Steal Fish Eggs Beginner Guide: First Eggs, Fish, and Money

In Steal Fish Eggs, the core loop is simple: retrieve an egg from a guarded fish, place it in your tank, hatch it into a fish, and claim the fish to earn money. Your first verified action is to swim up to a fish being guarded by a parent and take its egg — the guarding fish will chase and can hit you, so be ready to juke or outrun it. This guide walks you through that first loop and introduces the training and upgrade activities you'll see as a new player.

Your first egg

Eggs are found across named zones shown in-game: Coral Reef, Deep Ocean, Pearl Lagoon, Snowy Sea, Volcano, and Jelly Ocean, with deeper or end sections containing fish you're likely too slow to steal from at first. Before attempting a steal, check the recommended swim speed displayed near the egg. If the guarding fish is faster than you, the attempt will probably fail — so stick to areas where your current speed is sufficient.

Hatch the egg and collect a fish

Once you have an egg, the game prompts you to "place the fish in your tank." Put the egg in your tank and hatch it to get a fish. Eggs carry visible rarity labels — examples include a sea turtle egg marked "rare" and a snowfish egg marked "basic" — and hatched fish are named species such as goldfish or Mohawk Tang. You'll know the hatch is complete when the fish visibly swims in your tank.

After the fish hatches, claim it to receive money. The money is your main reason to repeat the loop: more eggs, more fish, more income.

Fish take up tank slots

Each fish occupies an active slot in your tank. The UI shows counts like "six out of 10 active," and once you see "your tank is full," you'll need to either buy more equip/slot capacity or unequip existing fish to make room for new ones. Slot capacity is one of the first real constraints you'll hit.

Training and upgrades

Several progression activities are visible from the start:

• Tank upgrades: Additional tanks and slots must be unlocked and upgraded, and these are expensive — an upgrade costing a million in-game currency was shown in gameplay, so expect a grind before large tank expansions.
• Swim training: A "five plus swim" upgrade exists, and swim speed directly determines which eggs you can steal, since each zone lists a required speed near its eggs.
• Trail shop: A shop sells colored swimming trails as cosmetic purchases, with example prices in the single-digit Robux range shown at the time of recording.
• Egg growth: A paid "skip growth" option exists if you want to skip the hatching wait.

Exact costs and upgrade effects vary, so check the current in-game prices before planning purchases.

What to do next

Complete one full loop: retrieve an egg from a zone your swim speed supports, place it in your tank, hatch it, and claim the fish for money. From there, work on your first swim training upgrade to unlock faster zones, and keep an eye on your active fish count as you approach your tank limit.
