Planting and maintenance

How to plant and maintain the Fish grass?

Plant requiring a lot of light. To do this, count a lighting power of between 1 watt for 1 liter or 0.3 gallons of water and 1 watt for 3 liters or 0.8 gallons of water. Under suitable lighting, your Cabomba caroliniana will grow very quickly. It will grow so fast that you have to prune it almost every week.

Plan an aquarium of a good height, because it grows quickly and can become very large, sometimes exceeding 1 meter or 40 inches.

Be careful that the light reaches the entire plant. Otherwise, its leaves will start to fall, which will not be pretty. It will be important not to have too close plant that would shade the foot of the Cabomba.

The plant is so invasive and dense that in streams it prevents light from reaching the plants at the bottom of the river. It is also a danger for the fish below.

It could also endanger children swimming near it. Indeed, they can get stuck in the stems and risk drowning.

Finally, this plant can even degrade drinking water supplies.
