Buenos Aires Tetra
The Buenos Aires Tetra is one of the hardiest of the commonly available tropical fish but it may not make a good choice for a community tank or a live plant tank. The Buenos Aires Tetra will view your live plants as a food source and will nibble at them. Since it's best to keep them in small schools they can quickly destroy your live plant collection, so plastic plants are the way to go with this fish. The Buenos Aires is a larger tetra, growing sometimes up to 3 inches (8 cm) and if kept in good water conditions can live 3 to 5 years or more. If you are planning on keeping them in a community tank caution is advised. They can be fin nippers and may bully smaller tetras and slower tank mates. Keep them in schools of 6 or more which should help direct their aggression towards the other tetras instead of their more peaceful tank members.
