I am picking up 4 lbs of shiners today. I took an old 125 gallon aquarium I had in the basement with a few cichlids in it and am going to use it. I am getting large and crappie size for striper and crappie fishing. I got tired of paying $6.50 a dozen for the large and throwing them out at the end of the trip. I have a hob filter that drops water into the tank and turned off the heater so it should stay about 65 degrees. Any tips on how much to feed and change water etc. I have a bunch of flake fish food and guess that will be fine.
