Two classic swordtail traits meet in a single strain here: the bold tuxedo pattern and the flowing lyretail. The result is the Tuxedo Lyra Swordtail (Xiphophorus helleri tuxedo lyra) — a livebearer listed at just 4 cm whose elegant finnage looks almost outsized for its body. Lyretail forms trade nothing away in hardiness for their looks; this remains an easy fish in every practical sense, simply a better-dressed one. On the record it is rated easy to care for, peaceful in temperament and entirely conventional in its needs.
Good neighbours include other peaceful livebearers — mollies, platies and guppies — plus Corydoras and Otocinclus working the lower levels. Keep it clear of large aggressive cichlids, fin-nipping barbs, large predators and very delicate slow-moving long-finned fish, and skip anything that must have soft, acidic water; this strain prefers a pH of 7.0–8.5 with hardness from 5 to 30 dGH. It is a fish chosen as much for what you leave out of the tank as what you put in — with no nippers present, the finnage stays pristine and the strain shows exactly as intended.
Day to day it asks for very little: 23–27 °C, a tank of 75 litres upwards and the varied feeding any omnivore enjoys. A weekly partial water change and a steady heater are genuinely most of the maintenance story for a fish with ranges this forgiving. It keeps to the middle of the aquarium, stays peaceful with appropriate company and typically lives around three years.

Planning your stocking
Those paired lyretail points deserve protection, so be strict about excluding nippers when you plan the tank. In a calm community the Tuxedo Lyra provides constant gentle motion at eye level. Add it after the tank has matured, give it a dim first day to settle, and it rewards the patience — the pattern does the talking while you simply keep the water steady. Orders travel by licensed live-animal courier and arrive under our live arrival guarantee.

I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
