Steal Fish Eggs Guides
Every how-to for the swim-and-steal loop — from the first nest to the next biome drop.
Steal Fish Eggs is a short loop with a long Speed curve. You leave the safe zone, steal a fish egg from a nest, outrun the parent boss, hatch the egg in your tank, and spend the income on the endless pool and Trails. These guides break that loop into the searches players actually type: how to steal, how to escape bosses, how to get Speed, how to hatch, mutations, how to protect, and how biomes work.
Start here if you are new: Getting Started. If you already have a tank full of weak fish, skip to how to steal eggs and best fish. If a jellyfish just deleted your run, read how to get Speed before you swim that far again.
The core loop
- Train. The endless pool sits outside your tank. Swimming there raises swim Speed. Details in Speed training and the Speed guide.
- Buy a Trail. The Trail Shop in the safe zone sells seven Trails from 1.5x to 8x. Rankings live on the trails tier list.
- Steal. Grab an egg, turn around, do not fight the boss. How to steal eggs covers nest reads and escape paths.
- Hatch. Place the egg, wait, then keep or replace. How to hatch explains timers, sizes, and mutations.
- Defend. Other players on the 6-player server can steal your fish. How to protect your base and steal from players are a pair.
- Push out. Farther water needs more Speed. Biomes and map tracks the safe zone versus distant nests and the 13 September biome drop.

Use the fish index when a hatch lands and you do not know if it is an upgrade. Use codes only as a side bump — there are no confirmed strings yet. Use scripts only if you accept account risk; this hub is for playing the game as shipped.
Bosses you will actually see
Official thumbnails show a pink jellyfish guarding a nest (with a Jellyfish Egg income callout) and a shark chasing a thief who is carrying a textured egg. Trails matter because Sportskeeda’s trail guide notes they help while escaping bosses. Do not stand still to admire the model. Pickup, turn, swim to the safe zone. If you are too slow, drop the plan and train — the Speed guide is cheaper than repeating a failed far steal.
Update-aware reading
Kaiju Outbreak Official scheduled more fish, a new biome, and new features for Sunday 13 September 2026 at 2:00 PM UTC. A rebirth system has been rumored by writers covering the game; it is not confirmed. Until that patch lands, follow the loop above. After it lands, start with September 13 update then come back to biomes and the fish tier list.
Every guide page on this hub links to at least two siblings. If you finish Getting Started, your next two clicks should be steal eggs and Speed. If you finish hatch, your next two clicks should be fish index and protect. That is how you avoid a pretty tank that still dies to the first raid.
Frequently Asked Questions
Quick answers to the most common Steal Fish Eggs questions.
Which Steal Fish Eggs guide should I read first?
Open Getting Started unless you already understand the steal-hatch-train loop. Then steal and Speed.

Do I need codes before the guides?
No. Codes are empty for now. Train and steal instead.
