i have had two walleye, three yellow perch and 3 blue gills for a year now. the walleye were 3 to 5 inches to start. they are now 9 to 14 inches. the big daddy is a horse nice and thick. i feed them 12 dozen minnows a week, and 5 days in theres nothing left. when you dump the minnows in its like the water starts boiling. when the lights turn off at 10 you can hear the gravel and plants moving and flying. my tank stays about 65 to 72 degrees year round "room temp". the fish are doing great and growing nicely. if you have any questions fee free to pm me.
