Soft pastel pink is not a shade you expect from a swordtail, and that is precisely the charm of the Commet Pink (Xiphophorus helleri commet pink). Gentle colouring, the family's graceful tail and a thoroughly easygoing nature combine in a fish that makes a natural first livebearer, listed at a manageable 4.5 cm. Where louder strains compete for attention, this one calms a tank down — a pastel counterpoint to stronger reds and golds elsewhere in the aquarium.
Stocking around it is simple. Platies, mollies, guppies, other peaceful livebearers and snails are all listed companions, while large aggressive cichlids, fin-nipping fish, large predatory species, aggressive barbs and very delicate soft-water fish should be left out. Anything that requires acidic, very soft water is a mismatch — this strain wants the neutral-to-alkaline side, with pH 7.0–8.5 and hardness from 5 to 30 dGH. That preference is the single most important line in its care sheet: get the water right and everything else about this fish is genuinely beginner-grade.
A 75-litre aquarium heated to 23–27 °C is all it takes to get started. Keep maintenance rhythmical rather than reactive — small regular water changes hold the listed ranges far more easily than occasional big corrections. It asks for consistency, not expertise. The Commet Pink feeds as an unfussy omnivore, cruises the middle of the tank and, with routine care, lives around three years.

Getting started

Its easy-care rating and peaceful record make it one of the most forgiving introductions to livebearer keeping we can suggest. Start slow, stock light, and add colour gradually as confidence grows. Pick calm tank mates, keep up regular maintenance, and let the pastel colour do the rest. Fish arrive via licensed live-animal courier with a live arrival guarantee as standard.

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
