Add the Fish

One of the most exciting parts of building an aquarium is adding fish to it! Before introducing new fish, it is important to ensure that the water quality is suitable for them to thrive in. You should test the water for pH levels, ammonia, nitrates, and nitrites. Once the water quality is satisfactory, you can start by adding a few fish at a time.

Be careful not to add too many at once as this can result in high levels of ammonia and nitrite, which can be harmful to fish. When choosing the type of fish to add, take note of their size, behavior, and compatibility with other fish species. It is also important to make sure your aquarium is not overcrowded.

Adding new fish to your aquarium can be an exciting experience, just be sure to do it carefully and responsibly.
