Another terrific first-time fish is the Swordtail. I have owned dozens of them over the years and at one time, in a large tank I had over 30 of them. These are bright, active mid-tank dwellers that really perk up a tank with their colors and active swimming. They are hardy and can be used as starter fish for new aquariums.
The Swordtail is called so because the males of the species have a long sword-like caudal fin in the tail. The Swordtail species is a live-bearer and is a prodigious breeder, even in captivity. If you add several to a tank, you will get breeding if the water quality is good. Also, the males can get a bit territorial, especially around mature females – nothing to worry about but something to be aware of if you put them in a community tank with smaller mid-tank dwellers such as Neon Tetras. Swordtails require only the standard tank maintenance to keep them healthy. Please note that some might jump out of your tank during maintenance.
I highly recommend the Swordtail as starter fish or as an addition to any community tank!
