The genus Rasbora is one of the most popular fish in small nano tanks. They are beautiful, small, and peaceful, making them a great addition to many small tanks. This fish prefers to live in groups, and a group of rasboras will make almost any tank more special.

Rasboras are quite tolerant, meaning they can be housed alongside many other fish. Because there are many rasbora types, there will certainly be one that fits your preferences.

However, they can also be quite fragile to water parameters, and as they are small, you might not notice a problem immediately. This makes it very important to research the species and to provide them with the proper care they need.
