Hey fellow fish keepers! I’ve been in the aquarium hobby for years and one thing I’ve learned is that frozen brine shrimp can be a game-changer for your fish’s health and happiness. Today, I’m gonna share everything you need to know about feeding these nutritious little crustaceans to your aquatic pets.
Why Frozen Brine Shrimp is Amazing for Your Fish
Before we dive into the how-to, let me tell you why frozen brine shrimp is such a fantastic food choice:
- Natural Fiber Source: The tough exoskeleton acts like fiber, helping your fish digest food better
- Protein-Rich: Perfect for growing fish and breeding conditions
- Easy to Digest: Great for picky eaters or sick fish with low appetite
- Nutrient Dense: Packed with healthy fats and proteins, especially when gut-loaded
- Versatile: Suitable for most fish species, from tiny tetras to larger cichlids
Different Types of Frozen Brine Shrimp
We’ve got two main types to choose from:
-
Regular Adult Brine Shrimp
- Larger size (around 0.4 inches)
- Perfect for medium to large fish
- Great for community tanks
-
Baby Brine Shrimp
- Tiny size (about 450 microns)
- Ideal for fry and nano fish
- Contains extra yolk sacs full of nutrients
How to Feed Frozen Brine Shrimp: Step-by-Step Guide
Method 1: Direct Feeding
- Take the frozen cube out of the freezer
- Drop it directly into the tank
- Watch as it thaws and your fish start feasting
Pro tip: This method works best if you’ve got lots of active fish who aren’t shy about eating!
Method 2: The Thaw-and-Feed Method (My Favorite!)
- Get a small container ready
- Add some tank water to it
- Put the frozen cube in
- Wait 3-5 minutes for it to thaw
- Use a turkey baster or pipette to target feed your fish
Pro tip: I like this method best cuz it gives me more control over feeding portions and helps prevent waste.
Method 3: The Worm Feeder Cone Technique
- Place the frozen cube in a worm feeder cone
- Hang it in your tank
- Let it slowly release as it thaws
This method’s great for
- Preventing stronger fish from hogging all the food
- Making feeding time last longer
- Keeping your tank cleaner
Important Do’s and Don’ts
Do’s:
- ✅ Feed appropriate portions for your fish population
- ✅ Remove any uneaten food after 30 minutes
- ✅ Store frozen food properly in your freezer
- ✅ Mix up your fish’s diet with other foods
Don’ts:
- ❌ Leave frozen food at room temperature for more than 30 mins
- ❌ Refreeze thawed food
- ❌ Overfeed your fish
- ❌ Feed only frozen foods exclusively
Feeding Schedule and Portions
Here’s a rough guide to get you started:
| Tank Size | Cube Size | Feeding Frequency |
|---|---|---|
| 10 gallons | 1/4 cube | 2-3 times/week |
| 20 gallons | 1/2 cube | 2-3 times/week |
| 30+ gallons | 1 cube | 2-3 times/week |
Tips for Picky Eaters
Sometimes fish can get a bit fussy about their food. Here’s what’s worked for me:
- Mix and Match: Combine frozen brine shrimp with their regular food
- Target Feeding: Use a pipette to place food right in front of shy fish
- Timing Matters: Feed at the same time each day
- Be Patient: Sometimes it takes a few tries for fish to accept new foods
Common Problems and Solutions
Problem 1: Fish Ignore the Food
Solution: Try thawing it first and using a turkey baster to create more movement in the water
Problem 2: Water Gets Cloudy
Solution: Use the thaw method and remove uneaten portions after feeding
Problem 3: Stronger Fish Eat Everything
Solution: Use a worm feeder cone or target feed with a pipette
Making the Most of Your Frozen Brine Shrimp
To get extra nutritional value, try these tricks:
- Add vitamin supplements during thawing
- Mix with spirulina for color enhancement
- Combine with other frozen foods for variety
- Use gut-loaded brine shrimp when available
The Bottom Line
Feeding frozen brine shrimp isn’t rocket science, but doing it right can make a huge difference in your fish’s health and happiness. Remember to start small, observe your fish’s response, and adjust accordingly.
And hey, don’t forget to have fun with it! Watching your fish go crazy for brine shrimp is one of the most rewarding parts of the hobby. Trust me, once you get the hang of it, you’ll wonder why you didn’t start sooner!

Frozen fish and coral foods should be defrosted before being added to your aquarium. Any small container like a disposable cup or small Tupperware works well. AquaMaxx makes a dedicated frozen food strainer that works out nicely if you want to remove the liquid and just feed the food directly without a squirt feeder or bulb syringe.
There are also in-tank defrosters like those from Innovative Marine and eShopps which actually allow you to just drop the frozen chunk of food directly in your tank. The defroster isolates the food from your fish while its frozen and slowly distributes the food as it thaws out through the bottom.
- With a thawing cup add the amount of frozen food you wish to feed your aquarium for a single feeding.
- Add approximately 4 Tbsp of RO/DI water per cube of food to the thawing cup. Tank water will work as well.
- Add any food soaks you wish to use like Selcon, amino acids, or vitamins to the cup. Let it soak for 10-20 minutes or as directed by the food soak.
- Occasionally stir the cup until the food is completely defrosted.
- You can strain and dispose of any residual liquid from the food or you can also just feed the liquid food mix directly.
- Turn off your aquariums filtration pumps, and any excessive water flow.
- Using your favorite feeding tool or bulb syringe, you can target feed your fish and corals or just pour the food into your aquarium directly.
- Feed only what they can consume within 2-3 minutes at one time. Let the fish eat everything before adding any more.
- Leftover food can be stored in the refrigerator for feeding later but its probably not a good idea to keep the thawed food for any longer than 24-48 hours.

FAQ
How do you feed brine shrimp?
Feeding. Brine shrimp are filter feeders and remove fine organic particles from the water as they swim. Unicellular algae, such as Spirulina, and bacteria are natural food sources. Powdered Spirulina flakes or powder fish food flakes can be purchased from a pet store and scattered on the water’s surface.
Can I feed my fish frozen brine shrimp every day?
For typical omnivores or community fish, you can feed frozen foods anywhere from once a week to several times a week. For pufferfish, African dwarf frogs, and other picky eaters, they may refuse to eat anything except for live or frozen foods.
How often can I feed my betta frozen brine shrimp?
Frozen bloodworms and baby brine shrimp are great supplements but should not be the main diet. You can feed them about 2–3 times per week, alternating between the two if you’d like. Overfeeding rich foods like bloodworms can cause bloating or water quality issues, especially in smaller tanks.
