Swordtail Free 3D Icon

Swordtail shows a small aquarium fish with the species’ signature extended lower tail fin, the little sword that gives it the name. Use it in pet shop apps, fish care guides, tank setup checklists, aquarium blogs, or species pickers for hobby tools. It is free for commercial use, and on the free plan you just need to give Thridy a credit.

Swordtail is a 3D render, carrying the same soft lighting and clean edges as everything else in the library. The download is a transparent PNG at full resolution, ready to place straight onto a layout.

It earns its place in pet-care apps, veterinary sites, wildlife education pages and children’s learning apps, and works particularly well for pet brands, veterinary clinics, conservation organisations and edtech.

Sizes on offer are 1024, 512, 256, 128, 64, 32, 24 and 16 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
