Overview The Pink Comet Swordtail is a stunning and unique variant of the popular Swordtail fish (Xiphophorus hellerii). Known for its elongated, sword-like tail and vibrant pink coloration, this active freshwater fish makes a fantastic addition to community aquariums. With its hardy nature and adaptable temperament, the Pink Comet Swordtail is a great choice for both beginner and experienced fish keepers. Origin Native to Central America, particularly Mexico, Honduras, and Belize, Swordtails are naturally found in fast-flowing rivers, streams, and lakes. Through selective breeding, the Pink Comet variant has been developed to showcase its beautiful pink hues while retaining the characteristic sword-like tail of the species. Feeding Pink Comet Swordtails are omnivores and require a balanced diet of both plant-based and protein-rich foods. They thrive on: High-quality flake or pellet food Live or frozen foods such as brine shrimp, daphnia, and bloodworms Blanched vegetables like spinach, zucchini, and peas for fibre Providing a varied diet ensures vibrant coloration and overall good health. Tank Mates Pink Comet Swordtails are generally peaceful and social, making them excellent additions to community tanks. Ideal tank mates include: Other Swordtails Platies Mollies Guppies Tetras Corydoras catfish Peaceful dwarf cichlids (such as Apistogramma) Avoid keeping them with fin-nipping or highly aggressive species such as some larger cichlids or barbs. Aggression & Behavior While mostly peaceful, male Swordtails can display aggression towards each other, especially in smaller tanks or if competing for mates. It’s best to maintain a higher ratio of females to males (at least 2-3 females per male) to reduce aggression. Providing ample swimming space and hiding spots with plants and decorations helps mitigate territorial disputes. Experience Level Beginner-friendly. The Pink Comet Swordtail is an easy-to-care-for species, making it ideal for newcomers to the aquarium hobby.
