Care Guide

Diet

Red Platies are omnivorous and thrive on high-quality flake foods and small pellets as their staple diet. Supplement 2-3 times weekly with frozen foods like brine shrimp, daphnia, or bloodworms to promote color vibrancy and overall health. Include vegetable matter such as blanched spinach or spirulina-based foods to support digestion and natural coloration.

Behavior

Red Platies are active, peaceful schooling fish that spend most of their time in the mid-water column, though they will explore all tank levels. They are highly social and should be kept in groups of at least 3, preferring a ratio of 2-3 females per male to reduce aggression and harassment. They are curious, interactive fish that often approach the glass during feeding times and display minimal aggression toward tankmates.

Breeding

Red Platies breed readily in captivity and are livebearers, making them excellent for beginners interested in breeding. Females produce 20-40 fry every 4-6 weeks once mature, with minimal intervention required beyond maintaining stable water conditions and providing dense vegetation for fry to hide. Separate fry into a nursery tank or heavily planted area to prevent predation by adults.

Treatment

Increase aeration and temperature to 28°C, perform daily 50% water changes, use copper-free velvet medication; quarantine affected fish if possible
