Rare Fish Finder
by rasmus123d
Rare Fish Finder makes rare tropical fish easier to spot in the world, in buckets and in the collection screen.
What it does
Vanilla spawns the same 22 common tropical fish varieties most of the time. Rare Fish Finder is a client-side Fabric mod that marks the rarer varieties so a player can find them. Rare fish glow, their name tags show pattern colors above them, and an optional filter can limit the glow to rare tropical fish that the player has not collected yet. Only the client needs the mod, so a server can run without it.
The mod also extends the collection view. The fish collection screen tracks which variants a player has caught, with per-server catch counts, and bucket and chest tooltips show the real fish bucket icon with two color squares. Hovering over buckets and chests shows which fish a player already owns. The first catch of each variant triggers a toast that shows the live fish number, and finishing a pattern gives a larger celebration than a common one. Rare Fish Finder requires Fabric API and works with Mod Menu as an optional integration. Xaero's Minimap map filters are optional too.

How it compares
Xaero's Biome Filter is a Fabric client-side mod for 26.1 – 26.3 under the MIT License, and it filters biomes rather than fish. Tradecycle Finder is also a client-side Fabric mod under the MIT License, for 1.21 – 26.2, aimed at villager trades instead of fish. Mob Fishing is open source under the MIT License and runs on client and server for Fabric 1.21 – 1.21.1, so it changes fishing rather than fish finding.
