A Valheim completionist run often means that you must catch every fish in the game. And one fish that you can't miss out on is the Tetra Fish. However, finding it can be quite tough, and this search can take hours if you’re unlucky. So, here’s a guide on how to get Tetra Fish in Valheim to help you in this endeavor.

Tetra Fish Location in Valheim

Generally, catching the Tetra Fishing in Valheim is easier than finding it. The reason is that players can only find this fish in bodies of water inside Frost Caves in the Mountain biome. Although it sounds fairly simple, players must first find a Frost Cave (included in the Mistlands update) with a pool of water in it. The challenge here is that Frost Caves are fairly plenty, with some world seeds loading dozens of these locations. The alternate route is creating different world seeds that can spawn an easy-to-access Frost Cave.

Catching the Tetra Fish

Once you find a Frost Cave that spawns Tetra Fish in Valheim, you must use a specific bait to catch it. In particular, you must use Cold Fishing Bait, which you can craft by combining 20x Fishing Bait and 1x Fenring Trophy at the Cauldron. Note: Craft the Cauldron at the Forge by using 10x Tin. Be wary, as you’ll consume 1x Cold Fishing Bait each time you cast your fishing line. So, use your rod with this bait in places that spawn Tetra Fish, or you’re only wasting your time and resources.

Tetra Fish Usage

At the time of writing, the Tetra Fish in Valheim only serves two purposes – as an ingredient in cooking and a decorative piece. Additionally, this fish is a requirement to obtain the Fishing Hat, an armor piece that requires players to catch every fish in the game. Wearing the Fishing Hat provides a +20 Fishing Skill bonus. But you must catch the following fish to craft it:

• Anglerfish
• Coral Cod
• Giant Herring
• Grouper
• Magmafish
• Northern Salmon
• Perch
• Pike
• Pufferfish
• Tetra
• Trollfish
