Foreground aquatic plants
These are the flora that is usually found at the front part of an aquarium. They are generally short and grow wider than higher. Some are named carpet plants since they spread on the ground like a carpet. Foreground plants take a long time to grow and fully cover the bottom side of the aquarium.
Examples of carpet plants are the Java Moss and the dwarf baby tears.
Mid-ground aquatic plants
These are the crops found after the foreground plants growing in the mid-section of the aquarium. Unlike the foreground plants, they grow vertically, and many can fit in a small area.
They are a bit taller and bushier thick enough to offer the fish and other aquatic animals a refuge to hide and breed. They can also be taking space at the edges of the tank as habitat.
Examples of these kinds are the Water Wisteria, the African Water Fern, the Amazon Sword, Java Fern, and the Dwarf aquarium lily.
Background aquatic plants
These are the plants that grow big with broad leaves and bushy foliage. They are usually very vegetative, and fish like using them for hiding when spooked. It is also the perfect location for fish to breed.
The plants mentioned in the mid-section could also be used as background plants, but others are like the Anubias and the Cryptocoryne Beckettii.
Why You Need Water Plants For Your Aquarium

They provide security and shelter
Sometimes the harsh bright lights in our homes and the constant movements can spook the fish and send them to hiding.
And where should they hide if they do not have any place to find refuge? Well, plants provide this fish and other aquatic animals in the tank a place to find security. These same plants could be used as breeding grounds, where the fish lay the eggs at the plants’ base.
