Goldfish

Goldfish are benign background water characters that cannot harm the player, similar to Bunnies and other critters. They have only 5 health and no defense, making them very easy to kill by the player or any enemy that passes nearby.

During a Blood Moon, or when hit with Vile Powder, Goldfish turn into Corrupt Goldfish, which have much more health and do attack players. These can be very dangerous for players with low-tier armor and weapons.

Tips
''Note: The following tips do not apply to the PC version 1.2.3 and later versions of the game. You now need to use a Bug Net to obtain the goldfish item instead of killing it. These tips still apply to the console version of the game only.''


 * The Fish Statue can be used to farm the Goldfish drop. Dart Traps or Lava can be used to kill the Goldfish as they spawn. (Doesn't apply past PC version 1.2.3)
 * Another farming method is to find a water body where Goldfish spawn, and corrupt one of them with Vile Powder. Further spawned Goldfish will be killed by the corrupt one, leaving behind the Goldfish item. The Corrupt Goldfish will likely despawn when off-screen for too long, and new Goldfish will not spawn while the entire water body is on-screen; keeping an area of the water off-screen may allow new fish to spawn while keeping the Corrupt one around. (Doesn't apply past the PC version 1.2.3)
