Honeyfin

The Honeyfin is a consumable fish that can be fished from Honey found in beehives within the Underground Jungle. Other than the Bumblebee Tuna found during Angler quests, Honeyfins are the only fish that can be caught in Honey.

If one is willing to spend some time fishing, Honeyfins are the most effective healing potions that can be obtained without entering Hardmode.
