Can Baby Tears Grow Underwater?

The baby tear can grow well in the lower water level. But the problem occurs when we think of growing them in our tank. They can survive in the full-filled tank, but not longer. Therefore, you need to decrease the water level for some time. 

After every week, you need to change the water from the tank, and the floating leaves are to be collected out of the tank. Now our main question is can they live underwater? Yes, they can, but you need to drop the time level to the roots level every week. If you do not perform this, they might die inside the tank.

How To Plant Baby Tears Aquarium?

You do not need any hard course to grow dwarf baby tear plants as they are too easy to grow. You need to take healthy stems of baby tears and plant them like other plants. You need to take care that the roots are deeper because they must be under the substrate. 

If the roots are not deeper, the plant could float away. Once your plant is fully grown to spread, you can trim the stems from the plant to plant them everywhere on the substrate. Trim only those items which are healthy and more green.

Can Dwarf Baby Tears Grow On Rocks?

The dwarf baby tear is ideal for the foreground, and people use it as a mat in their tanks. However, you would be shocked after knowing that it can grow on hard surfaces like rock and wood. 

You can also use the rock as a substrate, or any other substrate can also be used, but this plant also prefers hard substrate. If you have stones in your tank, a dwarf baby tear will cover your stones also. Growing them on rocks could be time-consuming, but it is healthier for baby tears.

Tank Requirements

The Hemianthus Callitrichoides will thrive in mostly acidic water with a pH range between 5.0-7.5 and a temperature between 70-84 degrees Fahrenheit. Being so small, this plant is ideal even for Nano tanks, provided they are well-lit.

Light as strong as 2 watts per gallon minimum should be available to keep the plant growing close to the ground. Less light will cause it to rise up to the water’s surface, where it naturally lives in the wild.

Planting your Dwarf Baby Tears

Dwarf Baby Tears are usually found rooting on porous rocks or driftwood pieces. They can also be planted in the substrate as a foreground plant, but the effect is much stronger and natural when attached to other tank objects.

You can tie small sections of Hemianthus to a rock or wooden piece of your choice and leave it to develop its roots around the object. Most aquarists prefer using cotton thread instead of rubber bands or fishing lines, as it is hardly noticeable and it dissolves over time, leaving only the roots attached.

Another way of keeping them from floating around would be to cover the Dwarf Baby Tears’ roots with moss that will add some weight to the plant.

These mosses will provide extra nutrients, as well as a good hiding ground for newly hatched fry.

For planting in the substrate, you can plant a whole pot in one place and wait for it to spread, or you can separate small stems and plant them about one inch apart for faster coverage.

This is a time-consuming process, though, so allow some aquascaping hours. Plant the stems using a long pair of tweezers and make sure the roots are well inserted in the soil.

Care

Dwarf Baby Tears need a fine-grained substrate rich in nutrients and minerals, especially iron. The plant is sensitive to iron deficiency and will display yellowish leaves if there is not enough iron in the tank.

They will do best with CO2 supplementation and constant fertilization to help accelerate the growth rate.

Always prune this plant, as while growing, new stems will get on top of old ones and suffocate them; DBT literally kills itself if left unattended.

Trim the stems with a very sharp pair of scissors or a razor blade to help keep them in place while trimming.

Reproduction

The Hemianthus has pretty slow growth and development rate, but will still spread across the substrate after settling in your tank. Roots will branch off and develop an intricate network, resulting in a carpet-like appearance, but only if you remember to constantly trim the plant to keep it low.

Another popular method of propagating the Dwarf Baby Tears is to cut off smaller sections of larger plants and replant them in the substrate.

This way, they will cover up the tank floor faster, as propagation is made from many points.

Dwarf Baby Tears Compatibility and Tank Mates

The Dwarf Baby Tears can be planted alongside other short foreground plants in contrasting colors. The dense carpet will allow spawning fish to lay their eggs and the young fry to hide from harassing adults.

There is no worry if plant-nipping fish graze on the DBT, as they will quickly recover and grow again, especially if it has already covered a considerable surface.

Try not to add ravaging fish, such as Oscars or Jack Dempseys, to a tank planted with DBT, as they will try to uproot weaker stems when “rescaping” the tank.

Goldfish are not a good idea because of their different environmental requirements and because they will stubbornly try to eat as much of the plant as possible.

Be creative and use your imagination and try some aquascaping tricks with this small versatile plant. You can use it in many tanks, from the smallest to the largest, in a variety of ways.

Conclusion

In the end, we would only suggest that if you have experience in an aquarium setting, you can go with this plant and can use it as carpeting, but if you are a beginner, you should first get some experience.

  1. Thanks for this post! I purchased a mat of HC pre-rooted in coconut fibre for my CO-injected tank. It looked great for about 2-3 weeks, then I noticed that it was loosing leaves from the mat. Currently I have a whole mess of HC floating at the surface (it’s clearly reproducing), but the mat is nearly empty 🙁

    So any ideas what I might have done wrong? I use liquid fertiliser, although not as frequently as I should. I suspect that this isn’t the issue as the HC is growing – just on the *surface* of the water.

    Is there any reasonable way to re-plant the floating stuff?

    Tank details:
    36gal bowfront
    CO injection
    2x39W 6500K T5 lighting (~2.2 W/gal)

  2. I have a very healthy carpet and a large mass of DBT floating on the top for cover.

    I started the DBT from seeds. How do I get the current plants in my tank to start producing seeds?
