Frequently Asked Questions (FAQs)

1. Can I feed my fish Daphnia?

Yes. Daphnia is similar to what a Betta fish would eat if they lived in the wild, so it's great for your fish. You can buy daphnia in three forms: frozen, freeze-dried or live.

2. What is the best food for Daphnia?

Feeding. Daphnia are filter feeders. They strain microscopic food particles from the water. Daphnia pellets, an algae food source, and a baker's or brewer's yeast suspension are all good feeding options for cultures.

3. Can I feed my fish Daphnia everyday?

We recommend no more than 1.8 grams of Daphnia a day. There will be days your Betta may want less, so make sure to remove any uneaten frozen or freeze-dried food. How often can I feed Daphnia to my Betta fish? We would suggest offering Daphnia to your Betta pet in two feeding sessions.
