Xiphophorus maculatus
Platys have a short, stout, laterally compressed body with rounded fins. Wild forms are typically olive-brown with dark markings, but captive-bred varieties exhibit vibrant coloration including red, orange, yellow, black, and blue, often with variable fin shapes.

Physical characteristics
Platys have a short, stout, laterally compressed body with rounded fins. Wild forms are typically olive-brown with dark markings, but captive-bred varieties exhibit vibrant coloration including red, orange, yellow, black, and blue, often with variable fin shapes.
Habitat & distribution
Native to slow-moving streams, canals, warm springs, and ditches in eastern Central America, primarily Mexico and Honduras, featuring abundant aquatic vegetation.
Behavior
Peaceful, active, and social fish that thrives in groups; generally diurnal and non-territorial.
Diet
Omnivorous; feeds on algae, plant matter, small crustaceans, and insect larvae.
Reproduction
Livebearer (ovoviviparous); internal fertilization followed by the birth of free-swimming fry after a gestation period of roughly 24 to 30 days.
Ecological role
Acts as both predator and prey within its native aquatic ecosystem, consuming mosquito larvae and microalgae while serving as food for larger fish and birds.
Similar species
Swordtails (Xiphophorus hellerii) and Mollies (Poecilia sphenops). Swordtails are generally larger and males possess an elongated lower caudal fin lobe (sword), whereas platys lack this extension.
Identification tips
Look for the rounded tail fin (caudal fin), stocky body shape, and lack of the extended lower sword-like fin found in closely related swordtails.
Interesting facts
Platys are capable of storing sperm from a single mating to produce multiple broods of fry over several weeks without further mating.
