However, this should not cause any concerns because there are still thousands of fish to choose from. In this article, we will highlight some of the most popular fish for planted aquariums.

They are known for their interesting colors that cause reflections in the water and their unique character. Even though they are called dwarves they are actually large for standard planted aquariums. They are about two inches long, but there are examples of 3-inches long dwarf gourami. In any case, they should be kept in larger planted aquariums. Their blue and red color will bring contrast to the green planted aquarium and you should feel free to keep them with other species of fish because they are usually not aggressive.
This species of fish are livebearers and this is just one of the things that make them unique. Many people keep them because they are highly adaptable.

Harlequin tetras are another good example of great fish suitable for planted tanks. They come in small size and special reflective coloration. They usually don’t grow for more than one inch and live for ten years. Their sheen has an exotic rose color and they also have a dark line on their back in the form of the letter L.

They are easily recognizable due to their bright orange color and the small size which almost never exceed one inch in length. Even if you buy a few of them, your aquarium will still look large. Ember tetras usually swim in schools creating bright straight trails. They thrive in environments with low pH value.
In case you want to make your planted aquarium look more exotic, then you can’t go wrong with the Chili Rasbora. Just like most of the fish on this list, they are quite small and they have special red coloration that makes them more interesting.

Due to their size, they can make your tank look smaller.
Angel fish have been around for some time. From the moment they’ve become available to aquarium enthusiasts, they have become an instant hit.

There are some subspecies that are smaller.
