La cuve de lifestyle doit être remplie avec ten L d’eau de tradition à 1025 de salinité. Il est toujours attainable de cultiver les rotifères avec une eau in addition faible en salinité, mais pour le récifal il est interessant d’avoir une eau proche des paramètres de l’aquarium afin de favoriser les odds de survie lors du transfert.
Ajouter du phytoplancton vivant afin de colorer l’eau ( vert clair ). Nous conseillons idéalement le phytoplancton marin Nannochloropsis Salina très riche en acide gras et source d’EPA et/ou le phytoplancton Tetraselmis sueccica.

Lots of species are parthenogenic rotifères and show haplodiploidy, a approach to gender determination during which a fertilized egg develops right into a female and an unfertilized egg develops right into a male. In several dioecious species, males are shorter-lived and more compact without any digestive system and an individual testis. Females can develop eggs that happen to be effective at dormancy for protection all through harsh environmental situations.
