Hemianthus callitrichoides ‘Cuba’ Tissue Culture by Tropica
Hemianthus callitrichoides is one of the smallest aquarium plants in the world, creeping over the bottom with millimetre-sized, round leaves. It is an attractive and popular foreground plant for small aquariums.
This plant is not difficult to care for, but requires good conditions such as sufficient light, added CO2, water circulation, and regular fertilization to thrive. If these conditions are hard to maintain, Micranthemum ‘Monte-Carlo’ is a suitable alternative due to its lower demands.
Small pearls or bubbles of oxygen are often seen on top of the plants, adding a lively and dynamic appearance to the aquarium carpet.
When planted in small clumps spaced a few centimetres apart, it spreads rapidly and forms a dense, carpet-like coverage on the substrate. Regular trimming helps maintain the desired shape and prevents overgrowth.

FAQ
What are the light requirements for Hemianthus callitrichoides ‘Cuba’?
This plant requires high light intensity to thrive. It should be placed in an area with strong, consistent lighting, ideally 6–8 hours per day.
Can this plant grow well without CO2?
While possible in low-demand setups, Hemianthus callitrichoides grows best with added CO2. Without CO2, growth will be slow and the plant may not reach its full potential.
How should I maintain the plant to prevent overgrowth?
Plant in small clumps spaced a few centimetres apart. Trim the carpet regularly to maintain shape and prevent it from spreading too densely.

I planted this in a 10-gallon tank with high light and CO2. The plant spreads quickly and creates a beautiful carpet effect. The tiny leaves are very noticeable and the oxygen bubbles add a lively touch. I trim it every two weeks to keep it neat.

Grew well in my nano tank with good lighting and aeration. The plant is delicate and needs consistent care. I had to adjust the fertilizer schedule to avoid yellowing leaves. Overall, it’s a great foreground option.

The ‘Cuba’ variety is more compact than other Hemianthus types. It forms a dense carpet in a few weeks. I love the oxygen bubbles that appear on top—adds a natural, dynamic look to the tank.

It grows slowly without CO2. I had to increase lighting and add CO2 to see noticeable growth. Not ideal for beginners who can’t maintain stable conditions.
