Reefalicious Live Rotifers

• Sized for larvae and fry – rotifers are smaller than copepods, which matters in the first days after fish larvae hatch, before their mouths are big enough for larger live food.
• High in protein and fatty acids, per Reefalicious, supporting early growth and survival rates in larval-rearing setups.
• Also useful for adult filter feeders – corals and other filter feeders will take rotifers alongside phytoplankton and copepods.
• Short shelf life once delivered – use within about three days of arrival, so this is a buy-when-you-need-it product rather than one to stockpile.

All four are sold in 250 mL and 500 mL bottles and are stored and shipped the same way – refrigerated, and used promptly after arrival.

Shake the bottle gently before use. For larval rearing, target-feed a small amount directly into the rearing vessel or the area where fry are concentrated, several times a day if you're actively raising larvae. For general tank use, dose into the display or sump as a supplementary live food alongside phytoplankton and copepods.

Suitable for: larval and fry rearing setups; reef tanks wanting an additional live food source for filter feeders.

Not suitable for: long-term storage – use the bottle within a few days of arrival rather than keeping it as a standing supply.

Refrigerate on arrival and use within about three days. Rotifer cultures decline quickly once bottled, so this is best bought close to when you need it rather than kept on hand.

• Reefalicious Live Phytoplankton – the standard food for a rotifer culture, and useful to dose alongside rotifers to keep them fed in a rearing tank.
• Reefalicious Live Copepods – a next-size-up live food as fry grow past the point where rotifers are big enough.

As a live product with a short usable window, arrival condition and timing matter – get in touch straight away if a bottle arrives in poor condition. Otherwise the usual consumer guarantees under Australian Consumer Law apply.

Why only a three-day window?

Rotifer cultures are fragile once bottled and decline in condition faster than the other Reefalicious live foods – buy close to when you plan to use it rather than stockpiling.

Are rotifers necessary, or can I go straight to copepods?

For newly hatched larval fish, rotifers are usually necessary – many species' mouths are too small for copepods in the first days after hatching. Once fry grow, copepods become the better ongoing food.

Can adult fish and corals eat rotifers too?

Yes – rotifers work as a general live food for filter feeders and small fish alongside phytoplankton and copepods, not just as a larval-rearing food.

What's the difference between the 250 mL and 500 mL bottle?

Only the volume of live culture. Given the short usable window, buy the size you'll actually use within a few days rather than defaulting to the larger bottle.
