Are those tiny, fast-moving creatures darting around your shrimp tank driving you crazy? You’re not alone! As a shrimp keeper for over 10 years, I’ve battled these pesky scuds more times than I can count. Let me share everything I’ve learned about getting rid of scuds safely without harming your precious shrimp.
Quick Answer: The safest and most effective way to remove scuds from a shrimp tank is through manual removal using traps and careful netting. While it takes patience, this method won’t harm your shrimp like chemical treatments might.
What Are Scuds and Why Are They a Problem?
Scuds (Gammarus shrimp) are small crustaceans that often hitchhike into our tanks on plants or decorations. While they might look harmless, these little guys can cause big problems:
- Compete with shrimp for food
- Attack and eat baby shrimp
- Destroy delicate plants, especially moss
- Reproduce incredibly quickly
- Create excess waste in your tank
Signs You Have a Scud Problem
Here’s how to tell if scuds are taking over your tank:
- Fast-moving creatures darting around (much quicker than shrimp)
- Missing or damaged plants, particularly moss
- Fewer baby shrimp surviving
- Tiny transparent or brownish creatures gathering around food
- Lots of movement in the substrate when disturbed
Safe Methods to Remove Scuds from Your Shrimp Tank
1. Manual Removal with Traps
This is my go-to method! Here’s what you’ll need
- Planaria/scud trap
- Bait (I use blanched zucchini or carrots)
- Small net
- Container for collected scuds
Steps:
- Place trap with bait in tank before lights out
- Wait 6-8 hours (scuds are more active at night)
- Carefully remove trap and dispose of caught scuds
- Repeat daily until population decreases
2. The Turkey Baster Method
Super simple but effective
- Use a clean turkey baster
- Target scuds when they gather around food
- Quick suction to catch them
- Empty into a separate container
3. Baiting and Netting
My favorite DIY approach
- Boil a carrot slice until soft
- Attach to fishing line or plant weight
- Place in tank overnight
- Remove slowly in morning with attached scuds
- Repeat process several times
What NOT to Do
❌ Don’t use chemicals or medications
❌ Avoid adding predator fish (they’ll eat your shrimp too!)
❌ Skip the copper treatments
❌ Don’t completely tear down your tank
Prevention Tips
Once you’ve got the scuds under control, here’s how to keep them away:
- Quarantine new plants for 2 weeks
- Dip plants in diluted bleach solution (1:20 ratio)
- Regularly inspect tank for early signs
- Maintain regular cleaning schedule
- Don’t overfeed your shrimp
Long-term Management Strategy
I’ve found this weekly routine works best:
- Monday: Check and empty traps
- Wednesday: Quick substrate vacuum
- Friday: Plant inspection and maintenance
- Sunday: Water parameter check
My Personal Experience
Last year, I had a massive scud outbreak in my Crystal Red shrimp tank. It took me about 3 weeks of consistent trapping and manual removal, but I finally got them under control. The key was persistence – don’t give up if you don’t see results immediately!
Final Thoughts
Getting rid of scuds takes time and patience, but it’s totally doable without risking your shrimp’s health. Stick with manual removal methods and stay consistent with your approach. Remember, it’s better to work slowly and safely than to rush and potentially harm your shrimp colony.
Quick Reference Table: Scud Removal Methods

|---|---|---|---|
| Traps | High | None | Medium |
| Manual Removal | High | None | High |
| Bait & Net | Medium | Low | Medium |
| Turkey Baster | Medium | None | High |

FAQ
Are scuds bad for a shrimp tank?
Considering the fact that scuds are extremely voracious scavengers, in small aquariums, they will outcompete shrimp easily. Another problem is that baby shrimp will suffer the most in this situation. The point is that when shrimplets are small they prefer to stay for several days in one place where they can hide.
How to treat ick in a shrimp tank?
There are numerous techniques for treating ich, from gentle herbal solutions to very invasive ones, but after years of testing, Aquarium Solutions Ich-X is our medication of choice. It’s very effective and safe to use with any fish (even scaleless ones), shrimp, snails, and live plants.
How do I get rid of copepods in my shrimp tank?
While performing a water change, use your finger to stir up the substrate and kick up the underlying detritus as you siphon. Tip: Copepods are attracted to light – shine a flashlight in one area of the tank to gather a cluster of them together, then they can be easily removed from the tank via siphon.
How do I get rid of parasites in my shrimp tank?
Mix a tablespoon of non iodized salt with 1.5 cups of tank water. Net the shrimp and put it into the salt solution. The parasite should drop off the shrimp pretty quickly. Once it drops off put the shrimp back in the tank.
