I started the banded killifish in the 0.34 acre pond I referred to with 8 fish. I now have thousands. The eastern silvery minnows were started with 15. I now have thousands.

Eastern silvery minnows appear to be far more tolerant of habitat extremes as compared to their western relative. They are also closely related to the brassy minnow.

I specifically set out to collect eastern silvery minnows after finding research showing their possibility as a pond candidate. I was able to catch 6 adults in August of 2011. I caught 9 more adults in April of 2012 and 27 YOY in August of that year. They were transferred to the pond. I first observed signs of reproduction in 2013 and had a huge spawn last year.
