Im curious about that too.
How long can they survive on the Bait you put in there?
I had a dozen minnows in my Live tank for almost two weeks. I fed them Gold Fish food every third day.
They probably dont eat that good in a lake though.
Is your Minnow trap up near the surface or did you sink it down to the bottom?
The reason I ask is my lake is very public and lots of traffic will bring at least one curious person that would pull the trap just to see what it is.
I just wish I could be better at fishing. Or maybe luckier!:D
