The mastery challenges have been updated and now include a lake called Laguna Iquitos which, from the looks of it, is located in South America. I'm guessing this means the new lake will be out this week?
Both species are part of the Tier 1 challenges. I am curious what other species the lake will feature. Arapaima and Pacu make sense but other species already in the game not so much or am I mistaken? Makes me wonder if there will be new ones besides the peacock and wolf fish.
