Tetras are the perfect beginner fish. They are bright, colorful and very active, so they’re a lot of fun to watch. They’re also small, which means you can have several, even if you have a smaller tank. This is good, because tetras do well in schools of at least three to five fish. Fish Tank Kings star and aquatic development manager at Rolf C. Hagen, Francis Yupangco, says tetras can live peacefully with various types of tetras as well as other community fish. They do require a full tank setup, including a heater and filter, but that’s something you’ll encounter with any tropical fish. Tetras also love heavily-planted tanks, which means you get to have fun picking out lots of those pretty, colorful aquarium plants.
