Free fish 3D models for three.js (GLB, CC BY)
24 free fish for three.js from the 454 in the paprika3d asset library (CC BY), as meshopt GLB files: each with its author, license, credit line, triangles and file size, and the asset_search call that fetches it.
What the library holds
The paprika3d asset library holds 454 fish among its 57,732 models. All of them are licensed CC BY 4.0, which asks you to credit the author wherever you use the model; each card below carries the credit line to paste. 1 are AI-generated, from Scenario's 3D Collection, and say so on their card.
438 of the 454 pass the library's quality checks: textured (or drawn in vertex colours, for a low-poly or voxel model), not flat, at most 15 MB, with a name, a description and a real-world height. Among those, the median model has 3,560 triangles, with the middle half between 3,220 and 8,860, and the median file is 0.23 MB, with nine in ten at most 0.6 MB. The median one stands 0.3 m tall at real size. 1 carry a texture of 2048 px, the library's largest; the rest are smaller. 53 are animated and 50 rigged. The most common styles are stylized (257), realistic (93) and toon (37).
Fish in a three.js scene
Several fish on this page share one base mesh of 3,562 triangles, textured differently by different authors, which makes a varied school cheap: one geometry, several materials. A school is an InstancedMesh per fish type, each instance turned to face its direction of travel.
Fish swim with their bodies. Without a clip, bend the tail in the vertex shader: in onBeforeCompile, offset each vertex sideways by a sine of the time and its position along the body, weighted so the head barely moves. Of these, 53 are animated and 50 rigged, and those swim from their own clips.
Underwater, scene.fog = new THREE.FogExp2(color, density) with a blue-green colour and a matching background hides the tank's far wall. Whales and sharks here are full size, up to 3 m, beside fish of 0.15 m, so check each card before putting them in one tank.
Fetch one and load it
With the paprika3d plugin in Claude Code, or its MCP server in any other agent, the agent searches the library in words or picks a model by the id on its card. pick downloads the file into the project's assets/ folder (public/assets/ under vite), adds the credit line to assets/CREDITS.md and answers with the code that loads it at real size. Give cwd, the project folder, as with every paprika3d tool.
asset_search {"query": "fish", "cwd": "."}
asset_search {"pick": "f7e2e4858f2f438aa2832566220199f4", "cwd": "."}
Every file is a binary glTF (.glb) compressed with meshopt, so GLTFLoader needs the meshopt decoder that ships with three.js. The origin sits at the bottom centre of each model, so it stands on the floor where you place it:
import * as THREE from 'three';
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';
const loader = new GLTFLoader().setMeshoptDecoder(MeshoptDecoder);
const gltf = await loader.loadAsync('assets/koi-fish-f7e2e4.glb');
scene.add(gltf.scene);
24 fish to start from
Chosen from the 438 that pass the checks: the ones agents picked most through asset_search first, then the ones whose name says what they are, then lighter files, with at most 2 per author. Each CC BY card ends with its credit line: paste it into your credits, as the license requires.
