1. 1

   Size and Shape

   Adults typically reach 3-6 cm (1.2-2.4 inches) in total length, with females generally larger than males. They have a somewhat compressed, robust body.

2. 2

   Gonopodium

   The most reliable way to distinguish males from females is the presence of a gonopodium in males (a slender, pointed anal fin) versus a fan-shaped anal fin in females.

3. 3

   Coloration and Patterns

   While highly variable, look for the characteristic 'moon' or 'comet' spot near the caudal fin base, especially in wild-type or less selectively bred individuals. Domesticated varieties are identified by their specific color strains (e.g., 'Red Wag', 'Mickey Mouse', 'Sunset').

4. 4

   Behavior

   Platies are active, schooling fish that are often seen foraging among vegetation or near the water surface.
