Dwarf Baby Tears Care: Carpet, Growth Rate, Temperature & Substrate

Dwarf Baby Tears Care: Carpet, Growth Rate, Temperature & Substrate

Dwarf baby tears (known as Hemianthus Callitrichoides or ‘ HC Cuba’) are by far the most elegant carpeting plant in my opinion. Given the right care and the right conditions, this plant will thrive and slowly cover any exposed substrate in your aquarium.

Tank Requirements

Temperature68-78° Fahrenheit
KH0-10
pH5.0-7.5
LightHigh (10 to 14 hours a day)
SupplementsCo2 and Fertilizer

Dwarf baby tears growth rate

Once planted, each portion will produce runners which basically are individual stems that branch off and grow along the substrate. In order to promote carpeting, high light is very important with this plant. Dwarf baby tears light requirements is at-least 2 light fixtures on your tank or growing this plant in a short aquarium, where it sits close to the light fixture, is best to provide adequate lighting for this plant.

Co2 is a must as well. I tried growing this plant under high light and nutrients only, and it grew but not very well. it’s already a slow grower, so not providing Co2 to this plant made it grow even slower. So high light and Co2 are a must.

Baby tears plant substrate and nutrient

I would say that dosing nutrients is optional, given I’ve grown this baby tears plant with high light and co2 only for almost two years, and I’ve grown a full carpet of it, but my substrate definitely played a role in this successful growth.

So I’d recommend a nutrient-rich substrate for this plant as well if you decide to not dose any nutrients.

Dwarf baby tears water temperature

Baby dwarf tears are very sensitive to temperature. Grow this plant in a tank that maintains a constant temperature of 78 degrees and below. Anything over that will just make this plant melt.

As far as compatibility, I found dwarf baby tears to be a very very hardy plant, compatible with most fish that I would deem not suitable for a planted tank. Even nippy fish can’t harm this plant, once it’s established. However, large fish of course like goldfish and cichlids will just tear this plant apart, so don’t house them with those fish. I learned that the hard way… I’ve grown dwarf baby tears with siamese algae eater, and no matter how hard they tried, they could not pick out it enough to ruin it or even remove a leaf.

So nippy fish will be perfectly fine being housed with this plant, but don’t get crazy with cichlids or goldfish because they’ll just turn it into one expensive salad.

Can I grow dwarf baby tears without co2?

In my experience, Hemianthus callitrichoides need CO2 to thrive. I tried to grow this plant with flourish excel, but the growth rate was very slow.

Fertilizer and plants color

Let’s move on to color, Dwarf baby tears normally will appear lighter dark green in color, but if your tank is lacking vital nutrients like iron and potassium, it may turn a white or yellowish color. And you know like I said, that’s a sign that your tank is lacking nutrients. You might want to consider either dosing iron or potassium or nutrients in general or grow the plant in a nutrient-rich substrate. Because if not, you can expect a lot of discoloration like I said and sometimes the plant will even just melt away. In order to maintain that nice bright green or dark green color, make sure you give it plenty of nutrients.

Propagation and reproduction

Let’s move on to propagation, once dwarf baby tears establishing your aquarium, simply cut small sections out of the original portion and replant them. yes, it’s pretty much that easy. Replanting individual stems, however, isn’t necessary and can be time-consuming. So removing small portions and replanting them is best. Just make sure each section you replant, has white roots attached to it and plenty of them. If not, that small section on the plant will just melt away.

Carpet plant trimming

Now, when it comes time to trim this plant, it’s not as difficult as it may seem. I would suggest however a good sharp pair of scissors to make good even cuts instead of ripping this plant apart with dull scissors. When you trim this plant, go slowly and only take a tiny bit off the top layer of the carpet. If you start seeing white roots with every cut, you’ve gone too far, this will only make these deep cuts melt away leaving holes in your carpet. So just be careful, go slow and just snip a small layer off the top.

When it grows back, it will likely appear thicker and fuller as well. But with dwarf baby tears, is already being a compact grower it may be hard to notice nonetheless it’s extremely fun trimming this plan in my opinion.

Dry Start Method

For those of you who don’t know what is the dry start method, is where you scape the tank, put in the substrate, put in the hardscape and then plant the plant without water.

Most people use the DSM (Dry Start Method) with a carpet plant. So you just plant the carpet, spread it very well and you put a clear film on top. You have to keep it like this for a period of 4-6 weeks. Then you need to give it a daily spray, and you open it so they get some fresh air inside, and what happens it’s like in a nursery. It’s in very high humidity, the plants growing, no water changes and no algae.

When you have a full dwarf baby tears carpet, you fill the tank with water and the tank looks good immediately from day one. But then you have again to make a cycle, because the biology is not yet there, and the filter is not running.

Conclusion

so in conclusion, I think dwarf baby tears are a great carpeting plant, by far the most sought after, the most requested and I think just the most beautiful carpeting plant.

They do however require Co2, nutrients and high light. Which means they are more for the advanced supporters or somebody that has a lot of money to invest in a plant tank. So maybe not the best beginner plant, or even intermediate plant, but more for the advanced aquarist, I think. So I think dwarf baby tears are great for anybody, but you just got to make sure you give them those 3 things, high light, Co2, and nutrients.
