Usually you'd create a request that contains a list of layers (the
same layer name repeated in this case) and a list of styles so
something like

http://localhost/geoserver/wms?request=getmap&layers=my_layer,my_layer&styles=fish,turtle&;.......

If your client is less smart then just add a bunch of layers all with
the same layer parameter and a different style for each one.
