Red Platy
Xiphophorus maculatus
Animalia›Chordata›Actinopterygii
Variety of Platy · red
📍 Central America
A platy variety selectively bred for uniformly bright red to brick-red coloration across the entire body and fins. One of the most popular and widely available platy varieties, it is extremely hardy and beginner-friendly, thriving in community tanks with hard, slightly alkaline water.
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.
Tank Mates
Similar size, peaceful temperament, and identical water parameter requirements make them ideal companions
Small, peaceful schooling fish that thrive in similar water conditions; keep in groups of 6+ for best results
Peaceful invertebrate that helps control algae and occupies different ecological niche without competing for food
Peaceful labyrinth fish with compatible water requirements; monitor for territorial behavior in smaller tanks
Schooling fish with similar size and peaceful nature; prefer slightly softer water but adapt well to platy conditions
Common Diseases
Ich (Ichthyophthirius multifiliis)
White spots on body and fins, rapid breathing, rubbing against objects, lethargy
Raise temperature gradually to 28-29°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich medication for 7-10 days
Fin Rot
Frayed or deteriorating fins, discoloration at fin edges, fin shortening
Improve water quality through frequent partial water changes, remove any sharp tank decorations, treat with antibacterial medication if severe; ensure water parameters remain stable
Velvet Disease (Oodinium)
Fine golden or rust-colored dust on body, rapid breathing, lethargy, loss of appetite
Increase aeration and temperature to 28°C, perform daily 50% water changes, use copper-free velvet medication; quarantine affected fish if possible
Dropsy
Swollen abdomen, protruding scales, lethargy, loss of appetite, pale coloration
Isolate affected fish immediately, maintain pristine water conditions with frequent changes, feed high-quality foods; prognosis is poor; antibiotic treatment may help in early stages
