The Red Wagtail Swordtail (Xiphophorus helleri var. "Red Wag") is a classic, hardy livebearer distinguished by its brilliant crimson body and striking jet-black fins. Highly active and peaceful, this male variant adds vibrant contrast and dynamic movement to freshwater community aquariums, making it an enduring favorite for hobbyists at all experience levels.

Short Description & Highlights

The Male Red Wagtail Swordtail features an eye-catching bright red coloration offset by dark black markings on its dorsal and caudal fins, accompanied by the signature elongated lower caudal lobe (the "sword") unique to males. Reaching up to 5 inches, this robust swimmer adapts readily to standard community setups. Beginners will appreciate its hardy nature and ease of care, though it thrives best in slightly hard, alkaline water with plenty of open swimming room.

Detailed Beginner Care Guide

1. Aquarium Setup & Social Dynamics

Swordtails are exceptionally active top-to-middle water swimmers and require a well-secured aquarium with a tight-fitting lid, as they are strong jumpers. Because this is an individual male specimen, ensure your community tank includes a peaceful mix of other community fish or female livebearers to keep social structures balanced. Providing dense background vegetation mixed with open swimming channels creates an ideal environment.

2. Water Quality & Parameters

Unlike species that prefer soft and acidic water, Red Wagtail Swordtails thrive best in moderately hard, alkaline water conditions. Maintaining stable water parameters through routine partial water changes is essential. They appreciate stable temperatures between 72°F and 82°F and proper biological filtration to process their active metabolism.

3. Feeding & Nutrition

As enthusiastic omnivores, they accept almost any food offered. Provide a high-quality staple flake or micro-pellet supplemented regularly with vegetable matter (such as spirulina flakes or blanched zucchini) and occasional frozen treats like brine shrimp or daphnia. A varied diet ensures optimal coloration and long-term vitality.
