How to catch Goby | Stardew Valley

You need to have level 10 fishing skills with Advanced Iridium Rod. You also need to purchase both Trap Bobber and Lead Bobber to facilitate fishing from Willy's Shop at Pelican Beach. Now head to the path at the south of your farm and try to head southwest until you pass the Wizard's tower and also the abandoned house. Then head east of the abandoned house again until you reach the edge of the waterfall. The waterfall in Cindersap forest is located at the southwest of Stardew Valley. Once you are there, cast your rod into the lake beneath the waterfall at maximum level and wait patiently for the fish to bite. Do take note that other fish may bite the bait as well and the Goby is a very rare fish. You need to cast multiple times to catch it.
