Unfortunately they only do a mediocre job of mosquito control. People and
agencies introduce them based on their common name, not the other way
around. I'm guessing that's why BG is upset about the common
name. Besides, Gambusia are responsible for an array of environmental
problems resulting from unwise stocking for supposed mosquito control, such
as eating tadpoles and competing with native fishes and amphibians for
food. There's a paper on the redlegged tree frog of California where the
authors blame introduced mosquitofish on the decline of this rare
species. I have that paper if anyone wants a copy.

But they aren't a killifish either :-) as pointed out by Bob Muller and
others.

How about not calling any fish a mosquito fish because doing so only gives
mosquito control agencies a reason to think exotic fish introductions are
good and they're able to convince the public they are doing a "natural" thing.
