Low Poly Fish: Trout, Koi, Perch, Catfish & Silverfin

Five chunky low poly fish, ready to drop into a pond, a river, a fishing game or a bucket.

5 fish: River Trout, Moon Koi, Perch, Catfish and Silverfin, each as a prefab.

20 animations (4 per fish), all looping, in place, at 60 fps:

Idle: hovering, with a slow tail sway and paddling fins

Swim: a wave runs down the body to the tail

Swim_Fast: a bigger, faster wave with the fins tucked

Flop: a landed fish slapping its tail (the catfish thrashes on its belly instead)

Light on performance: 434 to 498 triangles per fish, one 1024 x 1024 texture and one material shared by all five.

Simple rig: 8 bones (a head, three spine bones, the tail, two pectoral fins and a root), Generic rig, at most two bones per vertex.

Ready to use: each prefab has an Animator Controller with one state per clip, so switching clips takes one line of code. A demo scene shows all five.

Render pipelines: Built-in out of the box. For URP, import the included URP/LowPolyFish_URP.unitypackage, which swaps the two materials for URP Lit versions.

Sizes are real-world, in meters: from a 0.30 m perch to a 0.98 m catfish.
