What To Put In Fish Tank For Decoration – Crafting A Thriving Aquatic
So, you’ve got a beautiful aquarium, and it’s time to bring it to life! But what to put in fish tank for decoration that’s not only visually appealing but also safe and beneficial for your aquatic inhabitants? It’s a question many hobbyists ponder, and honestly, it’s where the real magic happens.
Choosing the right decorations transforms a simple glass box into a miniature ecosystem. It provides hiding places, reduces stress, and enhances the natural beauty of your fish and shrimp. We’ll dive deep into the best options, from natural elements to curated pieces, ensuring your tank is a haven of both aesthetics and well-being.
The Foundation: Substrate Choices for Your Aquarium Landscape
The very base of your aquarium, the substrate, plays a crucial role in both decoration and the health of your tank. It’s more than just pretty gravel; it influences water parameters and provides a home for beneficial bacteria.
Gravel: The Classic Choice
Standard aquarium gravel is a popular and affordable option. It comes in a vast array of colors and sizes, allowing for endless creative possibilities.

- Grain Size: Finer gravel is better for burrowing fish like Corydoras catfish. Larger pebbles can be used for a more dramatic look but might be harder for smaller fish to navigate.
Sand: A Naturalistic Touch
Aquarium sand offers a more naturalistic and often preferred substrate for many species. It creates a soft bed and can be particularly beneficial for bottom-dwellers.
- Play Sand: Washed play sand is a budget-friendly option, but ensure it’s free of additives. Thorough rinsing is essential.
- Specialty Aquarium Sands: Brands offer specific sands for planted tanks or marine setups, often with added nutrients or beneficial properties.
- Benefits: Sand can provide a substrate for beneficial bacteria and is ideal for fish that like to sift through their environment.
Specialty Substrates for Planted Tanks
If you’re dreaming of a lush, planted aquarium, specialized substrates are a must. These are designed to provide nutrients for aquatic plants.
- Aquasoil: These nutrient-rich, porous substrates are formulated to promote plant growth and often help regulate pH.
- Inert Substrates with Fertilizer: Some aquarists use a layer of nutrient-rich substrate topped with sand or gravel.
Crucial Tip: Always rinse your substrate thoroughly before adding it to the tank. This removes dust and debris, preventing cloudy water.
Bringing Nature In: Rocks and Wood for Authentic Aquascaping
Natural elements are fantastic for creating a realistic and stimulating environment for your fish and shrimp. They offer hiding spots and can even influence water chemistry.
Rocks: Stability and Structure
Rocks can add incredible structure and visual interest to your aquarium. However, not all rocks are aquarium-safe.
-
Safe Options:
- Slate: Flat, dark, and stable, great for creating ledges or caves.
- Lava Rock: Porous and lightweight, offering excellent surface area for beneficial bacteria.
- Dragon Stone (Ohko Stone): Known for its unique, pitted texture and earthy colors.
- Seiryu Stone: Popular for its dramatic, sharp features and striking veins.
-
Rocks to Avoid:
- Limestone and other calcium-rich rocks: These can leech minerals and raise the pH and hardness of your water, which can be detrimental to some fish species.
- Rocks with sharp, jagged edges: These can injure your fish.
- Testing Rocks: Before adding any new rock, perform a simple vinegar test. If it fizzes, it contains calcium and should be avoided.
Driftwood and Aquarium Wood: Organic Beauty
Driftwood adds a natural, aged look to any aquarium. It provides hiding places and can even release tannins, which mimic a blackwater environment favored by some fish.
-
Types of Aquarium Wood:
- Mopani Wood: Dense, dark, and often with intricate shapes.
- Spiderwood: Known for its slender, branching structure, creating a “spiderweb” effect.
- Cholla Wood: A hollow wood that’s excellent for shrimp and small fish to graze on.

- Java Fern: Similar to Anubias, it’s robust and can be attached to hardscape. Avoid burying its rhizome.
- Pothos: Yes, the common houseplant! Its roots can be submerged in the aquarium, and it draws nitrates from the water. Just keep the leaves out.
- Marimo Moss Balls: These spherical algae are unique and require very little care.
Mid-Level Plants for More Lush Tanks
Once you’re comfortable, explore plants that add more texture and color.
- Cryptocoryne: Come in various shapes and sizes, with beautiful leaf patterns. They benefit from a nutrient-rich substrate.
- Amazon Swords: Larger plants with broad leaves, perfect for the background of a medium to large tank.
- Water Wisteria: A fast-growing stem plant that’s great for filling out space and for fish fry to hide in.
Advanced Plants for Planted Tank Enthusiasts
For those seeking a vibrant aquascape, these plants offer a challenge and reward.
- Rotala Species: Many Rotala varieties offer stunning red and pink hues with proper lighting and CO2.
- Ludwigia Species: Similar to Rotala, these stem plants can create breathtaking color gradients.
- Dwarf Hairgrass: A delicate carpeting plant that creates a lush, grassy carpet effect.
Planting Tip: Always rinse new plants thoroughly to remove any pesticides or hitchhiking pests. When planting stem plants, use tweezers for precision. For Anubias and Java Fern, attach them to wood or rocks rather than burying their rhizomes in the substrate.
Artificial Decorations: Safe & Budget-Friendly Options
While natural elements are fantastic, artificial decorations can also be a safe and appealing choice, especially for beginners or those on a budget. The key is to ensure they are aquarium-safe.
Resin Ornaments and Sculptures
These are incredibly popular, offering a wide range of designs from shipwrecks and castles to artificial plants and caves.
- Material Matters: Look for ornaments specifically made for aquariums. They are usually crafted from inert resins or plastics that won’t leach harmful chemicals.
- Smooth Edges: Ensure any openings or edges are smooth to prevent fish from getting injured.
- Avoid Sharp Objects: Steer clear of anything with sharp points or fragile parts that could break off.
Artificial Plants
High-quality artificial plants can add color and movement without the maintenance of live plants.
- Silk Plants: Softer and more realistic than plastic, silk plants sway gently in the current and are less likely to tear delicate fins.
- Plastic Plants: Durable and easy to clean, but can sometimes have a rigid appearance. Ensure they are made from non-toxic plastic.
- Cleaning: Regularly remove artificial plants and scrub them with an aquarium brush to prevent algae buildup.
Substrate Enhancements
Some artificial decorations are designed to complement your substrate.
