This is what I would do if I had that tank: Set up a centerpiece consisting of large rocks, driftwood, an a few plants right in the center of the tank, right up through the surface; get a bunch of schooling fish that maxes out at about the 12" range; this gives the fish a perception that they are swimming in an endless waterway and they'll keep moving constantly. I would personally do something like clown loaches, silver dollars, and a large school of tiger barbs or tetras
Well, since i prefer to stick with native fish... My previously planned tankmate choices should b fine then. Was going to have black crappies, central stonerollers and pumpkinseed sunfish. I'll just take channel cat off the list 
So would the general consensus b that population would b fine in there? EVENTUALLY I'm getting 1000gal. But that's multiple years down the road. I'll save my massive catfish for then. I'd b happy with bass as my monster fish
