Arapaima

The Arapaima is a swimming Hardmode enemy that spawns in water pools within the Jungle and Underground Jungle. It is immune to the Confused debuff. They swim much faster than most fish. Although dealing high damage, this enemy has very low knockback resistance, so high knockback weapons are useful.

Trivia
