SFBB Spirulina Brine Shrimp Cube 3.5oz

San Francisco Bay Brand Spirulina Brine Shrimp are whole adult brine shrimp (Artemia spp.) gut-loaded with spirulina algae and flash-frozen to lock in nutrition and color. The added spirulina delivers plant matter, carotenoids, and vitamins that promote health and enhance the natural coloration of both freshwater and saltwater fish. It is an excellent everyday treat for community tanks and reef aquariums, and especially valuable for omnivores and grazers that benefit from vegetable content. Each 3.5 oz box holds 30 pre-portioned cubes. Browse more of our frozen and prepared fish foods.

Why Spirulina Brine Shrimp

• Color and health boost. Spirulina is rich in natural pigments and vitamins that enhance color and support a strong immune system.
• Adds plant matter. The vegetable content suits omnivores and grazers such as tangs, mollies, and many cichlids that need more than pure protein.
• Fresh and saltwater favorite. Readily accepted by community fish, livebearers, tangs, angelfish, and reef inhabitants alike.
• Pre-portioned cubes. Thirty individual cubes per box let you feed exactly what your tank needs with no thawing waste.

How to Feed

1. Pop out one cube and thaw it in a small cup of tank water. Never microwave or refreeze.
2. Feed as a treat 2 to 3 times per week alongside a staple flake or pellet.
3. Offer only what your fish finish in a couple of minutes, then net out anything uneaten.
4. Return the box to the freezer right away to keep the remaining cubes solid.

Frequently Asked Questions

What does the spirulina do?
Spirulina is a nutrient-dense algae rich in pigments and vitamins. Gut-loading the brine shrimp with it adds plant matter that enhances color and supports immune health, making it more complete than plain brine shrimp.

Can I feed this to both freshwater and saltwater fish?
Yes. The box is formulated for all fresh and saltwater fish, so it works in community tanks, cichlid setups, and reef aquariums alike.

How often should I feed it?
Feed it as a treat 2 to 3 times a week alongside a balanced staple diet. It is a supplemental food, not a sole diet.

How do I get it home still frozen?
We keep it in our freezer until you pick up, and we recommend an insulated bag such as the SFBB Fish Food Icebox for the trip home. Do not refreeze once it has thawed.
