Top 5 Tameable Creatures in Subnautica 2 and How to Tame Them

Taming and Companions in Subnautica 2

While Subnautica 2 is not a traditional taming game, several creatures can be befriended, hatched from eggs, or recruited to help you survive. Some provide resources, others provide companionship, and a few actively defend you. This list covers the top 5 tameable or companion creatures and exactly how to get each one.

1. Cuddlefish - The Best Companion

The Cuddlefish is a small, friendly creature that hatches from a hidden egg. Once hatched in an alien containment unit, you can release it into the ocean and it will follow you, play with you, and even distract minor predators. It does not fight but provides valuable morale and companionship during lonely deep dives.

How to get it: Find Cuddlefish eggs in specific deep-cave locations (often near time capsules or story pods). Place the egg in an alien containment unit attached to a large room, and wait for it to hatch. Then release it near your base.

2. Stalker - The Scrap Collector

Stalkers are normally aggressive, but they have a unique behavior: they love scrap metal. If you drop salvage near a Stalker, it will carry the metal around and occasionally drop Stalker Teeth, a key resource for enameled glass. By feeding scrap to a group of Stalkers you can farm teeth passively.

How to use it: Find a kelp forest with Stalkers, drop several metal salvage pieces, and wait nearby. Collect the teeth they drop. This is not true taming, but it is the closest thing to domesticating a predator.

3. Crashfish - Defensive Symbiote

Crashfish live in sulfur plants and explode when threatened. While you cannot truly tame them, you can harvest their sulfur and use the plants as a natural defense perimeter around shallow bases. Some players build alien containment with Crashfish to study them safely.

4. Reginald - High-Value Food Fish

Reginalds are large edible fish that are among the most nutritious in the game. You can breed them in an alien containment unit to create an infinite food supply. A single containment tank with two Reginalds will multiply over time, giving you a steady stream of high-value food for the bioreactor or cooking.

How to breed: Catch two Reginalds with a gravity or propulsion tool, place them in alien containment, and wait. They will lay eggs that hatch into more Reginalds.

5. Peeper - Enzyme Carrier and Food Source

The humble Peeper is one of the most versatile fish in the game. It is a solid food source, a bioreactor fuel option, and in the story it carries a special enzyme that helps fight infection. Breeding Peepers in alien containment gives you an endless supply for food, fuel, and quest progression.

How to breed: Same as Reginalds: catch two, place in alien containment, and let nature take its course. Peepers breed quickly and are the easiest fish to farm.

Alien Containment Tips

• Build alien containment in a multipurpose room with a hatch on top.
• Place flora inside to create a self-sustaining ecosystem that feeds the fish.
• Keep predator and prey fish in separate tanks to prevent them from eating each other.
• Limit each tank to one species to maximize breeding efficiency.
