When planning an aquascape, both form and function must be considered. The appropriate decorations depend significantly on whether you have a freshwater or marine aquarium. Freshwater aquariums typically house tropical fish and live plants, requiring specific substrate, driftwood, and lighting. Marine aquariums contain saltwater fish and invertebrates needing specialized protein skimmers, refugium, and water flow. In both cases, the layout should provide ample swimming room and hiding spots and replicate the natural ecosystem as much as possible.
The goal is to fashion an environment where inhabitants can thrive while crafting an aesthetically pleasing underwater setting. This requires understanding species’ needs and getting creative with materials to build a balanced, beautiful world.
Habitat & Territory
Rocks & Driftwood:
Place rocks and driftwood strategically to create little nooks for fish to hide, breed, and establish personal space. Jagged lava rock, holey river rocks, bogwood, and Manzanita branches offer crevices and overhangs that mimic natural structures. However, avoid sharp edges that could tear delicate fins and scales. Smooth river rocks and sanded, rounded bogwood are safer options.
Live plants generate oxygen, absorb fish waste, filter the water, and define territories with differing heights and densities. Lush green crypts, broad-leafed Amazon swords, vivid red tiger lotus, and feathery hornwort oxygenate while providing hiding spots. Floating plants like frogbit and water sprite shelter betta fish that inhabit warmer surface waters. Tailor plant choices to aquarium temperatures.
Artificial Caves & Tunnels:
Ceramic caves, plastic tunnels, and resin ornaments replicate nooks that creatures would discover in their native habitat. Strategically place these novel shelters and passageways to encourage exploration and enrichment. Just ensure the ornaments have smooth lines and openings large enough for inhabitants to access comfortably. Such structures lend visual excitement while supplementing the other decor.
Gravel & Sand:
Gravel and sand set the foundation and significantly impact the aquascape’s aesthetic. Colored gravel in green, blue, or pink shades creates a vibrant, eye-catching look. Natural tan eco-complete planted aquarium substrate with nutrient-rich clay granules suits planted tanks. For goldfish and koi ponds, more considerable grain smooth pebbles aid waste cleanup. Texture and color choices for substrate depend on the desired environment.
Artificial silk plants, plastic greenery, and colorful aquarium trees add hassle-free embellishments. Unlike live plants, they don’t require special lighting or fertilizers. And they come in blue, purple, and other unnatural hues. Strategically place these fake embellishments to complement live plants and animals.
Aquarium backgrounds create the illusion of depth while concealing unattractive equipment. Black backgrounds make fish colors pop. 3D layered backgrounds have cutouts for plants and decor. Consider photographically printed rainforests and coral reefs for themed aquascapes or other scenic backdrops. Background choice impacts spatial perception and plays a supporting role.
Air Stones & Bubbles:
Air stones and bubble decor infuse water with oxygen while adding visually appealing movement. Bubble wands, bubble curtains, and colorful air stones entertain inhabitants. For planted aquariums mainly, strategic aeration facilitates gas exchange.
Waterfalls & Fountains:
Attaching a powerhead to make a cascading waterfall or installing a decorative fountain establishes a dynamic focal point. The splashing water breaks up surface tension, boosts oxygenation, and replicates natural waterways. However, the relaxing trickle or noisy splash impacts the suitability of certain aquariums.
Strategically placed LED light strips and spotlights highlight focal areas, strengthen plant growth, and allow customizable settings. Blue moonlight LEDs create a serene night glow, while warmer white LEDs support photosynthesis. Mimicking daylight cycles with customizable LEDTimer lighting maintains natural bio-rhythms for aquarium residents.
Live rock forms the biological engine of a saltwater reef tank by housing beneficial bacteria for filtration. Craggy shapes like Tonga branch rock or Fiji live rock leave cracks for coral attachment and fish hiding spots. Slowly acclimate new live rock in quarantine to avoid introducing parasites before incorporating into the display.
Coral Frags & Colonies:
Vibrant Zoanthid colonies, pulsing Xenia soft corals, and plating Acropora corals breathe life into marine aquascapes with color, movement, and biodiversity. Match easier soft corals with more demanding SPS corals based on factors like lighting needs and growth rates. Consider compatibility, feeding behaviors, and space requirements when designing the coral layout.
Artificial Reef Structures:
Ceramic, resin, and plastic reef rock blend seamlessly with live rock while offering additional surface area. Coral frag plugs, acrylic discs, and coral propagation plugs inserted into PVC pipe racks provide attachment points for dividing corals. Spongy, porous landscape cement blends or aragonite sand beds encourage microfaunal settlement. Such artificial structures supplement natural decor.
Sand & Substrate:
Saltwater tanks require specialized substrates to maintain high pH. Popular options include:
Coarse sugar-fine oolite sand that allows detritus passage.
Porous aragonite sand promotes bacterial growth.
Live sand seeded with beneficial microfaunas.
Tailor substrate to inhabitant needs, like crushed coral for calcium-dependent stony corals.
Transformative backdrops lend saltwater aquariums majestic realism and depth. 3D layered coral reef backgrounds get multidimensional with raised coral shapes. Holographic and shimmer film backgrounds refract light like sunbeams penetrating the ocean. Themed shipwreck or ruin imprints excite the imagination. Deciduous: Consider angled side panels to prevent claustrophobia from panoramic backgrounds. Thoughtfully chosen backdrops transport viewers to fantastical underwater vistas.
Powerheads & Wavemakers:
Replicating the surge of ocean currents with powerheads and wavemakers increases oxygenation while ensuring all tank inhabitants receive adequate, regular water flow. Consider flow needs, positioning intake/output strategically to prevent dead spots and detritus buildup. Diminutive soft corals prefer lower flow than robust stony corals.
Bubble curtains infuse playful motion and supplemental aeration as bubbles rise, catching light. Position acrylic anti-splash guards to prevent water splashing and noise disruption. Site decorative bubble towers away from delicate coral colonies vulnerable to surge damage. While visually appealing, excessive surface agitation outgasses critical carbon dioxide.
LED lighting allows customization catering to a reef’s diverse coral occupants and aquatic plants. Blue LEDs conjure deep sea intrigue, while intense 14,000K white LEDs fuel photosynthesis. Some corals flourish under purple and green wavelengths. Recreating ebb and glow intensity mimics natural light variation. Mix LED color spectrums and place spotlights to highlight focal areas for stellar effects.
When selecting aquascapes, carefully factor in inhabiting species’ temperature preferences to provide suitable habitats. Coldwater species like goldfish and koi thrive in unheated tanks with smooth gravel substrates and hardy plants like Anarchis and Vallisneria. Warmwater betta splendens and guppies favor heated waters around 25°C matched with fine gravel and broad-leafed plants.
Beyond temperature, assess decoration materials to ensure stability, lack of toxicity, and ease of maintenance when planning aquascapes. Strategically place decor to prevent dead zones from lacking circulation. Fragile structures or live plants need trimming, while bulky wood/rocks require moving for cleaning. Optimally design captivating underwater havens catering to resident needs for healthy, thriving ecosystems.
