Yeah I knew wallleyes prefer colder water, that is why they stay deep in lakes in the day and come to feed at night when that water is cool. Also they have those unique eyes to see at night which in one factor too.
I guess I had this stupid idea since the LFS puts walleyes,bass,sunfish, and bullheads together in a tank when selling them. They are just so dam active, even the walleyes but in my tank all the fish is kind of non active and very shy. Maybe it's because the LFS have people in there all the time and they get use to people, while I'm not in my room too much so when they say me they hide.
My room is in the basement and it's always freakin cold here. I use no heater at all and my water temp is always around 60-65 degrees. I just had this idea to slowly raise the temp to 70-75 degrees but I guess it rose too quickly then out of hand to 79-80 degrees. Also I forgot that colder water have more oxygen and by raising my water temp I lose the oxygen too.
Well I guess I'll learn as much as possible about these fish in captivities and hopefully by spring I'll have my new setup and there will be no flaws and smooth sailing for now on.
