Galactic fish is a valuable catch in the Stardew
Valley game. This lovable creature can be found in the creek during stormy weather and at night. If you manage to reel in a Stardew eel, you can sell it for a handsome profit. In addition to its monetary value, it is
also in demand by fishermen for its ornate beauty. So, grab your tackle box and head to the streamside to try your luck at hooking this Cosmic heart fish. Happy fishing!
