FAQ
Can I feed this product to my fish daily?
It is recommended to feed Spirulina Brine Shrimp a couple of days before stressful events, not on a daily basis. Daily feeding may not provide the intended immune support and could lead to overfeeding.
Is this product safe for all fish species?
This product is suitable for freshwater and saltwater species listed in the description. Always ensure compatibility with your specific fish species before introducing new food.
How should I store the frozen cubes after opening?
Keep the product frozen until ready to use. Thaw only as needed and feed immediately. Do not refreeze once thawed.

Nathan Robertson –
My cichlids started showing better color and activity after I started feeding them Spirulina Brine Shrimp before water changes. The cubes are easy to thaw and the fish seem to enjoy them.
Neil McLean –
Used this before moving my tank to a new room. My tangs stayed calm and active during the transition. The spirulina boost seems to help with stress recovery.
Jason Clarkson –
Great product for immune support. My platies were more energetic after a few days of feeding. The texture is good and the fish eat it readily.
Jane Fraser –
The cubes don’t dissolve easily in the tank. I had to break them up manually. Works well for a few days, but not ideal for long-term feeding.
