Ok, here's what i'd do.
Sand on the bottom.
On one end a small assortment of largish stones.
On the other End a largish tree stump with wood protruding out of the water in various spots.
Java fern or java moss tied to wood, and some water lilies.
1 Florida Strain Largemouth bass - Female
A school of red ear sunfish.
1-2 bullheads.
Crawdads.
Stainless Steel over head lights hanging by wire.
Not that, that would be a tank to end all tanks. Done right, zoo quality, but better.
I can just see your tank, a 23+ pound Largemouth, and a shimmering school of sunfish and the cats? Oh man, my dream right there!!!!
