Trout?

What's the question?

You'll need strong currents and lower temps than that IMO. I know trout are happiest when temps are in the 30's and low 40's. Try to duplicate a stream enviornment as closely as possible. I was thinking about doing the same thing.

Very hard to keep in aquariums. Size is the big issue--but they are also very territorial. Our fisheries biologists have a display tank, a 150, and they will not even try putting trout in there--it just won't work for very long. They can tolerate the warmer temps, but the nitrogen levels frequently are just too high (even in a cycled tank--0 ppm doesn't mean no ammonia, just less than .1 ppm) for long term survival.

I have heard of it being done before. However, I think they are one of the more difficult natives to keep. I can't recall the exact place I read that, since I have never had a desire to keep them.

I can't imagine a 150 being nearly big enough for trout. Trout are excellent jumpers and like a whole lot of swim space.

A single rainbow by itself might work until it gets to around 8 - 10 inches. Brown trout require cool, well oxygenated water and are aggresive and territorial. This is why most overseas trout farms are stocked with non-native rainbows. When I lived in Scotland there was a rainbow trout farm connected to this small river and during a flash flood, a half million of them went into it. lol they were so tame we could catch them on shiny hooks.
