One of the most enjoyable aspects of setting up an aquarium is decorating it. It’s a chance to create a unique underwater landscape for your fish and other aquatic creatures. The big question for many aquarists, whether they’re beginners or seasoned veterans, is whether to choose natural or artificial decorations.
Both have advantages and disadvantages, and the choice ultimately depends on personal preference, maintenance willingness, and the specific needs of the aquarium inhabitants.
Natural Aquarium Decorations
Natural decorations include driftwood, rocks, live plants, and sand. They offer a slice of the natural environment within the confines of glass walls.
Pros
Aesthetic Appeal
There’s no denying the beauty of a well-planted aquarium with natural elements. It can mimic the look of a natural habitat, providing a stunning visual display and a comforting environment for fish.
Environmental Benefits
Live plants contribute to the nitrogen cycle, helping to filter the water naturally. They absorb carbon dioxide and nitrates and produce oxygen, which is beneficial for the fish.
Fish Health and Behavior
Many fish species thrive in an environment that resembles their natural habitat. Natural decorations can provide hiding spots and reduce stress for the fish.
Cons
Maintenance
Natural decorations can require more upkeep. Wood can decay, and live plants need pruning and care.
Water Quality
Some natural materials, like certain rocks, can alter the water parameters, like pH and hardness, which need to be monitored closely.
Limited Variety
Depending on where you live, there might be a limited selection of natural decorations available.
Popular Natural Aquarium Decorations
Here are some popular natural aquarium decorations that can help you bring a piece of the underwater world into your home.
Driftwood
Driftwood is a highly sought-after natural decoration for its unique shapes and the rustic charm it adds to an aquarium. It serves as an anchor for live plants and a hiding place for fish. Before adding driftwood to your tank, it’s essential to ensure it’s aquarium-safe and free from harmful chemicals or pests.
Live Plants
Live plants are not just decorations; they play a crucial role in your aquarium’s ecosystem. They provide oxygen, help maintain water quality, and offer shelter to your fish. Popular choices include Anubias, Java Fern, and Amazon Sword, which are known for their hardiness and low maintenance requirements.
Rocks and Stones
Natural stones and pebbles can create a beautiful, textured landscape in your aquarium. They also offer hiding spots for fish and surfaces for beneficial bacteria to colonise. When selecting rocks, it’s important to choose types that won’t alter the water’s pH, such as slate or river rocks.
Coral
While unsuitable for freshwater tanks, coral is a popular decoration in saltwater aquariums. It adds a splash of colour and complexity to the environment. Ensure any coral added is sustainably sourced and suitable for your tank’s inhabitants.
Sand
A natural sand substrate can give your aquarium a beach-like feel and is preferred by certain burrowing fish. It’s available in various grain sizes and colours to match the aesthetic of your tank.
Aquarium-Safe Wood
Other types of aquarium-safe wood, like Mopani or Malaysian wood, can be used in addition to driftwood. They offer a different texture and appearance, providing more options for aquascaping.
Shells and Fossils
Shells and fossils can add a historical aspect to your aquarium, but they should be used sparingly as they can affect water hardness and pH levels. Always ensure they are clean and free from contaminants before adding them to your tank.
Artificial Aquarium Decorations
Artificial decorations are man-made, ranging from realistic-looking plants and rocks to whimsical castles and treasure chests.
Pros
Durability
They don’t degrade over time and can last for years without needing replacement.
Variety
There’s a wide range of colours and styles available, allowing for a high degree of customisation.
Low Maintenance
Artificial decorations don’t require the care that live plants do and won’t affect water chemistry.
Cons
Aesthetic
While some artificial decorations are quite realistic, they can still look fake and may not provide the same natural feel as real plants and wood.
Biological Function
Artificial plants don’t contribute to the nitrogen cycle or provide oxygen for the fish.
Safety
Some cheaply made decorations can harm fish if they have sharp edges or toxic materials.
Popular Artificial Aquarium Decorations
Here’s a list of popular artificial aquarium decorations that can add colour, life, and whimsy to your aquatic display.
Artificial Plants
Artificial plants are a staple in many aquariums. They come in various shapes, sizes, and colours and can closely mimic their natural counterparts. They’re easy to clean, don’t require light or nutrients, and won’t decay over time. Some popular artificial plants include PVC grasses, silk plants, and those with ceramic bases for easy anchoring.
Resin Ornaments
Resin ornaments can range from realistic rock formations and wood replicas to whimsical figures and themed sets. They are durable, non-toxic, and can add a lot of character to your tank. Popular themes include sunken ships, treasure chests, and cartoon characters.
Ceramic Decorations
Ceramic decorations are another favourite among aquarium enthusiasts. They can be shaped into caves, tunnels, and terraces, providing excellent hiding spots and play areas for fish. They are also available in various colours and styles to suit any tank theme.
Artificial Rocks and Caves
Artificial rock aquarium decor and caves give fish a place to hide and explore without the risk of altering the water chemistry. They can be made from non-toxic plastic or resin and come in many realistic designs. Some even have built-in air pumps to create bubbles for added visual effects.
Silicone Corals and Anemones
Silicone corals and anemones are a fantastic option for saltwater tank owners or those who want to mimic one. These saltwater aquarium decorations offer the vibrant colours and intricate designs of natural corals without the need for specific lighting or water conditions. They’re also soft and flexible, which is safer for the fish.
Themed Decoration Sets
Themed decoration sets can transport your aquarium to another world. From Greek Roman aquarium decor and pirate adventures to fantasy landscapes, these sets often come with multiple pieces to create a cohesive look. They’re great for kids or anyone who loves storytelling through their tank’s design.
Glow-in-the-Dark Decorations
Glow-in-the-dark decorations can add a fun and mysterious element to your aquarium. These decorations absorb light during the day and glow softly at night, creating a mesmerising effect. They’re especially popular in children’s rooms or as a nightlight feature.
Making the Right Choice
The decision between natural and artificial aquarium decorations is personal and should be made based on what’s best for you and your aquatic pets.
Consider the time and effort you’re willing to invest in maintenance, the look you want to achieve, and the well-being of your aquarium inhabitants.
Natural decorations might be the way to go if you enjoy aquascaping and have the time for maintenance.
If you prefer a set-it-and-forget-it approach, artificial decorations could be more suitable.
For those who want the best of both worlds, a combination of natural and artificial decorations can be used. This way, you can enjoy the benefits of live plants while incorporating fun and unique artificial elements requiring less upkeep.
Remember, your fish’s well-being should always come first. Whatever type of decoration you choose, make sure it’s safe and appropriate for your aquarium’s inhabitants.
