Wandering Eye Fish

The Wandering Eye Fish is a pre-Hardmode enemy which can be spawned by fishing in a Blood Moon. When the player successfully catches a fish, a Wandering Eye Fish or a Zombie Merman has a chance to spawn in place of a fish. It can kill any unprepared player in a few hits.

It has a similar appearance to Demon Eyes and Wandering Eyes, being named after the latter. Instead of severed nerves and blood vessels trailing from its rear, it sports red fins. It closely resembles the Fish of Cthulhu.

Tips

 * The Wandering Eye Fish has high health and defense, and it also doesn't take knockback.
 * One way to effectively fight the Wandering Eye Fish is to obtain a movement accessory such as a Cloud in a Bottle or Rocket Boots and make tight circles around the enemy. Its top speed may be too fast for underequipped players, but its turning radius is easily outclassed.
