Dr. Tamaru? Tell me more: where he wrote this. Saint-Jean & Bonu
(1994, Hydrobiologia 272: 147-161)  found, that M. micrura tends to
switch to sexual reproducion followed by a (temporary) crash of the
population. This is also my experience. Other species of Moina, such
as M. brachiata or M. macrocopa, seems to be better for cultivation.
If  have none of these.
