Platies: How can I detect pregnancy, how often do the fish give birth?


I would like to know how I can see when the female platies will give birth.

the unborn fry are visible as a gravid spot (a dark spot diagonally above the anal fin). Just before birth, even the eyes of the fry can be seen through the skin of their mother.

Do they behave differently then?

They do so only insofar that they tend to retreat a bit and possibly hide in dense growing plants just before giving birth.

How long after giving birth does it take until they give birth again?

It usually takes about 4 weeks, but this also depends on the water temperature.
