Gold Platy
Xiphophorus maculatus
📍 Aquarium-developed colour morph; wild platies originate from Central America (Mexico, Belize, Guatemala), but the Gold variety is a tank-bred selective colour variant.
The Gold Platy is a vibrant, solid golden-yellow livebearer with a streamlined body and rounded fins, making it one of the most eye-catching colour morphs available in the aquarium hobby. Like all platies, it is peaceful, active, and social, thriving in community tanks where it spends much of its time in the middle water column exploring and interacting with tank mates.

Care Guide
Diet
Gold Platies are omnivorous and should be fed a varied diet of high-quality flake food and micro pellets as a staple, supplemented 2–3 times weekly with blanched vegetables such as spinach or zucchini. Occasional offerings of live or frozen foods like brine shrimp and daphnia promote colour vibrancy and overall health. Feed small amounts once or twice daily, only what they can consume in 2–3 minutes.
Behavior
Gold Platies are peaceful, active mid-water swimmers that spend much of their time exploring the tank and interacting with other fish. They are highly social and should be kept in small groups of at least 5 individuals; maintaining a higher ratio of females to males (at least 2–3 females per male) reduces aggression and harassment during breeding. They are curious and often approach the front glass at feeding time.
Breeding
Gold Platies are prolific livebearers that give birth to fully formed, free-swimming fry every 4–6 weeks without requiring a separate breeding tank. Females can store sperm and produce multiple batches from a single mating. In a community tank, most fry will be eaten by adults and tank mates; to preserve fry, provide dense vegetation or use a breeder box. They hybridize readily with other platy and swordtail colour morphs, so separate males and females if you wish to maintain pure Gold Platy bloodlines.

Same species, peaceful; may interbreed
Small, peaceful schooling fish; similar water parameters
Peaceful, similar size; may occasionally chase during breeding season
Peaceful algae-eater; occupies different niche
Common Diseases
Ich (White Spot Disease)
White spots on body and fins, rapid breathing, flashing (rubbing against objects), lethargy
Raise temperature gradually to 28–30 C (82–86 F) over 48 hours and maintain for 7–10 days; use aquarium salt (1 tsp per 5 gallons) or commercial ich treatment; perform 25% water changes every 2–3 days; ensure good aeration
Fin Rot
Frayed, ragged, or disintegrating fins; fin edges appear dark or black; lethargy
Perform 25–50% water change immediately; improve water quality and reduce ammonia/nitrite; treat with antibacterial medication (e.g., tetracycline or methylene blue) as directed; remove any sharp decorations that may damage fins
Fungal Infection
White or grey fuzzy growth on body, fins, or mouth; lethargy; loss of appetite
Isolate affected fish in a quarantine tank if possible; treat with antifungal medication (e.g., methylene blue or malachite green) following product instructions; improve water quality; maintain temperature at 24–26 C (75–79 F); perform daily 25% water changes
Shimmies (Nervousness/Mineral Deficiency)
Fish trembles or shivers in place; appears nervous or disoriented; poor appetite; may indicate low mineral content or poor water quality
Perform 25–50% water change with properly conditioned water; ensure adequate hardness (10–25 dGH) by adding mineral supplements if needed; check and stabilize pH and temperature; improve filtration and aeration; verify ammonia and nitrite are at 0 ppm
