The Black Tetra is very popular in the aquarium hobby. It is also known as the Black Skirt Tetra, and Black Widow Tetra. They make a nice addition to any community style fish tank. Choose your tank mates wisely though, avoid keeping them with fin nippers like the Tiger Barb! They are a peaceful fish and get along with a lot of different types of tetra fish, but they can also be fin nippers themselves so avoid keeping them with fish like Bettas. Also, try to keep Black Tetras in a group of at least six or more to make them feel more comfortable.
This is a great beginner fish because they are not very demanding as far as water quality goes. You should start them out in at least a 20 gallon tank so you can get a nice school of them. You could probably fit about 15 Black Tetras in a 20 gallon tank. Make sure that your tank has cycled before adding fish! Check our Filtration page for more information.
