Acquired: Fish / pet store
Posted Sep 30, 2014
The Swordtail wouldn't be my first choice of fish in my aquarium due to several reasons. Firstly, I had no idea that the females easily bred up to 80 fry at one time. They began breeding at 3-5 months of age. Due to this, many of them fell to predation by the adults. I had to buy another tank to separate the males from the femals to bypass overpopulation in the tank. However, I also noticed that the males don't deal well with one another as they could be quite territorial. Secondly, the Swordtails are jumpers! I'd advise those who purchase some Swordtail fish to make sure a proper cover is secured over the fish tank, otherwise some of these might meet their demise should they manage to jump out of the tank. Thirdly, it is said that the average lifespan of these fish is 2-3 years, yet my Swordtail started dying a year after they were bought at 2 months of age. That's when I decided to take them back to a pet store to ensure that they were given the best care possible. On a positive note, the Swordtail are nice to look at in the aquarium. Their colors are diverse and the length of their tails differ among the two genders, with the males having a greater length. Other than that observation, I wouldn't recommend purchasing Swordtail for one's aquarium unless a person has knowledge of what to expect and how to deal with this type of fish.
