When setting up a tank, the most important thing to consider is to have enough room for the fish to swim in the tank.

I have seen most fish keepers fill a large number of decorative ornaments, and due to that, fish haven’t sufficient space to swim.

Since they are very fond of aquatic plants, you should be sure to provide a similar environment with aquatic plants in your tank.

You can use fish-friendly aquatics plants like Java moss, Java fern, Peat moss, Hornworts, etc. They can use it as hiding places.
