When starting an aquarium, we want healthy plant life seen in these four signs. Without this healthy plant life, we may begin having trouble with our pH levels as well as the overall health of your fish. For the health of our fish and the overall appearance of our aquariums, healthy plants are a necessity.
How can you tell if aquarium plants are healthy? Four signs that aquarium plants are healthy include:
- Overall rich and colorful foliage
- Leaves with little to no holes
- Little to no yellowing of leaves
- No brown or black leaves
Determining if your plants are healthy is vital to your over-all aquarium health and beauty. There are many factors to take into consideration the signs and treatment of unhealthy plants. The types of plants you choose and how you keep them healthy, affect the overall care and appearance of your aquarium.
4 Signs of Healthy Aquarium Plants
1. Overall rich and colorful foliage
Just as with your outdoor plants and houseplants, a healthy aquarium plant will be green and lush and visibly thriving. It should grow evenly and regularly. (Not spindly.) It should look hardy and strong. (Not weak or brittle.)
2. Leaves with little to no holes
If your plants are developing holes, it is very likely a sign of rot. This could be from poor water quality, excess waste or insufficient nutrients. If your plants don’t have holes – take this as a good sign of healthy water and thriving plants!
3. Little to no yellowing of leaves
Most plant leaves are green. So, If the plants in your tank are beginning to yellow, this signifies there is a problem with the conditions in your tank. Most often, this can mean there is too little light. If it’s only the edges of your leaves are yellowing, it can mean there is a deficiency of some sort in the tank – very likely, too little potassium.
4. No brown or black leaves
If your leaves are nice and green, lush and vibrant, you’ve got some healthy plants. But if you notice leaves are browning or blackening, you may have an imbalance of nutrients in your water. Your water quality may be poor due to excess nitrates, too.
Common Reasons for Unhealthy Aquarium Plants
There are numerous reasons an aquarium plant is unhealthy and knowing the causes and what to look for are important to preventing these and, if needed, treating these plants.

