just curious, anyone know where i can learn about either brook trout or rainbow trout? I read laws and so on and yes if they are farm raised, they are legal so nobody start. I have a 55g tank and only want one, and was wondering which is the smaller trout, which does better in water around 65, and so on. the filters on this tank are straight from a 300g, so i dont want to hear about how i will need a 1000g tank and im overcrowding. both options are about 3" right now. any help would be appreciated. THANKS!
