The newest glo-Tetra did fin-nip the remaining Danio to death. As I was transitioning to the bigger tank, I had ended up with 5 glo-Tetra (gmo blackskirts) and 1 glo- Danio left over from my original tank. Males typically entice females into thick plant growth, where eggs are deposited and fertilized and hatch in a few days.I have regular finned black skirts. Tetras are egg layers, but extra effort is required to separate the adults from the eggs after spawning as many tetras will eat their own eggs. Tetras can be bred in captivity, but it can be difficult to create the correct environment to propagate and raise fry. For best results, rotate their diet daily and feed only what they can consume in under 2 minutes, once or twice a day. Frozen and live foods can also be fed as treats or to help induce spawning. Most tetras are omnivorous and will thrive on Aqueon Tropical Flakes, Color Flakes, Tropical Granules and Shrimp Pellets. Always consult an aquarium expert before buying any new fish for your aquarium. Good tank mates for tetras include other tetra species, rasboras, small danios, peaceful barbs, appropriately sized rainbowfish and livebearers. Others, like Buenos Aires tetras get quite large and are very active, which may intimidate smaller, more timid fish.

Serpae tetras, for example, can sometimes be nippy, especially when kept in insufficient numbers. Most tetras are peaceful and get along well with similarly sized community fish, but there are a few exceptions. Keep a secure lid on the aquarium to prevent them from jumping out if they feel scared or threatened. Dark substrates and decorations will help accent the bright colors of your tetras. They do best in schools of 6 or more and will be less stressed and show their best colors in a well-decorated aquarium.

Most tetras can be kept in aquariums of 10 to 20 gallons, but larger tanks are easier to take care of and give them more room to swim. Do not forget to treat tap water with Aqueon Water Conditioner before refilling your tank! Housing Requirements for Tetras Maintain good filtration and change 10% of the water every week or 25% every 2 weeks using an Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner. Exceptions like the Buenos Aires tetra do better in cooler water. If the aquarium is kept in rooms below 75°, use an Aqueon Aquarium Heater to maintain the correct temperature. For most tetras, pH should be between 6.8 and 7.8, alkalinity between 3° and 8° dkH (50 ppm to 140 ppm) and temperature between 75° and 80° F. While most tetras are found in soft, acidic water in the wild, the majority of aquarium species sold today are raised commercially in water that often has a higher pH and alkalinity than their native environments. They mostly inhabit rivers and streams, although one unique species, the blind cave tetra, was discovered in a cave system in Mexico! Tetras Water Requirements Tetras are found in the Americas and Africa, with the vast majority coming from the Amazon Basin and other river systems of South America. Selectively bred color variants and long-finned strains of certain tetras are also available. Others, like cardinals, emperors and penguin tetras are more challenging to keep and do best in well-established aquariums with softer, more acidic water. Popular beginner tetras include red eye, black skirt, serpae and bloodfins, but neons, black neons, glowlights and lemon tetras can be good choices as well. They are calm, colorful and mostly peaceful, making them ideal for both beginner and advanced hobbyists. Tetras are schooling fish from the family Characidae.
