I am in more or less the same boat as you.

I didn't even know I needed structure. I was going to haul a large tree trunk to the pond and float it. Didn't know I needed "structure".

I called a local radio talk show manned by two top area fisherman. I am not saying they are pond experts, the are fishing experts. They suggested Bluegill, LMB, a couple pike. They both agreed on that. Then in unisom they said "NO FATHEADS". I saw people suggesting fatheads and they said no fatheads or carp. The subject of catfish never came up. Should I get the same thing as you?

LMB
Bluegill
Channel cat (too cold here?)
fatheads?

I haven't heard of a redear?
