Rocky rivers and streams in Cuba, Puerto Rico, and Jamaica are the original habitats of Dwarf Baby Tears or Hemianthus Callitrichoides. Thankfully, they’ve adapted to life in captivity, so many aquariums can reap the advantages of growing them.

They’re one of the tiniest aquarium plants, growing to about 1.2 inches, with exceptional bright green coloring combined with a soft creamy color of their roots.

The leaves of the plant are only about a millimeter and are oval-round shaped. They also feature long spindly roots that help propagate the carpeting foreground for tanks, as the roots stay anchored in the substrate, absorbing essential nutrients. 

But what’s truly magnificent about this plant is its unique feature of producing tiny bubbles of oxygen that resemble pearls that sit on top of the plant, giving the plant a very magical appearance.

Caring & Growing Dwarf Baby Tears

The below care guidelines ensure that you select the suitable methods for looking after your plant, allowing it to blossom with health and longevity.

Tank Requirements

For these beautiful greens to thrive and blossom, a minimum tank size of at least 10 gallons is best.

Water Parameters

The water parameters below are guidelines for what conditions the Dwarf Baby Tears enjoy.

  • Temperature: Maintain a temperature between the ranges of 68 – 75° F in your tank. This small plant tends to be sensitive to temperature, so you mustn’t overlook this factor. 
  • pH: Dwarf Baby Tears plant enjoys a pH level between 6.0 – 7.5. 
  • kH: Secure the water hardness to be between 1 – 10 dGH.
  • Hardness: This plant enjoys relatively soft water. 

Lighting Conditions

Dwarf Baby Tears are photophilic, which means they can’t sustain growth in dark lighting. Thus you’ll need to provide medium to high lighting, 10-12 hours daily, for this plant to grow healthily.

If you don’t have adequate natural lighting, you can use LED lighting of 40 to 50 PAR. Since Dwarf Baby Tears lie close to the substrate, the light will need to be powerful enough to reach it. 

Substrate and Fertilizers

Dwarf Baby Tears have a weak root anchorage and can take time to root well into the substrate. Thus, when selecting your substrate, look out for porous, small-grained, lightweight substrates as these work better for plants with weak rooting systems.

Opt for nutrient-rich soils such as the Amazonia Aqua Soil or powder. These two have refined grains that help the plant’s roots anchor quickly, enabling faster growth and substrate anchorage.

Dwarf Baby Tears require CO2 injections to maintain healthy growth. It isn’t easy to grow thick carpets and sustain them for long durations of time without using some fertilizer or CO2. You will require about 10-3 mg/l of CO2 and some iron supplements every time you notice the stems of the plant pointing upwards or the leaves turning smaller.

You can use fertilizers like Flourish Excel to speed up growth and supplement with some iron if the plant leaves and shoots start turning yellow. 

Maintenance

You can maintain the plant’s growth by supplementing it every now and then with CO2 injections, fertilizers, and iron to prevent weakened roots and stagnant growth. 

How to Plant Dwarf Baby Tears

These greens take time to grow; once they acclimatize to the tank conditions and lighting, they will start budding. Take small bunches of Dwarf Baby Tears and spread them across the tank’s bottom. Ensure that the roots are deeply embedded in the substrate to stop them from floating away.  

How to Propagate Dwarf Baby Tears

As slow growers, you can give Dwarf Baby Tears a headstart to creating a carpet through propagation. These plants reproduce by releasing shoots from their roots that form a whole new plant. These shoots can be gently cut and placed into another part of the tank to help speed up the carpeted growth.

Tank Mates for Dwarf Baby Tears

Dwarf Baby Tears require high-intensity lighting, so pair them with plants such as Rotala Macrandra, Christmas Moss, and Eleocharis Montevidensis that also require this. 

Freshwater, peaceful fish such as Cichlids and Tetras would be perfect tank mates for Dwarf Baby Tears.

Larger, ravaging fish such as Oscars or Jack Dempseys may nip at the plant and damage its integrity.
