Swordtail Species: Key Points, Tips & Tricks - Swordtails Q/A
- Only male Swordtails have the "sword", while females have a rounder body. (See picture above. The female is on top in the center, the male is on the bottom in the center, with a swordtail)
- Very cool fish, the sword will grow on young swordtail males when they are about three quarters grown.
- Easy to keep and like mollies can tolerate slightly brackish conditions but whether they need them is debatable as all swordtails in shops will have been reared for generations in freshwater tanks.
- Their life expectancy is three to five years.
- Male swordtails need to be out numbered by the females in a ratio of at least two to one, otherwise your females will never get any rest! Males can also be very persistent toward females during mating.
- Swordtails are fairly peaceful but males can become aggressive toward each other.
- When they mate the male will swim backwards to get the attention of the female.
- Once the female is pregnant she will develop a black triangle area (gravid spot) behind the stomach.
- Females will carry their young for about 32 to 36 days and will give birth to as many as 150 fry!
