    • Description

      Hemianthus callitrichoides (HC Cuba) is one of the most magnificent aquarium plants. With millimeter size leaves, dense growth and a vibrant green color, it breathes life into any aquascape. With bright light and carbon dioxide, it grows as a short, dense, creeping carpet. HC can also be grown as an epiphyte on driftwood for unique creations such as "bonsai trees". It is extremely flexible and can be used to great effect in the smallest nano aquariums to the largest display tanks and is especially stunning with shrimp and small, brightly colored fish.

      Though it really shines in ‘high tech’ setups where it grows into a vast, pearling lawn of green. HC can also be grown as a normal, albiet tiny stem plant in low tech tanks, bowls and nano-aquariums. Due to its diminutive scale, it can make small aquascapes appear huge and huge aquascapes appear colossal. 

      To accommodate its small dense roots, we recommend a fine substrate. Plant in small clumps just a few centimeters apart. When acclimated, H. callitrichoides will grow quickly, and these small clumps will grow into each other, spreading over surprisingly large areas and carpeting the exposed substrate of your tank. Occasional trimming is recommended to tame vertical growth and may be used to intentionally shape the terrain and even creating terrace-like effects.

      While nutrient supplementation is not required, a fertile substrate will encourage healthy growth. The accumulation of detritus could choke this plant, so we the occasional gentle vaccuming during water changes. 

      Herbivorous or digging fish will uproot and damage H. callitrichoides, shrimp will not. In fact, we recommend the addition of shrimp to your tank as they will clean leaf detritus gently, maintaining aquascape health and aesthetic. We also recommend a slightly acidic to neutral tank pH as hard alkaline waters can cause mineral deposits on the small, delicate leaves and slowing growth.

      HC is without a doubt one of the most rewarding aquarium plants. It has a je ne sais quoi that transforms a glass box with water into a slice of natural paradise. If you have an aquascape that feels like it's missing something, a carpet of HC is an almost magical way to make your aquarium look and feel complete.

      Though it can be grown without, for many people, HC alone, is a compelling reason to set up a CO2 system. If you already have CO2, this plant makes great use of your investment and should be seriously considered. A lush green lawn of HC is frequently considered the epitome of the planted aquarium - well worth the challenge! Given the right conditions you might be surprised at how easy it is to achieve...
