Green sunfish hammered the crawfish?
I never would have guessed that.
My sunfish are much too small to eat the crayfish. I don't think I've ever seen one (in this area) large enough to do the job.

Half acre 30 year old farm pond, Mebane NC. Aeration & feeder.
LMB, CC, SC, BG, HBC, two no account welfare carp and nine seasonal Tilapia that all the other fish are terrified of.
