Ideally, install this plant in the background as it tends to spread and will cover your soil.

In good health, it forms a dense and continuous bush that will be a refuge appreciated by all fry, but also by all shy and fearful fish.

The Sagittaria will appreciate being planted in rich nutritious soil from which it will draw the necessary nutrients for its growth. When these substances begin to be lacking and the soil becomes impoverished, the plant will suffer from chlorosis (weakening and yellowing of the leaves). It's time to put fertilizer at its feet! Also remove damaged leaves.
