The 10 best aquarium plants for goldfish (that will survive)
When it comes to aquarium plants, Goldfish are not the first species you associate them with. Renowned for being messy, boisterous and hungry fish, Goldfish tend to be kept alongside fake aquarium plants or in a bare bottom tank. You would be forgiven for thinking goldfish cannot be kept in anything else. Well, we aim to show you that this is simply not the case. In this article, you will discover the best plants for goldfish aquariums. Plants that are easy to care for, look good but most of all, capable of withstanding everything that a goldfish tank can through at them.
What is so challenging about a planted goldfish tank?
First of all, to understand the challenge of growing live plants in a goldfish tank, you need to learn a little about goldfish themselves. Goldfish (Carassius auratus) have been domesticated for around 3000 years and have been selectively bred, providing us with multiple varieties which is why they have become so popular. As part of the carp family, they can grow quite big and being social fish, the need for a large aquarium is a priority for anyone looking to correctly set up a goldfish aquarium.
Like all larger fish species, Goldfish create a lot of mess and as such, good filtration must be included in any goldfish keepers aquarium setup. Without adequate filtration, goldfish waste will build up and cause issues with the water quality.
During feeding time, Goldfish will take food from all levels of the aquarium. It is during feeding time that the aquarium and its decor receives the most damage. Goldfish will rummage the substrate, move decorative wood or stones and even gulping down anything that remains on the surface. When you couple their hunger with their size, large amounts of fish waste and also the fact they should be kept in groups, it is quite clear to see why goldfish keepers find it difficult to maintain an attractive, planted, goldfish proof tank.
What have Goldfish keepers been doing all these years?
As mentioned earlier, Goldfish have been around for a very long time and through the years most goldfish keepers are focussed more on providing the best care for their beloved fish than making the aquarium itself look nice. Many plants and alternatives have been used through the years, some have worked, some not so much. Goldfish keepers have tried to find the best aquatic plant, capable of withstanding life in a goldfish aquarium. Below is some examples of what has not worked. How many have you tried?
The Stem Plant
A stem plant are a group of plants with similar features and as the name suggests, they are mainly stem based. The root systems on such plants are delicate and not robust in the slightest. These plants pull most of their nutrients directly from the water column via their many leaves meaning their roots are very small. Although Goldfish will not usually eat these plants, they can easily uproot plants with a root system as delicate as these do. If planted in a Goldfish tank, they will be damaged on a daily basis, resulting in broken and decaying plant matter all over the aquarium.
It might be the obvious choice for anyone who wants the aesthetic benefits of a planted goldfish tank but using fake plants does have drawbacks. We mentioned above that Goldfish love to uproot plants and this still applies to fake plants. These plants, wether plastic or silk plants, they still need to be placed into the substrate to remain in position. While feeding, Goldfish will rummage everywhere in search of their meal, resulting in the substrate being moved, including any fake plants.
Bare Bottom Tank
Yes, the name does sound a little funny but in fact, this style of aquarium is used by a wide variety of different aquarium keepers. There are huge benefits to having no substrate in your aquarium. The main benefit being the simplified cleaning procedure. Without substrate, fish waste tends to gather together in the area with least flow, making it easier to remove. This method is often combined with our next method.
Real Plants In Pots
It might be no surprise to keep plants in pots however, in an aquarium it is actually not usually the done thing. However, if you are a Goldfish keeper and wish to benefit from real plants, you may be interested to know, this has been a method used by fishkeepers for many years. It is more common among fish keepers with bare bottoms (now now). By adding the right plants to pots in the aquarium, it is less likely your goldfish will damage them. The only downside to this is that it doesn't look very natural.
A terrestrial plant is what we commonly know as a house plant. They are basically plants that grow above the surface of water, away from the edge of water. Generally terrestrial plants cannot survive underwater with only a few exceptions. One of the most common plant that has been used by goldfish keepers are Pothos plants.
A Pothos plant is a vine plant known for its art purifying ability that is often used in the aquarium hobby to greatly improve the aquarium water and appearance. This large plant can be positioned in such a way that the roots are in the aquarium but the leaves grow beyond the surface of the aquarium water. The pothos plant are heavy root feeders and with their extensive root system, can create a very appealing feature to an open top aquarium.
Marimo Moss balls
Moss balls are known for their ability to absorb nitrates in the aquarium. This is hugely beneficial in a goldfish tank due to their excessive production of fish waste. They also absorb other harmful substances in the fish tank and even provide a home for beneficial bacteria. Oh and we think they look pretty cute too. Recently, it has become popular to keep small groups of moss balls in bowls of water on their own. Kids love them, goldfish don't eat them either.
But what if you want to create a setup with aquatic plants using plant species that looks good?
