Tetras are omnivores, like most species of fish. Oftentimes goldfish systems have a hard enough time cleaning the water with just a goldfish, it would not be a good idea to add other types of fish to put extra strain on these systems. While goldfish may not be aggressive, they are very dirty. Surprisingly, goldfish make poor tank mates for tetras. Larger tetras tend to do well with all of the above listed species as well as 'sharks' (balas and rainbows), gouramis and betas, swordtails, and some of the more docile species of angelfish.These little fish get along great with the above listed fishes as well as loaches, cherry barbs, and rasboras.


Smaller tetras, around one inch or less fully grown, tend to be more timid and get along better with smaller fish that are closer to their size.Mollies, guppies, cory cats, plecos, and danios are all popular tank mates for tetras.Tetras tend to be schooling fish and often do well with other kinds of tetras.Neon tetras are one of the few species of fish that nearly all fish keepers agree can be safely housed with bettas. They will also break-up the monotony of the tank. Live or fake plants will give these guys places to explore and hide. These guys come from tropical plant-filled waters. However, they also like a tank that has a bit of decoration in it. Some even think that a little salt will make your fish's colors brighter. However, it is recommended to add a little bit of aquarium salt to your tank in order to prevent diseases. Since these fish are freshwater you do not have to worry about the salinity of your tank. As these guys are tropical fish they need warmer water: a temperature somewhere between 74 and 82 degrees Fahrenheit is recommended. A pH between 6.0 and 7.8 is acceptable for most tetras. Most tetras do well in a range of water quality. Whatever size tank you choose just make sure that it as adequate filtration and that you clean and change your filters as needed. A group of six individuals makes a nice school, but if your tank allows for more fish I would have more. I think it adds something to my systems and makes them seem more natural. Personally, I like how tetras school in a tank. The larger the tank, the more fish you can have. They aren't overly large, making them more manageable, and they still allow for many different species of fish. 20 and 30 gallon tanks tend to be the most popular among hobbyists. Tetras do will well in tanks as small as five gallons to the largest tanks imaginable.
