There are a few new collectable items in the form of fish!
Obtaining
The collectable fish are obtained through fishing, they're rarer than other fishing items!
The biomes of these fish can be found in the Blue text.
The description of these fish can be seen in Green text, this is how the angler describes the fish!
Collectable fish can be differentiated from regular / smeltable fish by their text colour, which is purple.
Uses
There is no technical use for most collectable fish apart from.. collecting them! hang them up with item frames, be proud!
The only Fish to have a functionality is the Lucky Fish, which increases the chances of getting better loot from fishing while it is in your inventory.
