Rainfall varies spatially across southern Florida so that the inland marshes and Lake Okeechobee only receive about 60 percent of the rainfall levels recorded in the coastal areas (Gunderson and Loftus 1993). https://doi.org/10.1007/s10750-013-1697-0, DOI: https://doi.org/10.1007/s10750-013-1697-0, Over 10 million scientific documents at your fingertips, Not logged in O'Connor, J.H., and B.B. Citation information: U.S. Geological Survey. In an 8-month mesocosm experiment, we examined how a simulated Everglades aquatic community of small native fishes, snails, and shrimp changed with the addition of either a native predator (dollar sunfish Lepomis marginatus) or a non-native predator (African jewelfish Hemichromis letourneuxi) compared to a no-predator control. Much like the African jewelfish the swamp eel has similar feeding habits as many fish in the Everglades, which causes over competition for their food source and causes native species to die out from not having enough food to go around. Now, its primary water source, other than local rainfall, would be a system of artificial canals. Wetlands. Rader, R. B., 1994.

One small native fish (Heterandria formosa) was significantly less abundant in Hemichromis tanks, but there were no significant treatment effects for Gambusia holbrooki, Jordanella floridae, or Pomacea paludosa (applesnail).
