Re: Trout in an aquarium.
You need a chiller. I did it with hatchery rainbows for about a year and half with no chiller. it was VERY difficult keeping the water the proper temperature in the summer while maintaining a clean tank. Even with a TON of flow ( 400 gph thru an aggresive spray bar ) it wasnt enough to keep them happy and I came home one day to them both belly up. They get very large very quickly ( mine hit 13" in that year and a half in a 75 ) and are SUPER aggressive in the tank. What will end up with is you will have "one" fish in your big tank. They will eat anything smaller then them, and one will bully the other so that its always out of the main swimming channel. They get pretty boring pretty quick. My bluegill and shinners i have since replaced the trout with are far more interesting.
