The Neon Swordtail is a live-bearing fish related to freshwater aquarium favorites including guppies, mollies, and platys. As such, a female Neon Swordtail can give birth to as many as 80 fry at one time. A spawning box is recommended, or if one is not available, provide dense floating cover to protect the Swordtail fry from potential predation by the adults. Unless it is your intention to breed Neon Swordtails, the male Swordtail fry should be separated once the sex of the fry is determined. The Neon Swordtail can begin breeding as young as three months of age and can quickly overpopulate an aquarium.
Tropical Fish for Freshwater Aquariums: Neon Swordtail - Live Aquaria
With their bright neon blue coloration, neon tetras have been a favorite among fishkeepers for ages. With colors that rival marine fish, they are indeed one of the most beautiful freshwater species to keep. Only reaching one inch in length, they certainly are able to fit comfortably into most beginner's tanks. Why then are they not a good beginner fish? First of all, they do not adapt very well to changes in their environment. This leads to many difficulties when you bring the fish home. It is not enough to just float the bag in the water for ten minutes and then set them free. They need to adjust much more gradually by adding small amounts of aquarium water in the bag over a long period of time and then releasing them into the aquarium. Even then, they can still be very nervous and go into shock easily. They also require very clean water to do well in the home aquaria. Frequent water changes are a must to keep from having your neons start dying for no apparent reason. Their sensitivity does not make them very forgiving of mistakes that are bound to be made when a person first starts out.
