Hemianthus Callitrichoides is commonly known as Cuba. It is a very popular plant in aquascaping because of its ability to form a lush green carpet. Cuba is one of the smallest aquarium plants in the world and creeps over the bottom with millimeter sized round leaves. Trimming is required to achieve a uniformly dense carperted look. This plant requires high light levels to help it grow close to substrate. CO2 can also be helpful to speed growth. When a dense carpet is achieved, Hemianthus callitrichoides produces oxygen bubbles, known as “perling”. This looks very attractive when the bubbles are reflecting off the light source in the aquarium.
Tissue cultured plants are cultured in sterile environments. They are free of snails and disease pathogens. They have an extended shelf life and a perfect for aquascaping. These plants are small and have short roots so they can be challenging to plant. Gluing or using thread to attach portions to small pieces of rock, then submerging the rock in to the substrate works well.
