Maintain these water conditions for optimal health and vibrant colors
Take the golden colouring of the Marry Gold line and finish it with a sweeping lyre-shaped tail: that is the Marry Gold Lyra Swordtail (Xiphophorus helleri mary gold lyra) in a single sentence. The lyra finnage doubles the visual impact of the gold without adding a gram of difficulty to the keeping — if you already like the colour, the fins are a free upgrade. Listed at about 6 cm, this colourful lyretail fills the middle of a community aquarium with constant activity, breeds readily, and asks very little in return — care is rated easy across the board.
Unlike some bolder swordtail strains, this one is recorded as peaceful, which makes it the easier choice of the two Marry Gold forms for a mixed community — its standard-finned counterpart is logged as semi-aggressive. It settles in well beside other peaceful livebearers — platies, mollies and guppies — with Corydoras and Otocinclus covering the lower levels. Keep it away from large aggressive cichlids, fin-nipping fish, very large predators and highly aggressive barbs, and avoid pairing it with anything that needs soft, acidic water.
Provide a 90-litre aquarium at 23–27 °C, with a pH between 7.0 and 8.5 and any hardness from 5 to 30 dGH. Keep the routine boring — same temperature, same weekly change, same varied feeding — and this strain simply gets on with looking good. Around three years is the typical lifespan on record for an omnivore kept this way.
Golden fish light up planted tanks, and the lyretail adds a flourish you simply do not get from standard-finned forms. Choose calm companions, protect those fins from nippers, and the display takes care of itself. Order alongside its listed companions and the whole community can settle in together. New fish appreciate a gentle, gradual introduction and a calm first evening in the tank. Sent by licensed live-animal courier; every order includes our live arrival guarantee.
