Guppies

• Guppies are lively, multi-colored fish that coexist peacefully with neon tetras. The females are usually less colorful than the males, but in some species of guppies, females also can have several colors. You must immediately separate newborn guppy fry from their parents, because the parents will eat them. It is best to have plenty of aquatic plants in which young guppies may hide, even after they are a little larger.
  
  

Discus

• Discus are attractive, highly-carnivorous fish that feature varied coloration, from vivid green and orange to sky blue. They appreciate clumps of dense plants, pieces of driftwood and areas of low light, such as those under floating vegetation. Since the fry feed on the mucus of their parents, the parents and fry must not be separated. Discus fish are peaceful members of their habitat, and will get along well with neon tetras.
  
  

Swordtails

• Neon tetras and swordtails are two freshwater fish that make good aquarium mates. The colors of swordtails vary from blood red to iridescent rainbow hues. These active fish are peaceful and easy to care for in a community aquarium. Despite their tranquil nature, two male swordtails in a tank may not get along. They also are high jumpers and need a secure cover on their aquarium.
  
  

Corydoras Catfish

• An adaptive aquarium habitat needs bottom feeders to aid in keeping the tank clean. Corydoras catfish seek out unused food on the bottom, using their whisker-like barbels. Native to South America, "corys" come in various colors, from white and black to bright orange. They are compatible with neon tetras, can live from 15 to 20 years and will be a welcome addition to your aquarium ecosystem.
