Aquarium carpet plants are a favorite among people who love decorating fish tanks. These plants grow low to the ground and spread out across the bottom of the tank, making a beautiful green carpet. They not only make your tank look nicer but also offer many benefits to the aquatic environment. This guide will cover everything you need to know about aquarium carpet plants, including how to choose the right ones and how to take care of them.
Introduction to Aquarium Carpet Plants
Aquarium carpet plants are aquatic plants that spread out horizontally across the bottom of the tank. Unlike taller plants that grow towards the water’s surface, carpet plants stay low and create a thick, grassy layer. This adds visual interest to your tank and provides a home for small fish and invertebrates, giving them places to hide and breed. To set up an aquarium with these green carpets, you need to understand the right water conditions, lighting, and supplements like fertilizers and CO2 for the best growth.
