Hey shrimp lovers! I’ve been keeping shrimp for years, and one of the most common questions I get is whether shrimp actually need a filter. Let me break this down for you in a way that’ll make total sense, even if you’re just starting out.
Quick Answer While shrimp can survive without a filter in certain setups, most shrimp keepers (including myself) recommend using one for the best results and easiest maintenance.
Why Consider Using a Filter?
Here’s the deal – shrimp are super sensitive to ammonia and nitrite. Trust me I learned this the hard way when I first started! A good filter helps by
- Creating beneficial bacteria colonies that process waste
- Keeping water moving and oxygenated
- Collecting debris and waste
- Making maintenance easier
- Providing extra surfaces for biofilm (shrimp love this!)
Types of Filters That Work Great for Shrimp
1. Sponge Filters
These are my absolute favorite! Here’s why
- Super safe for baby shrimp
- No moving parts to worry about
- Affordable (usually under $20)
- Easy to maintain
- Great for biological filtration
2. Hang-on-Back (HOB) Filters
These work well if you:
- Want more powerful filtration
- Have a larger tank
- Like the waterfall effect
- Need extra space for filter media
Just make sure to cover the intake with a sponge to protect the shrimplets!
3. Matten Filters
These are like the heavyweight champions of shrimp filters:
- Massive surface area for bacteria
- Creates awesome feeding zones
- Perfect for breeding tanks
- Super stable filtration
Going Filterless: Is It Possible?
Yes, but it’s tricky! If you’re gonna try this, here’s what you need:
-
Lots of Plants – And I mean LOTS! Focus on:
- Floating plants
- Fast-growing species
- Dense planting
-
Walstad Method
This is basically a heavily planted tank that uses plants as natural filtration. It works, but:
- Takes months to stabilize
- Needs careful planning
- Requires plant knowledge
- Regular maintenance is crucial
My Personal Experience
I’ve tried both filtered and unfiltered setups. While my filtered tanks have always been more stable, I did manage to keep a small colony of Red Cherry Shrimp in a heavily planted 2-gallon bowl without a filter. But honestly? It was way more work than my filtered tanks.
Maintenance Tips
Whether you go filtered or filterless, here’s what ya gotta do:
For Filtered Tanks:
- Clean sponges every few months
- Use old tank water for cleaning (never tap water!)
- Monitor water flow
- Watch for debris buildup
For Filterless Tanks:
- More frequent water changes
- Regular plant trimming
- Careful feeding
- Constant monitoring
Bottom Line
While you can keep shrimp without a filter, I wouldn’t recommend it unless you’re super experienced or ready for extra work. A simple sponge filter costs like $15-20 and makes life so much easier!
Quick Setup Guide
For beginners, here’s what I recommend:
- Get a sponge filter
- Add an air pump
- Cover any intakes with fine sponge
- Cycle the tank properly
- Add plants
- Then add your shrimpies!
FAQs
Q: Will my shrimp die without a filter?
A: Not necessarily, but they’ll need perfect conditions and lots of plants.
Q: What’s the cheapest filter option?
A: Sponge filters! They’re cheap and super effective.
Q: How long should I run my filter before adding shrimp?
A: At least a few weeks to establish good bacteria colonies.
Remember, keeping shrimp isn’t rocket science, but giving them the best environment possible will make your life easier and their lives better! Trust me, I’ve learned these lessons through trial and error, and a good filter setup is worth every penny.

Lighting for shrimp tanks
Use a small LED light to enhance the shrimp colours. Many people combine shrimp with live plants, so if wanting to grow aquarium plants you’ll need a light that encourages plant growth. Set the light to come on for 8-10 hours per day.
Shrimp are best over natural substrates like inert sand, gravel or aquatic soil. With soil also being the best for aquatic plants. Slope the substrate front to back to enable root growth.
Decor can range from stones to wood, to botanicals like leaves, which the shrimp-like to graze on. Make sure its inert, or lime-free.
Plants can help the biology of an aquarium by taking up nutrients and producing oxygen. Shrimp also like to hide in them and graze them for algae and food particles. If you include live plants, fertilise them on a regular basis to keep them green, healthy and growing.
Heaters for shrimp aquariums
Cherry shrimp are fine at room temperature but for other shrimp, either choose a small, preset heater or a small, adjustable heater/thermostat. You’ll need one watt of heater per litre of water, so a 10 litre tank will only need a 10 watt heater. Use a thermometer to monitor temperature.
