supplemental foods
Optimal Conditions:
- Temperature: 65-80°F
- pH: 6.5-7.5
- Clean water
- Hiding spots
- Plant coverage
The Bottom Line
Look, I’ve been in this hobby long enough to know there’s no magical creature that’ll eat fish poop. While shrimp are awesome tank cleaners, they’re not waste processors. The best approach is:
- Maintain regular cleaning schedule
- Use proper filtration
- Don’t overstock or overfeed
- Keep shrimp as part of a balanced clean-up crew
Remember, a healthy tank needs both good maintenance and a diverse clean-up crew. Shrimp are just one piece of the puzzle!
Pro Tips from My Experience
Here’s what I’ve learned from keeping shrimp in my tanks:
- Start with a small group (5-10 shrimp)
- Make sure your tank is well-established
- Provide plenty of hiding places
- Don’t rely solely on them for cleaning
- Feed them properly despite their cleaning duties
Final Thoughts
While shrimp won’t eat fish poop, they’re still valuable members of any aquarium community. They help maintain tank cleanliness in their own special way, just not by eating waste. Keep realistic expectations, maintain your tank properly, and enjoy these fascinating little creatures for what they actually do!
Remember: A clean tank is a team effort between you, your filtration system, and your clean-up crew. Don’t expect any single component to do all the work!
Introduction To Poop-Eating Fish
Freshwater aquariums are dirty. There are dozens, if not hundreds, of different organisms and microbes that work together to make these contained ecosystems operate. Believe it or not, fish poop is essential for making these systems run efficiently and safely.
But what happens if you have too much fish poop entering the system? This can be due to overstocking, poor maintenance, inadequate filtration, or overfeeding.
Overloading The Nitrogen Cycle
As with anything, too much fish poop can overload the system with nutrients. When first starting a fish tank, ammonia must be added to the aquarium to initiate the nitrogen cycle. Over time, different microorganisms convert this ammonia into nitrite and, eventually, nitrate. This population of beneficial bacteria directly correlates to the amount of fish waste available and the subsequent levels of ammonia produced in the aquarium.
Simply put, more fish waste equals more ammonia and bacteria.
However, beneficial bacteria need to reproduce in order to compensate for higher ammonia levels, which takes time. A sudden or large raise in the level of ammonia in the system can leave toxic chemicals in the water column. This directly exposes fish, invertebrates, and live plants to potential ammonia poisoning, which can quickly become lethal.
The only way to prevent ammonia from overwhelming the nitrogen cycle is by removing fish poop and other wastes in the aquarium before they have the chance to break down.
