Your first new species

Breed a Ferric Cod in a Spawning Basin, then farm iron nuggets with it in an Ecotone.

New fish come from mutations. Here you'll breed your first one, the Ferric Cod, from a pair of cod, then move it to your Ecotone where it yields iron.

You'll need

  • a Spawning Basin
  • a glass block
  • 2 Raw Cod
  • a few Iron Nugget
  • Wheat Crops or Fish Meal
  • water and power
  1. Build a Spawning Basin with glass on top.

    The glass becomes its tank. Fill it with water from a bucket or your Aquifer, and give it power.

  2. Load it.

    Two cod in the parent slots, wheat in the food slot, and an iron nugget in the catalyst slot.

  3. Wait for the mutation.

    Every 10 s it breeds. Each time there's a 5% chance of a Ferric Cod, using up the nugget; otherwise you get another cod. That's about 20 breedings, around 3 minutes, on average.

  4. Get a second one.

    A pair needs two. Keep the Basin running with more nuggets until you have another Ferric Cod.

  5. Farm them.

    Swap the cod in your Ecotone's row for the two Ferric Cod. Each time they breed there's a 66% chance of an iron nugget in the row's resource output, and sometimes another Ferric Cod to start a second row.

What you did#

You've run the loop that drives the whole mod: mutate in the Basin, farm in the Ecotone. Every other species works the same way, with its own parents and catalyst.
