Steal and Fish Rare Fish: Where to Look and What to Do With Them

Rare fish in Steal and Fish are found out in the world. The Roblox tycoon is built around exploring its biomes, and the catches you bring home go straight into your aquarium — filling that aquarium is how you complete your fish Index. So the realistic answer to "where do I look?" is everywhere the game lets you travel: leave your base, work through each biome, and get everything back before something catches you.

Where the rare catches are: out in the biomes

The game's own how-to-play description puts "collect rare fish" and "battle bosses in every biome" side by side, alongside fishing for mysterious eggs, escaping from dangerous bosses, and completing your entire Index. Read together, that tells you where to spend your time: every biome is a hunting ground, and every biome has a boss in it. Plan each trip as explore, collect, escape — the bosses are flagged as dangerous, so getting your catches home alive is part of the challenge, not an afterthought.

No specific biome is singled out for rare fish, so the dependable approach is covering ground region by region rather than camping one spot.

What to do with what you find

Bring it back to your base. Filling your aquarium with the catches you collect is how the fish Index gets completed — it's the collection goal the game points at directly: can you discover every fish? Space is the constraint to watch. Upgrading your aquarium is one of the game's listed activities, and in one recorded run a full base meant selling fish before anything new could be placed.

The egg detour

Mysterious eggs are the other thing worth grabbing while you're out exploring. In one recorded session, a player stole eggs from the large creatures guarding them, hauled them back to his base, placed them inside, and waited roughly one to two minutes for each to hatch. That run also showed the practical rules of egg theft:

1. Grabbing an egg starts a chase — the owner comes after you.
2. You can drop a carried egg at any point to flee. If a chase turns bad, the egg is expendable; you getting home is not.
3. A full base blocks new placements — sell some fish to make room first.

Nothing establishes which eggs hatch into what, so treat eggs as a bonus on the trip rather than a guaranteed rare-fish source. The eggs page covers the grab-and-run details.

Outrunning the guards

If chases keep ending your runs, speed is the stat one player leaned on: in that session he upgraded his speed stat again and again between egg runs and credited it with letting him outrun the guarding creatures and escape with the eggs. That's his approach rather than a rule the game states, but it fits the loop — explore, grab, run — and it's a low-risk investment for any trip that ends in a chase. Free codes can help fund upgrades like that along the way.
