I have seen a Limpkin feeding on them in the mangroves. There are several fishes that come out of the water and hang out on land. One interesting fact is that this little killifish does show natural selection. It is believed that snakes and birds can find the killifish that contrast with the bottom and eat them more quickly than those that blend in with the bottom of their pools. Of course, it gets interesting when the fish leaves the water to catch land insects and bugs including termites. Most of the killifish are hermaphrodites having both male and female reproductive organs. These embryos are released from the body of the killifish and hatch 2 to 4 weeks later if they aren't consumed by other killifish (including their parent) before hand. All in all, this unique little fish is something that excites scientist and that many hope will stay around a little longer. Another interesting thing is that the eggs can survive without water. Mangrove rivulus are tolerant of poor water quality and pollution and are extremely tolerant of salinity and temperature variations. The mangrove rivulus has a long, slender, dorsally flattened body and a rounded caudal fin. Eggs hatch in two to four weeks and only require dampness, not standing water.
