Hi.
It's year 2 and just did a full water change on our little 300 gallon pond.
Found a few surprises when the pool was emptied.
First off, about a week ago I was out of town for 6 days and when I came
back I decided to do the water change as it was pretty mungy as I left. At
the time of leaving there were 5 fish (from the original 6) that survived
our mild winter: 3 goldies, 2 skubunkins(?) Now, after doing the water
change I found only 3 goldies, 2 tiny fingerlings (look like imported trout
from a friends wild pond), and 3 - 3" frogs!
My concern is, what happened to the 2 skubunkins while I was away? No
bodies found at the bottom. Neighbourhood cats? ..nah, the pond sides are
too steep and no plants we disturbed. Not aware of any raccoons in the area
either, and again nothing disturbed. So, do frogs eat 6" fish? Are the 2
tiny fingerlings that aggressive? How about the goldies as all 3 of those
survived. There are lots of tall everygreens surrounding the property and
thought there might be predators in those trees. But haven't seen any
eagles or herrons, etc. Perhaps they dropped by when they detected no
humans around for the week?

Your thoughts?
Thanks.
Jack
