In the world of Palia, there are plenty of fish in the sea that players can catch. Some of these are much more common, like a Yellow Perch or an Albino Eel, or they can be incredibly rare, like a Long Nosed Unicorn Fish. Although you might think that all common fish are easy to get, some have additional prerequisites that you must meet. To get a Black Sea Bass, for example, you won't be able to just fish in any body of water to get it. Instead, there is a particular process you will need to follow to get the creature on your line.
