I've worked with gambusia for about 20 years in Ca and the south east.
The principle eaters of frog and toad eggs were salamanders. I thought
this a good thing as there were always more than enough eggs to go
around. The gambusia, though great in numbers, didn't seem to make a
difference in the populations of amphibians, but quite decimated the
mosquito population. I observed that the gambusia more often got into
the eggs and became entangled and died. Also when I had mosquitoes in
rain barrels, they all disappeared when the frog eggs hatched. Tadpoles
love mosquito eggs and larvae. I also grow Acorus calamus.
