There are many freshwater species that you can keep in your tank, but few of them make a better choice for first-time aquarium keepers. Without further wait, let us get to learn about 10 best aquarium fishes that are a perfect choice for beginners.

Neon Tetras

Known for their blue bodies with bright red stripes, Neon Tetras are one of the most popular freshwater species. They are thin, small, and very easy to take care of.

Neon Tetras do not even grow too long and reach only about 2.2 cm in length. They are calm and peaceful by nature and do best when you keep them in groups and aquariums with plants, rocks, and other accessories that they can use to hide.

Mollies are easygoing and small and you will not have to do much to take care of them. They grow around 3-4 inches long and look quite attractive.

Mollies are omnivores and will thus eat other animals and plants as well. What is immensely attractive about these fishes is that they are livebearers. Their eggs develop in their bodies itself and come out as live fry.

Since these fishes love to breed, you must keep only one gender if you have a small tank and do not want too many of these fishes.


Wild male and female guppies (wikipedia).

Guppies too make a great choice for beginners. There are not fussy but they can breed with each other pretty fast if you do not keep the genders separately.

You can find Guppies in many colors, and the males look more attractive than females. These fishes have lively personalities and can easily adapt to many water conditions. This is in fact what makes them so popular among novice aquarists.


Goldfish Best Aquarium Fishes for Beginners

This is yet another extremely popular freshwater fish. They can grow nearly 14-inches long in the wild and 5-inches in aquariums and look very attractive. Some Goldfishes are even known to live for more than 25 years.

You need an aquarium of at least 20-gallons if you want to house these fishes. But since they are low maintenance you have nothing to worry about. All you have to do is use a good filter, and change water on a weekly basis.
