Yes, of course, but noone takes this behavior as it were ' a reaction '.
If offspring is so to speak universal important for the species- sake, by
a rapid drought other selection characteristics are forced upon the fish...
they have to " react ".
The matter of contention would be the question if the reaction were instinc-
tively, intentional or conscient.
The ' normal ' choise of the female would be outplayed completely.
IMO, natural selection ( seeing here in the common Darwinian way) plays
no role here_ the usual by sexual selection coupled choise of mates is
outrunned by the species will of survive. Which IMO is a far more
greater ' force ' than those environmental changes which do play a role
in the survival of any species.
Best,
Kenneth
