Frequently Asked Questions (FAQs)

1. Can you feed spirulina to fish?

Spirulina is good for fish for many of the same reasons it is good for humans. It offers full proteins even though it comes from a plant—one of the few plants to do so. It can also boost fish immune systems to fight off diseases and bacteria before they start problems with your fish.

2. Is spirulina good for aquarium plants?

Spirulina will enhance the production of special enzymes that break down digested fats into energy rather than letting them build up in the fishes body. It has been proven that spirulina will bring out the coloration of your fish better; this is due to the carotene pigments that are found in the algae.
