I am located in upstate western New York near Naples NY. I collected this little sunfish accidentally from my backyard pond when getting plants and water to get Daphnia and Cyclops for my minnow, I discovered him in the bucket back at my house so put him in with my minnow. It has very little color yet and is only just beginning to not be completely see through. It is about 3/4 of an inch (2 cm) long. I am not familiar enough with juvenile sunfishes to be able to identify the specific kind. I am used to catching ones that are at least a couple inches long and have all their color, this little guy is smaller than the hooks I use! Hope my photos are some help, he won't stay still for long so I have to get the photos fast.
Thanks for any help.
