Well, heres an update...I picked up a large fake log decoration and it looks good and they like to swim through it but IMO, it'd look better in a CA/SA tank only. I also rearranged the tank.
My africans are too large to swim through the skulls eyes but my sun catfish is always in there because its the darkest. I think I might relocate him to my 75g but then my 4 line pimelodella catfish might not like it lol...
