Las 30 mejores plantas de acuario que pueden crecer sin sustrato

1. Planta de acuario Hornwort: la mejor en general

Hornwort
Acuáticos o Anfibios:: Anfibio
Nivel de atención: Fácil

Hornwort is an excellent plant for beginners that doesn’t have too many care needs. That’s why we chose it as our best overall aquarium plant that doesn’t need substrate. Hornwort is usually found floating on top of the water in the wild, and you can do the same in your home tank.

However, hornwort can be planted in the substrate and grown as a submerged plant in aquariums; if you ever decide to build a tank that does use a plant-friendly substrate, you can take some of your hornwort plants and plant them in your new tank as well.

Hornwort grows pretty fast, a feature usually seen as a downside in the wild. But in the aquarium world, this lovely plant will quickly beautify the tank with its presence. Hornwort will also provide a little bit of shade to your tank since it floats on top of the water!

  • Can be planted or floating
  • Easy to care for
  • May overgrow because of the fast growth rate

2. Java Moss — Best Value

Care Level: Moderate

Java moss is an excellent option for pet parents looking for a submerged plant that doesn’t require substrate. Java moss will attach itself to rocks and driftwood in your tank rather than needing to be planted in the substrate. You can also buy it in bulk, so we chose it as the best aquarium plant that doesn’t need substrate for the money.

Java moss doesn’t just look lovely in your tank; it’s also beneficial to your fish. For example, Java moss makes a fantastic meal for newly formed fry (very young fish.) Fry are often hard for owners to feed because they aren’t as powerful as the other fish and can get bullied away from food.

Luckily, Java moss can be an excellent food source for them. Java moss will also provide much-needed shelter from the sun since moss that doesn’t attach to rocks or driftwood will float on top of the water.

  • Never needs to be planted in the substrate
  • Provides good food for fry
  • Not suitable for cold-water tanks

3. Anubias Nana Aquarium Plant — Best Premium

Once connected to a piece of driftwood, it grows on its own with very little intervention from humans, making it a great addition to a beginner or experienced aquarium.

It’s a tough plant that can withstand many conditions and algae-eating fish that may attach themselves to its leaves. It can even handle a lot of plant-eating fish that might look at it as a tasty snack.

Buyer’s Guide: Choosing the Best Aquarium Plants that Can Grow Without Substrate

When buying aquarium plants, you want to ensure that your fish and plants will be compatible. Both fish and plants are alive and have care needs that must be considered when housing them together. Research the plants and fish you intend to keep thoroughly to ensure compatibility.

When building an aquarium, you create a closed ecosystem filled with plants and animals. This means that all the ecosystem members must function within the ecosystem to provide for themselves and each other.

In a water ecosystem, plants provide oxygen to the water, and fish provide carbon dioxide. The fish and plants have unique needs but provide for each other. So, it’s essential to ensure that the members of your ecosystem can thrive together and won’t hurt each other.

Temperature

Plants grow at different temperatures, and each plant has different temperature needs. Keeping plants at the wrong temperatures will stunt their growth or even kill them. This is true of fish as well. So, you must know what temperature your ecosystem will be kept at.

For instance, Clown Killifish can be kept in a cold-water tank without a heater, but Rotala indica requires a warm-water tank that stays at a temperature of at least 72°F. So if you have a cold-water tank with no heater, you can’t keep Rotala indica in it.

Water Hardness

“Water hardness” refers to the mineral content dissolved in water. Some plants can tolerate hard water, while others will wilt. This is true of fish as well. You can’t keep plants and fish that require soft water in hard water and vice versa. Ensure that your water is appropriately hard or soft for your ecosystem to thrive.

pH Balance

Different plants and fish also have different acidity needs for their environments. Some plants need to be kept in an acidic environment, while others thrive in an alkaline environment. Ensure that your plants have compatible pH needs.

Light Requirements

You also want to make sure that you buy plants with compatible light requirements. While all plants need light, they need different amounts. In addition, some plants can be damaged by receiving too much light. So, you’ll want to make sure that you can provide the correct amount of light without providing too much.

Minimum Tank Size

Plants also have minimum space requirements to grow and thrive. They are living creatures that require space to live. Therefore, you want to ensure that your plants are in a big enough tank for themselves and in conjunction with the other plants you have in your tank.

Fish Compatibility

It’s also essential for your fish to be compatible with your plants. While most fish owners will feed their fish daily, some fish will eat the plants in the tank. Many plants will be able to thrive even if there are aggressive fish, plant-eaters, or algae-eating fish that may attach to them. However, some plants are more delicate and will wilt. Ensure that your tank has a thriving ecosystem by choosing compatible fish and plants.

Substrate Needs

While this list focuses on plants that don’t require a substrate to be planted in, buying plants means ensuring that they will be able to thrive in your tank. While you may leave plants floating in your tank, some of those floating plants could later be planted in your tank’s substrate. Therefore, ensure that your substrate is suitable for the plants you want to buy before you buy them.
