Platies are cheerful, colourful livebearers available in a wide range of colour morphs. They are very beginner-friendly and tolerant of a broad range of water conditions, preferring slightly hard, alkaline water. Females give birth to live fry roughly every 28 days, so population management may be necessary.

Care Guide

Diet

Platies are omnivores and thrive on a varied diet of high-quality flake food as a staple, supplemented with spirulina flakes, frozen brine shrimp, and blanched vegetables like zucchini and spinach. Feed small amounts once daily, only what they can consume in 2-3 minutes. Occasional algae wafers support their vegetable intake and digestive health.

Behavior

Platies are active, social fish that spend most of their time in the mid-water column, though they'll explore all tank levels. They are peaceful and gregarious, thriving in groups of 3 or more where they exhibit natural schooling behavior and reduced stress. Males may display mild territorial behavior, but aggression is minimal compared to other livebearers.

Breeding

Platies breed readily in captivity with no special conditions required—females give birth to live fry approximately every 28 days when kept with males. Breeding is so prolific that population management is essential; separate sexes or provide dense vegetation for fry to hide and survive. Expect 20-40 fry per brood, though many will be eaten by adults without refuge.

Common Diseases

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots on body and fins, rapid breathing, rubbing against objects, lethargy

Treatment

Raise temperature gradually to 28-30°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich treatment; treat for 7-10 days

Fin Rot

Symptoms

Frayed or deteriorating fins, discoloration at fin edges, fin loss in severe cases

Treatment

Improve water quality with frequent partial water changes, remove any sharp tank décor, use antibacterial medication if secondary infection suspected; ensure good filtration

Velvet Disease (Oodinium)

Symptoms

Fine golden or rust-colored dust on body, rapid breathing, lethargy, scratching behavior

Treatment

Reduce light exposure, raise temperature to 28-30°C, perform daily 25% water changes, use copper-free velvet treatment; isolate affected fish if possible

Dropsy

Symptoms

Swollen abdomen, scales standing out like a pinecone, lethargy, loss of appetite

Treatment

Isolate affected fish immediately, improve water quality with frequent changes, feed high-quality food with added vitamins; prognosis is poor; euthanasia may be necessary
