About Guppy Time

A friendly way to put a proper name to a fancy guppy.

Guppy Time reads a guppy photo and describes it the way a breeder or judge would: by colour class, pattern and tail shape, following the International Fancy Guppy Association (IFGA) naming system. It's built for hobbyists, breeders and the simply curious.

How the identifier thinks

When you submit a photo, it's resized and re-encoded on our server, then sent to a vision-capable AI model with an IFGA classification brief. The model is asked to judge only what's actually visible — never to invent traits — and to report how confident it is, plus any genuine ambiguities such as blue-versus-green lighting or a borderline tail angle.

Why confidence and ambiguity matter

Guppy classification is genuinely hard from a single photo. Lighting changes colour, angle hides tail shape, and resolution blurs fine pattern work. Rather than pretend otherwise, Guppy Time shows a confidence badge and an honest note when something could reasonably be read more than one way. Treat every result as a well-informed estimate, not an official judgement.

About the guppy

The fancy guppy (Poecilia reticulata) is one of the most popular freshwater aquarium fish in the world, bred into a huge range of colours, patterns and tail shapes. If you'd like to learn the naming system yourself, the guppy types guide walks through every category.
