With the Artemia Breeder, Artemia Nauplien can be easily bred with little effort The special construction of the breeder ensures gentle swirling of the artemia eggs and nauplii without them being deposited in dead corners At 24 °C, the nauplii hatch approximately after 24 - 36 hours, at 20 °C after 30 - 40 hours The egg separator reliably separates the empty egg sleeves from the nauplii Nauplii are removed with the feed pipette via the lid opening (aquarium air pump, e.g. the Bubble Air Pump 100 required)
