SIZE: 150 to 300um

MEDIUM: Shipped in a dense solution of phytoplankton called Phytopreme Live, comprised of Tetraselmis, Nannochloropsis, Isochrysis, Pavlova,Thalassiosira  weissflogii, Synechococcus .. (This is the food that we feed our Zooplankton cultures here at the nursery). 

FACTS: This rotifer strain is one of the most important live feed items in the food chain. It is used all over the world in production nurseries, fish and invertebrate farms and utilized for culturing and raising saltwater animals such as corals, vertebrate and invertebrate larvae of all kinds of species, fish and shrimp, crustaceans, etc.

BENEFITS: Using rotifers as live food for home aquariums will provide a very necessary link in the food chain in your miniature ecosystem at home that we call aquariums. This, in turn, will allow you to have a more balanced aquarium habitat because you will be introducing microfauna into your system.

We, as hobbyists, are starting to become aware of the difference between feeding dead food such as frozen or freeze dried, as opposed to feeding live organisms to our pets.

It is a lot more beneficial to introduce live organisms as food such as copepods or rotifers and live unicellular algae Phytoplankton, mysid shrimps etc., because they will stay alive and may even reproduce in your system if conditions are right.

Save time and money, order live saltwater rotifers in bulk or wholesale quantities.

Let us do the work of keeping high densities of live rotifers available on demand to ship to your door when you need it. Send an email with quantities and we will quote you for wholesale saltwater rotifer cultures.

USES: Our rotifers can be used to feed most types of corals, newly hatched fish fry and larvae, seahorse fry, copepods, and amphipods. You will notice an immediate reaction from your corals if they have never been fed live zooplankton in your aquarium. They will open up and stick out tentacles that they hardly ever revealed before. Their soft bodies will puff out to 3 to 4 times their size. It is just amazing to watch their reaction. After 3 to 4 weeks their colors will become more vibrant.

CULTURE: We grow our rotifers with 6 kinds of algae. We also feed them a solution called Roti-Food that contains omega 3 fatty acids, HUFA, Marine lipids, various vitamins (C, B12, etc) and trace elements. We use these rotifers in our own aquaculture development.

Best way to handle and keep live rotifers after you receive the culture.


Best is at room temp. Best way to keep alive after receiving is culture them  in 1.020 salinity and feed our Roti-Food feed twice daily or as needed. Just have to worry about water quality.


You can actually keep them alive indefinitely. With the food and oxygen in the ship bag they can stay alive for 7- 10 days at room temp. Once you open the bag then that all changes.


Guaranteed to arrive alive or we send you a new batch for free.

I think the quality of rotifers is excellent! My little Rainsford's goby has a good supply in my nano tank, and I'm working on building more in another tank. Thank you!
