Sunset Variatus High Fin
Sunset Variatus High Fin
Sunset Variatus High Fin (Xiphophorus variatus) is a Xiphophorus variatus combining a warm sunset gradient — orange fading to yellow — with a dramatically enlarged high dorsal fin in males. The high dorsal fin is a selectively developed trait that gives males a dramatically enlarged, sail-like dorsal fin. The Variatus Platy is a distinct species from the Southern Platy — slightly larger, with more natural color variation, and notably more tolerant of cooler temperatures. Ideal for unheated aquariums and outdoor tub ponds in temperate climates.
Feeding & Care Tip: Sera Vipan Tropical Flakes and Hikari Mini Algae Wafers make excellent daily staples — platys have a strong herbivorous lean and the algae wafers reflect their natural diet. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp, Hikari Frozen Daphnia, or Hikari Vibra Bites. For fry, Sera Micron Fry Food is an ideal first food.
Native to rivers of Mexico — particularly the Río Pánuco drainage in eastern Mexico. Xiphophorus variatus is a distinct species from the standard Southern Platy, slightly larger, with more variable and complex natural coloration — the species name variatus ('variable') reflects the wide natural color variation in wild fish. The Variatus Platy is somewhat hardier and more tolerant of cooler temperatures than X. maculatus.
Keep in groups. Keep two females for every male — male platys are persistently amorous and individual females will be harassed constantly without sufficient companions to distribute male attention. Compatible with virtually all small, peaceful community fish. Platys prefer hard, slightly alkaline water — they do better in harder water than in soft, acidic conditions, making them excellent choices for hard-water community aquariums.
Platys are prolific livebearers — a single female produces 20–80 fry every 4–6 weeks. Females retain sperm, so a single mating results in multiple successive broods. Dense planting provides cover for fry. Sera Micron Fry Food is an excellent first food for newborn platys, which can graduate to crushed flake within a few weeks.
