The YP I originally purchased from Rex (Rainman) five years ago were all feed trained. All offspring have remained feed trained. I recently cleaned 8 nice sized YP all caught at the north end of our pond (feeder and sunken cedar trees are all at south end). It’s only a 1ac pond, but when cleaning the fish, I was surprised to see the Optima BG feed in every one. I didn’t think they traveled around the pond that much.
5 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (way too many), SMB, and HSB (rumored..) I think that's about all I should put in my little pond.
After about 1 month the fry now stand together they have about 3/4 to 1 inch.
I would like to make a video, but you will see hundreds of tadpoles attract by the light an the food, but for the work they do I am ready to let them take some food from the fry, my pond is free to filamentous algae and clean.
I can't wait to see when the Yellow perch fry will start to spin under the light if the tadpoles will stay there.