6 Best Plants for Saltwater Tanks
The upkeep of saltwater aquariums sounds scary. You will always hear horror stories revolving around the time and energy needed to keep up the plants and fish inside.
This does not have to be true – there are ways to reduce the work and increase the enjoyment a saltwater tank brings to you and your environment. While most freshwater tanks are full of green plants that I admit look amazing, the plant choices available for a saltwater tank offer so many more color options to bring added life to the appearance of your tank.
The combination of the types of fish you desire in your plant and the care you dedicate to your aquarium will have a huge bearing on what plants you want to include in your fish tank. The needs and characteristics of each plant play a role too. If you have a plant that lowers one nutrient in your tank, and then you add a plant that requires more of the same nutrient, then one of the plants will not thrive.
You must also consider the temperature and lighting required for the plants, in combination with the lighting needs of the fish you add to your tank. This is where research and planning come into play. Below are only a few of the saltwater plants you can add to an aquarium successfully and are easy to root and sustain.
· Red Magrove Propagule
There are two ways that the Red Mangrove grow. They are either forming seeds or producing propagules. The seeds may not do well in tanks, but the propagule is stronger and more resilient. They grow to be as high as 8 inches and look much like a tall candle.
They should be planted in the sand or between rocks to ensure rooting holds quickly. This plant also lowers nitrate, which may require added care in your iron supplements.
These aquatic plants often referred to as the money plants, can be seen in almost any ocean worldwide and thrive in most environments. Their leaves look like oval coins that have been attached to each other by tape or glue.
With enough light and calcium, they do well but do not tolerate high nitrate environments very well. The fish will not nibble on these plants, and they are non-evasive making them perfect for an environment that supports other aquatic plants
· Dragons Tongue Algae
These plants offer one of those bright colors to the backdrop of your aquarium. They are bright orange and different texture to them with the benefits of improving the oxygen quality throughout the aquarium. Planting them next to or between rocks ensures the best results for their growth. Often the Dragon Tongue Algae are paired up with seahorses.
· Green Finger Algae
This type of algae is a lush and dense plant that is easy to care for. Herbivore fish are not interested in nibbling on these plants and are fish friendly to most aquatic life. This also helps supply oxygen to keep the tank clean and healthy.
· Red Gracilaria Algae
This is a prime example of the beautiful colored plants available to saltwater fish tanks. While the color alone may be an attractive reason to include this plant, the benefits are amazing, as well. The Red Gracilaria Algae promotes healthy nutrient levels and rid the environment of invasive algae.
These algae may also be harvested to be fed to fish as a food supply. To plant these Algae, its best to anchor them to a rock or other firm surface to promote stability.
· Turtle Grass Shoot
As an amazing plant capable of hypnotizing you because of the way it glides with movement within the tank, it is strong and offers new growth sprouting from the ends. The roots spread further than many aquarium plants a need a sand bottom at least six inches deep to grow.
Once it has established itself in the aquarium, fish such as seahorses, small fish, and invertebrates love to enjoy this plant.
6 Best Plants for Freshwater Aquariums
In addition to the appearance of a full eco-system, the beauty and sustainability supplied by plants are pleasing. Plantlife in an aquarium bring so many benefits to the fish within. Safety, comfort, and even food are amazing reasons to add plant life to your aquariums.
· Java Moss:
Though Java Moss is known for floating around a tank, this can be fixed by using an elastic band or something similar to attach it to driftwood or stone items in your aquarium until it is rooted. They are better suited for low light aquariums and thrive better in these conditions. The temperature endurance is between 70-90 degrees.
· Amazon Sword
This is one of the easiest maintainable plants for a freshwater aquarium. These large growing plants can of up to 20 inches survive in most conditions, but with the addition of nutrient supplements and high lighting, they can grow extremely fast. These are easy to care for and a cheap plant choice for beginners caring for or starting an aquarium.
· Java Fern
Like the Java Moss, this is the number one pick for shrimp. These require attachment to decorations or rocks to secure them, but this can be done in the same way the Java Moss does it with bands or tying them to secure them. They survive well in 68-82-degree temperatures in low to moderate lighting.
Even though it is a beautiful background decoration for your aquarium, it is also a nice hiding spot for your fish. The Java Fern is a simple to grow plant and discharges spores to attach to other areas in your tank and grow. These also do not require liquid fertilizer, which can be a relief for someone just learning.
· Anubias Nana
These are often sold already attached to driftwood or rocks, making securing them no worry. Because it is already attached to an object, you do not want to cover the bottom of the roots. This would be an ideal plant to be close to larger and taller plants because it requires more shade to prevent algae growth on its leaves. It does not require a lot of nutrients, so fluid fertilizer is not needed.
This plant is better suited for smaller aquariums. This is a larger expense when it comes to plants for your aquarium but an excellent choice for tanks that house fish who require hiding places.
· Crypt wendtii
In picking these plants, you must take into consideration they are less resistant to changes. Extreme changes can cause them to liquefy. They require a little more care in how much light they receive and are better suited for a little more experienced aquarium enthusiast.
They do add a nice overall look to the aquarium. They will appear to be dissolving when first being planted but this is their reaction to their adjustment to an unfamiliar environment. As its roots, it will return to full health.
These aquarium plants offer many sizes, shapes, and colors to choose from. They are a wonderful plant choice when shrimp live in your aquarium. The lighting is still dim being the best choice, but the root care is a little more complex. Covering the roots in a minimum of 2 inches of rock is needed while keeping the leaves above the rock.
Within the low lighting it should be set at moderate lighting in temperatures of 72-82 degrees. Like the Crypt Wedtii plants, they will appear to be dying when first planted. They will usually lose most of their leaves. This is not uncommon or lethal to the plants themselves.
Benefits to Your Fish in Having Aquarium Plants

One of the Most Pleasing Aquarium Plants to Look At
The Tiger Lotus is a beautiful addition to an aquarium. When your goal is to supply the most attractive looking aquarium, the Red Tiger Lotus is among one of the favorites. Colors and shapes of aquarium plants are the main consideration in trying to make your aquarium look its best. The Red Tiger Lotus has broad red leaves, adding a pop of color to your aquarium.

Hi, my name is Adam and I’m an aquarium enthusiast! I didn’t discover the joys of being an ‘aquarium fanatic’ (as some of my friends call me!) until I was in my 20’s. When I first started out I found it difficult to find all the information I needed so I started this website to compile all the useful information I can think of. Enjoy!
