There was a study in Copaeia (sp) several years ago on one of the marsh
killies, perhaps confluentus. It laid it's eggs in the grasses at high tide.
I seem to recall (sorry, it's been a long time) that they hatched at the
next high tide. This is an interesting form of egg protection and hints at a
certain annualism in one of the North American Fundulus. Obviously not a
fresh water situation, but fascinating anyway.

All the best!
