Hey Zoodiver. I'm planning to put a 200,000 gallon saltwater tank in my multi-purpose business. Yes. Huge project(well not compared to your famous 600,000 gallon). But anyway. It is freshwater, and I plan to make it look just like one of the great lakes, and flood it with plants and vegetation, and different species. I've developed a list of species (below).

Freshwater Florida Stingray
Shovelnose Cat/ Redtail Cat Hybrid
Redtail Catfish
Longnose Alligator Gar
Silver Arowana
Polypterus Endilcheri

With that being said lol. I know these are aggressive fish. But I thought the high number of fish would calm the aggression. Tell me what species you think I should take out, or add also. The tank will be very deep and wide and moderately long from front to back. So what Plants should I use? I'm going for a clean exotic and busy look. Lots of greenery, driftwood, and rock.
Also one other thing. How much will it cost to run the tank? Is there anyway to get by filtering the water 24/7 due to it's enormous size? Thank you.
