In short: 8 to 12 cm as an adult including the sword, 100 L minimum, water between 22 and 26 °C. A sprinting swimmer, sometimes quarrelsome between males, it needs a long swimming lane and a single male or a female majority. An outstanding jumper needing a full lid and a tank at least 80 cm long, in moderately hard, well-oxygenated water.
Feeding a Swordtail: diet and habits
The Swordtail is an omnivore: a quality staple (flakes or granules) varied with frozen foods and greens. Its table is in midwater: offer slow-sinking food, dosed to vanish within two minutes — the surplus only feeds nitrates.
Frequency and variety
Feed little and often — one or two small servings a day — and grant a weekly fast without guilt: excess, never shortage, is what ruins tanks. In a group of 4 or more, check everyone reaches the food: dominants serve themselves first. Alternate dry, frozen and rinsed thawed prey across the week.
The costly mistakes
The Swordtail “begging” at the glass is not starving — it has simply learnt your silhouette: hold the two-minute line. Bottom-shelf food disintegrates before it is eaten and loads the water; the price gap to a reliable brand is measured in euros per year. The rest of the profile is on the full Swordtail profile.
