I discovered this article in Aust Herald Sun news paper today 19th Oct 2007

From this page:

The mangrove rivulus is primarily a saltwater or brackish water species, with limited occurrence in freshwater. It can tolerate salinities from 0-68 parts per thousand. Within the Everglades and along Florida's west coast, this fish occurs in stagnant, seasonal ponds and sloughs as well as in mosquito ditches within mangrove habitats. Along the east coast of Florida, it resides in elevated marsh habitats above the intertidal zone, often within the burrows of the great land crab (Cardisoma guanhumi). This preferred microhabitat may provide shelter from cool winter temperatures, allowing for a more northerly distribution of what would otherwise be possible. Great land crab burrows also provide areas of refugia during the dry season, when seasonal pools of water dry up. Fish occurring in these burrows are small, with as many as 26 fish having been recorded in a single burrow. Burrows of other crab species may be utilized when the giant land crab is absent, particularly in areas of the west Florida coast. The mangrove rivulus is able to survive in moist detritus without water for up to 60 days during periods of drought, anaerobic, or high sulfide conditions. Intraspecific aggression may also induce individuals to move to other bodies of water. This fish has been observed slithering and flipping across land during the rainy season to reach pools of water or crab burrows containing water. Epidermal capillaries are used for respiratory gas exchange during times of adverse environmental conditions. Tolerating extremes in temperature and salinity, the mangrove rivulus survive in areas where few other fish species can exist.

Tough beastie.

Mind you I've posted in the past on Innes' observation that Rivulus of numerous species will climb out onto floating plants, "Velcro Jump" against the glass and adhere to it for periods of time, and engage in other weirdness of this ilk. Oh, according to this page Rivulus marmoratus is also a hermaphrodite. Interesting to put it mildly!
