Hi All,
I found out about yellow perch. Since they are schooling fish they like round tanks, They will go round and round. When I transfered them from the round swimming pool ( a leek in the bottom of the tank I couldn't stop) to the totes, they went straight to the corners and stayed there on the bottom.
The gold fish and blue gills go up and down in the column of water. They do very well in totes.
Also, the perch like to hide. I keep a net bag filled with bird netting tied off to float. The perch will hide under them. The bags do two things. First hiding place for fish. Second, the bags will pick up fine particles in the water. I wash these out every other day. It is worth it for happy fish.
