Having trouble getting brown trout for Phelma quest?

Well thanks to my genius of being on the game for five years and finally found where I can finally fish that is just brown trout yesterday!!! I've been fishing in the other area in The Lookout and I would always get perch perch perch perch a couple of brown trout and some eels. Then I noticed something near the cave in the Lookout. More fish! I noticed they were all brown trout! Yes, all I would get is brown trout, some eels sure, but I am so happy!!! And I must say the view is amazing! My favorite fishing spot by far! I hope this will help you out instead of losing pateince and buy 80 gems of brown trout >_>
