Yes, shrimp love munching on diatoms! As someone who’s kept aquariums for years, I’ve watched these fascinating creatures graze on these tiny single-celled algae. Let me break down everything we know about this microscopic feast.
Quick Answer
Most shrimp species eat diatoms, especially when they’re young. These microscopic algae are like nature’s multivitamins for shrimp, packed with essential nutrients they need to grow and thrive.
What Are Diatoms Anyway?
Before we dive deeper, let’s get something straight – diatoms are these super tiny algae covered in glass-like shells made of silica. They’re basically like microscopic snacks floating around in the water!
Why Do Shrimp Love Diatoms So Much?
Nutritional Powerhouse
Diatoms are like little nutritional goldmines for shrimp. Here’s what they pack:
- Essential fatty acids (for healthy cell membranes)
- Proteins (building blocks for growth)
- Vitamins (keeps their metabolism running)
- Minerals (helps build strong shells)
Different Shrimp, Different Appetites
Not all shrimp are crazy about diatoms in the same way. Here’s how different shrimp species approach their diatom dinner:
- Glass shrimp (Palaemonetes): Absolute diatom lovers
- Brine shrimp (Artemia): Can’t get enough of them
- Freshwater shrimp (Caridina & Neocaridina): Regular grazers
How Do Shrimp Actually Eat These Tiny Things?
We’ve spotted shrimp using three main methods to chow down on diatoms:
- Filter Feeding: Some shrimp are like living water filters, straining out diatoms from the water
- Grazing: Others prefer the “buffet style” – scraping diatoms off surfaces
- Detritus Feeding: Some get their diatoms second-hand through eating decaying matter

How to Tell If Your Shrimp Are Eating Diatoms
Watch for these signs
- Shrimp actively grazing on tank surfaces
- Less visible brown algae on glass and decorations
- Healthy, colorful shrimp (diatoms help with pigmentation!)
Growing Diatoms for Your Shrimp
Wanna cultivate some diatom snacks? Here’s what you need:
- Good lighting
- Proper silicate levels
- Balanced nutrients
- Clean water conditions
Common Questions We Get Asked
Are Diatoms Bad for Shrimp?
Nope! They’re actually super healthy Just make sure your tank water is clean – polluted water can make diatoms store nasty stuff
Do Adult Shrimp Need Diatoms?
While adults aren’t as dependent on diatoms as babies, they’ll still munch on them when available. It’s like how we still enjoy snacks even though we don’t need them as much as growing kids do!
What About Baby Shrimp?
Baby shrimp LOVE diatoms! They’re perfect first foods for the tiny ones – easy to digest and packed with everything they need to grow.
Pro Tips from Our Experience
- Don’t panic about brown algae in new tanks – your shrimp will probably love it
- Balance is key – too many diatoms can make your tank look messy
- Consider diatoms as part of your shrimp’s varied diet
- Watch your shrimp’s behavior – they’ll show you if they’re getting enough to eat
Why This Matters
Understanding the relationship between shrimp and diatoms isn’t just cool tank-keeper knowledge – it’s crucial for:
- Maintaining healthy aquariums
- Breeding successful shrimp colonies
- Creating balanced ecosystems
The Bottom Line
Diatoms are like nature’s perfect shrimp food – especially for the little ones. While you don’t need to stress about maintaining a perfect diatom garden, knowing they’re part of your shrimp’s natural diet helps you create a better environment for your aquatic friends.
Remember, every tank is different, and what works in one might not work in another. Keep watching your shrimp, and they’ll let you know if they’re happy with their microscopic meals!

What Causes Brown Algae (Diatoms)?
Diatoms are usually the first type of “algae” that we see in our aquariums. They usually begin to appear shortly after the tank is set up because the aquarium is still cycling. Because the tank isnt balanced and the water quality/water parameters may be fluctuating, the diatoms use this to their advantage. Similar to plants, diatoms feed on nitrates and phosphates.
Nitrates are a by-product of the nitrogen cycle, in which fish waste and other decaying plant matter release ammonia and phosphates. Beneficial bacteria in the aquariums filter media will convert the ammonia into nitrites, and then finally nitrates. If there are not enough plants in the aquarium and nitrogen levels are high, diatoms will begin to thrive. The brown algae is highly likely to flourish and spread across the surfaces of the tank, substrate, and decorations under these circumstances.
These diatoms are sometimes referred to as “silica algae”. This is because they utilize the silica in their surroundings to strengthen their cell walls. High amounts of silica in the water may be a primary cause of brown algae. Silica is often found in tap water and water from wells.
- Note: Dont be discouraged if you see brown algae, its quite common amongst new tanks! As the tank matures and maintenance is kept up, diatom growth will decline.
How Do I Remove Brown Algae from My Aquarium?
Luckily, brown algae is pretty easy to remove from the tank. It doesn’t stay glued onto surfaces like Black Beard Algae or Blue-Green Algae. If you find Diatoms on the surface of the aquarium glass, they can easily be scraped off with an extended scraper or even an old gift card. For those that want to regularly clean the glass without getting their hands wet, there are magnetic scrapers available that make cleaning more convenient.
If the diatoms are coating the plant leaves, gently rub/brush them off with your fingers or a toothbrush. Whenever they are on tougher surfaces like rocks and stones, use a toothbrush or wire brush to scrub them off. Once you’ve polished off as much of the brown algae as possible, make sure to remove the algae and leftover debris from the tank by using a gravel vacuum or some other form of a siphon.
