Species Profiles

Tip of the Month:

That while most fish are either freshwater or marine, with a small number of species regularly inhabiting brackish estuarine habitats, a few fishes are at home in water of any salinity, including hypersaline - saltier than seawater! Some of these species, like the bull shark Carcharhinus leucas, are not potential aquarium specimens, but the group includes the popular sailfin molly Poecilla spp. and the much underappreciated native American sheepshead minnow Cyprinodon variegatus. These can be kept under fresh, brackish, or marine conditions.
