The Pecos pupfish
can usually be found and seems to thrive in saline bodies of water that
contain a limited number of other fish species. It occasionally lives in
fresher waters, but that is uncommon in such habitats. In the saline habitats,
populations can be very dense. Along the Pecos River, this pupfish
has most often been found in backwater areas and side pools that do not
have sunfish or other various other predators.
or behavioral adaptations:
pupfish is a very adaptable fish and can live in diverse conditions "from
water saltier than freshwater to seawater" with no problems whatsoever.
