Swordtail

Swordtails are omnivores and thrive on a varied diet of high-quality flake food as a staple, supplemented with spirulina flakes, frozen brine shrimp, and bloodworms 2-3 times weekly. Include vegetable matter such as blanched spinach or algae-based foods to support digestive health. Feed small amounts once daily, only what they can consume in 2-3 minutes.

Swordtails are active, peaceful community fish that spend most of their time in mid-water zones, though they will explore all tank levels. Males are highly territorial and aggressive toward other males, displaying with their distinctive sword-like tail extensions; keep only one male per tank or maintain a 3:1 female-to-male ratio to reduce aggression. They are hardy, curious, and adapt well to established community tanks.

Swordtails are prolific livebearers that breed readily in captivity without special conditioning, making them ideal for beginners interested in breeding. Females produce 20-100 fry every 4-6 weeks; provide dense vegetation or a breeding box to protect fry from predation by adults. Separate fry into a nursery tank and feed infusoria or finely crushed flake food until they are large enough to join the main tank.
