Vicious Goldfish

Crimtane Goldfish are a type of Goldfish found only in the Crimson. With Corrupted Goldfish, they are the only type of attacking goldfish in Terraria. The Crimtane Goldfish is the Crimson counterpart to the Corrupt Goldfish.

Any regular Goldfish nearby just before a Blood Moon will be transformed into a Crimtane Goldfish if your world contains Crimson.
