I have a 75 gallon tank that I'm not using and I thought it would be cool to try trout for a change. I've had native fish before but only bass, bluegill, perch, etc. I already have a powerhead (I originally bought it for my monster tank but it was too much for my gar and arowana to handle). I think it creates the right amount of current for trout. I have two 90 gallon filters so I'm assuming I'm good on filtration. I live in Michigan so I was wondering what species I could try and collect nearby? We have brown trout, brook trout, lake trout, and rainbows (I see rainbows more than anything in the creeks by my house). I've heard that rainbows can tolerate warmer water than the others so I was planning on going with those (plus they look a lot nicer imo). I don't have the money to buy a chiller right now so I was wondering if you guys think I'll need one? Also, assuming I started with two 5-6 inch trout, what else could I try housing with them?
