Thats a Very Interesting Theory about trout Nipping Each Other,
jbthwart77. I've had a Theory of My Own for awhile. I wonder if you put
a Plane Of Glass in the Aquarium, and put a Baitfish on The Other Side,
so that the Trout will Bump His Nose when he LUNGES for It, will he
then Remember That Fish when the Pane Of Glass is REMOVED?

If you TRY it, Let Us Know the RESULT.

TIA