Now you have an understanding of what the goldfish aquarium keeper has worked with over the years, you may ask 'what's new?' well the truth is, nothing much is new so to speak. Instead, a different way of thinking is required to create a fully planted goldfish aquarium. By carefully selecting the best aquatic plants for goldfish tanks, it is absolutely possible. Let us explain.
Select goldfish proof plants
It might sound obvious but by carefully choosing plants that have the correct root systems, it allows you to position your plants in a way that prevents them from being uprooted and destroyed, effectively making them goldfish proof. Even fancy goldfish, despite their cute appearance, can be guilty of a rampage. No plant is goldfish proof without our help.
A Rhizome plant is a group of plants that share a common trait which relates to their root systems. Species such as Anubias plants and java Fern both have rhizomes. Both species can (and should always) be attached to either a rock or wood structure by superglue or fishing line. The rhizome is part of the root system and is easily identified as the thick green roots. These should never be planted into substrate. By attaching to the hardscape above the substrate, they will eventually grow along the surface using their rhizome to hold them. A helpful feature of these plants is their ability to grow in relatively low light environments.
Floating plants are another group of plants that can be helpful in a goldfish tank. While there is a variety of different species of floating plants, some of these are tiny plants, making them the perfect snack for a hungry goldfish. Duckweed is one that springs to mind. Often loathed by fishkeepers and a very fast growing plant, it will be eaten every day and never disappear from a goldfish aquarium. Other species are larger such as water lettuce which is much larger. Also a fast growing plant, the water lettuce produces long roots that they use for soaking up nutrients to help them grow. Due to this, they are a very good natural method of reducing the chance of algae by removing excess nutrients produced by the fish poop. For aquariums with high light levels, the floating plant 'Frogbit' can be a nice addition. Similar to water lettice, they produce long roots.
Onion plant - a strange name and no we are not suggesting you add an onion to your aquarium. The onion plant is also known as Crinum calamistratum is a beautiful plant and depending on the flow, can make an excellent background plant. They get the nickname onion plant thanks to their bulb and the fact it produces long green leaves which do look a little similar to an onion. The long leaves are crinkled and difficult to eat, which make them great plants for goldfish setups. Maybe the name puts goldfish off them?
Java moss - Although golfish do nibble on this species, if kept correctly, it will grow fast enough to remain healthy and attractive enough. Java moss is a great beginner plant and is welcomed in most fish tanks. You can either let your Java moss remain free and floating around the bottom, or to give it more of a chance, we recommend attaching it to some wood or stones using mess and fishing line. Eventually, the moss will grow over and along the surface giving you a nice and natural appearance.
Cryptocoryne - Although grown planted in the substrate (making them more susceptible to damage from your goldfish) Goldfish are not known for eating their leaves. With low maintenance requirments they are one of the best plants to use to create bushy displays.
But what about the layout?
Deciding the layout of aquarium plants is personally my favourite element to any aquascape. Creativity runs wild and it is pretty exciting right? However, in goldfish tanks things are always a little different and this stage of the setup is no different. Here it really helps to research a little more about the plants you decide to use. Aquarium plants don't all grow in the same way.
While the plants listed above are generally the best plants for goldfish setups, we must position the plants for goldfish too. What we mean by this is to take into account the behaviour of your goldfish and their needs before deciding on a layout for your goldfish plants. As you know, your goldfish are boisterous, require a lot of space and produce a lot of waste. This needs to be catered for at all times, otherwise your nice planted goldfish tanks will become impossible to clean effectively.
A good starting point it to learn the way your plants will grow. Some species do grow horizontally and vertically while others tend to grow straight up. This knowledge can help future proof your layout providing you with a great looking and practical goldfish tanks for as long as you wish to enjoy your creation.
Let me explain further. Most of the plants listed above are regraded as a slow growing plant but with their individual growth characteristics, some do better in different areas of your aquarium.
Low light tropical plants such as Java fern, Cryptocoryne and Anubias plants are better placed around the middle due to their overall height capacity and bushy appearances. The Onion plant grows very tall and has long narrow leaves which float beautifully around in the water current. This is a hardy plant that works very well when used as a background plant. It also does well in medium to low light environments.
Most successful planted goldfish tanks are designed in a layout that offers aquatic plants around the edge and back of the aquarium. This gives a fantastic backdrop and still gives the goldfish lots of space for swimming and feeding time. Additionally, maintaining an open spaced front and central makes tank maintenance much more accessible.
So, if you have always wanted to combine aquascaping and goldfish in the one aquarium, we hope the above information will be helpful and encourage you to try it. We do have to stress however, that even with the best of research and attention, there are no 100% fish proof aquarium plants and an aquarium plant may be off the menu for one group of goldfish but the same plants in another goldfish tank may not have the same success. Always monitor your fish and if they take a liking to one of your plants, you can do something about it quickly and try alternatives.
