🧼 Water Parameters
Test water weekly with an aquarium test kit.
Perform 25–50% water changes weekly to maintain water quality.
Avoid ammonia and nitrites; keep nitrates low (<40 ppm).
🐠 Diet
Swordtails are omnivores and need a varied diet:
Staple: High-quality flake or pellet food.
Supplements: Frozen or live foods (brine shrimp, daphnia, bloodworms).
Veggies: Blanched spinach, zucchini, or spirulina flakes for fiber.
Feed 1–2 times per day; only what they can consume in 2 minutes.
👨‍👩‍👧‍👦 Behavior & Tank Mates
Peaceful but active; males can be territorial with each other.
Ideal in a ratio of 1 male to 2–3 females to reduce harassment.
Good tank mates:
Mollies
Platies
Guppies
Corydoras
Tetras (non-nippy species)
Gouramis (peaceful types)
Avoid aggressive or fin-nipping species.
🐣 Breeding
Swordtails are livebearers — they give birth to free-swimming fry.
Gestation: 4–6 weeks.
Signs of pregnancy: Enlarged belly, dark gravid spot near anal fin.
Fry care:
Use a breeding box or separate tank.
Feed fry crushed flakes, baby brine shrimp, or specialized fry food.
Adults may eat fry, so provide hiding spots (like floating plants).
⚠️ Common Health Issues
Ich (white spot disease): Treat with temperature adjustment and medication.
Fin rot, fungal infections: Caused by poor water conditions — keep tank clean!
Swim bladder disorder: Often from poor diet or overfeeding.
👉 Quarantine new fish and plants before adding to your tank.
👍 Tips for Success
Keep a consistent maintenance routine.
Don’t overstock the tank.
Introduce fish gradually to prevent stress.
