Normal coldwater is neglected

coldwater all the way!
1st i'd get as many different sturgeon as i could find (the coolest fish IMO)
a Esox species, pike/muskie if they'd leave others alone. otherwise some big Chain pickerel
big gar
some big game fish like basses and perch / walleye
maybe some sweet native catfish

i'd do it up like a sweet Cabella's or Pro Bass Shop

 

[zennzzo]

Aros, Gars, Rays...and SCUBA gearthe standard Monster issue...
that would be about 16' Long x 8' Wide x 5' Deep, nice size "swim with the fishes" tank...

 

[chesterthehero]

large community of fish that would eat eachother
