Steal Fish Eggs Fish List: Verified Fish Names and Properties

Fish confirmed to exist in Steal Fish Eggs include the Goldfish, Mohawk Tang, Sea turtle, Snowfish, an unnamed purple octopus, and a fish whose name is phonetically heard as "Rais" (exact spelling unconfirmed). Only two rarity labels are verified: the Sea turtle egg is labeled Rare, and the Snowfish egg is labeled Basic. No complete or official fish index, full rarity scale, income values, or size/mutation data exist for any fish yet, so unknown attributes below are recorded as unknown rather than guessed.

How collection works

In Steal Fish Eggs, you steal fish eggs from fish in the water, hatch them in your tank, and earn money from your fish. The official game description confirms the loop: "Steal fish eggs from fish," "Hatch fish eggs to collect rare fish," "Earn money from your fish," and "Discover rarer fish eggs, fish, sizes, and mutations!" Gameplay shows an active fish/equip slot limit in the UI — for example, filling from 6/10 active to 10/10 active — so your tank can only hold a limited number of hatched fish at once.

Reading rarity and other labels

Rarity exists as a real property on eggs and fish, but only two labels can be confirmed right now: Rare (Sea turtle egg) and Basic (Snowfish egg). No full rarity hierarchy or ordering between tiers is documented, so avoid assuming anything beyond "Rare is rarer than Basic" in spirit — treat each label as exactly what it says. Sizes and mutations also exist per the game description, but no per-fish size or mutation data is recorded, and no income values are attached to individual fish.

Fish identities versus variants

Treat a fish's base identity and its variants separately. The same fish can differ in size or mutation, which changes what you're looking at in your tank without making it a new species. For example, a Goldfish is a Goldfish regardless of any size or mutation difference. When checking this list, match on the base name shown in-game; the purple octopus is currently known only by appearance because no in-game name has been shown for it.

Where to go next

Once you've identified a fish here, compare the documented acquisition routes or review rare-fish evidence and limits. A dedicated income guide remains unpublished until its mechanics can be verified.

This catalog covers only the fish observed and named in-game so far. After fish additions, renames, or property changes, check the list again and verify names, rarity labels, and values directly in-game.
