What Are Live Rotifers?

Live Rotifers (Brachionus plicatilis) are very tiny animals measuring between 150-360 micrometers. Rotifers are often raised as food for live corals and fish larvae. They are the ideal starter food for species of fish such as clownfish fry which have tiny larvae with very, very tiny mouths.

What Does Enriching Mean?

Enriching means feeding a premium food that contains fatty acids (especially ARA, EPA and DHA), carbohydrates, proteins, and vitamins. 12-24 hours before our rotifers are dispatched we enrich them, this process is also known as “gut loading”. When our rotifers are enriched with the desired feed, this does not only fill the gut but the enrichment feed is gradually incorporated into the rotifer tissues.

Who Should Use Live Rotifers?

Almost any marine aquarium will benefit from the addition of rotifers, Their size and excellent nutritional value (50% to 65% protein) make them the perfect live food for all (freshwater and marine) fry, anemones, sponges etc.

How To Feed Live Rotifers?

To add them to your system, simply pour the bottle directly into the aquarium or use a sieve to strain them. Feed as little or as much as required. Rotifers can be stored in the fridge for up to 5 days. Rotifers are perfect for a reef's food source because they multiply very rapidly and they are just the right size for almost all filter feeders and clown fish fry.

Which Rotifers Do You Stock?

We stock (Brachionus plicatilis) which is the "L" strain which range in size from 150-360 microns. Our live rotifers are cultured in saltwater with a specific gravity of 1.019. and are usually maintained at a population density of 200 to 300 rotifers per ml of water.

Do I need a rotifer sieve?

We advise you strain your rotifers through a 54 micron sieve, for small quantities like 100ml or 250ml pouches you can pour the liquid straight into your tank.

Our rotifer culture may also contain copepod nauplii as we culture both copepods and rotifers together, however through a straining process we are able to separate the 2 up to 99%.

Do I Need Rotifer Enrichment?

Our rotifers are enriched before dispatch but if you intend to culture your own rotifers or you need to enrich further, then we recommend our rotifer enrichment feed. The body of a live rotifer has very little nutritional value - the stomach contents and eggs are where the nutritional value exist. Rotifers can be fed on a variety of small micron feeds and the resulting rotifer will have the nutritional profile of those feeds.

The last 6-12 hours of feeding are the most important for determining the value of the rotifer. There are several diets available for growing rotifers, but by far the best diet is marine microalgae. Marine microalgae contains the important nutritional elements needed for larval development including fatty acids (especially EPA and DHA), carbohydrates, proteins, amino acids, and sterols.

Microalgae produces almost no fouling in your system (unlike powders and emulsions) so it is much easier to maintain long term rotifers cultures.

Our Rotifer Enrichment product contains a high concentration of Nannochloropsis and Isochrysis phytoplankton.

Enrichment directions. If you wish to enrich your rotifers further then add 1 - 5 drops of our rotifer enrichment to your live rotifers 6-12 hours before feeding to your fry or corals.

Rotifer Culturing Instructions. 

1. Culture vessel:  This can be anything such as a 2 litre cola bottle to a 5 or 10 gallon aquarium.

2. Culture water: You will need some freshly mixed clean seawater, do not use water from an existing aquarium or culture as this will contaminate your attempt to start a new culture of rotifers. A specific gravity of 1.017 to 1.021 for this strain of rotifer is suggested.

3. Small air pump, and airline tubing (Do not use an airstone) this keeps the Rotifer Food in suspension.

4. Cover to keep dust and contaminants out and evaporation down.

5. A food source, such as our Super Concentrated Rotifer Feed.

Fill your container half to two-thirds full with the clean seawater. Attach the airline to the air pump. Put the end of the airline into culture vessel, and plug in the air pump. Make sure you use a drip loop and check valve to keep water from getting into your pump and electrical outlet.

Add a small amount of Reefphyto Rotifer Feed to lightly colour the culture water. Do not add too much, or the water will foul, the best way to describe the colour of the culture water should be is "cucumber flesh green". Add your new rotifer culture to the vessel, and you are done!
Over the next coming days, your rotifers will reproduce. It may seem at first that they aren't reproducing as fast as you would like, but once they get to a certain population level you will see an "explosion" of rotifers in your culture vessel.

Feed with Reefphyto rotifer feed as necessary to keep the water lightly tinted, and monitor water quality. Crashes from overfeeding that leads to high ammonia and nitrite are possible, water changes of 50% should be carried out every 4-5 days to maintain water quality .
To harvest your rotifers, use our fine mesh Rotifer Sieve and strain the required amount of rotifer culture over the sink or bucket. Replace the water you have strained with fresh seawater (not with the old strained water).

Make sure you do not dip your strainer in the rotifer culture, and then in your aquarium, and then back in your culture vessel without cleaning it first. Likewise, keep siphon tubing and other equipment you use on your culture separate from equipment you use in your aquariums or larval tanks to avoid contamination.

Over the period of a week there will be a build up of waste in the bottom and sides of your rotifer culture container which will need to be siphoned out to avoid your culture crashing. Its often easier to transfer your culture into a clean container every 4-5 days  keeping the culture clean and healthy.
