He then gathers up the eggs in his mouth and blows them into the nest. . The male then tends the eggs until they hatch about 36 hours later.

CONSERVATION: IUCN Red List; Least concern.  M. opercularis has a large distribution area and there are no known widespread threats to this species.

REMARKS: Used as predators of mosquito larvae and to control Dengue Fever.

These fish are thought to be one of the first fish introduced to Europe as an ornamental fish, in the mid 1800s.

Males must be kept separate from each other in tanks to prevent fighting,
