The Ultimate Aquarium Ornament Buying Guide
Adding decorations to your fish tank makes it look amazing. Ornaments provide hiding spots for your fish too. Choosing the right ones keeps your aquarium healthy and beautiful. This guide helps you pick the best decorations for your underwater world.
Key Features to Look For
When shopping for aquarium ornaments, several features matter. These features ensure safety and visual appeal.
Safety First: Non-Toxic Materials
- Material Safety: Always check that the ornament is labeled “aquarium safe.” Toxic paints or cheap plastics can leach harmful chemicals into the water.
- Smooth Edges: Run your finger (carefully!) over the ornament. Sharp edges can easily tear delicate fish fins. Good ornaments have smooth, rounded finishes.
Size and Scale
- Tank Size: A huge shipwreck looks great in a 100-gallon tank but will overwhelm a small 10-gallon tank. Match the ornament size to your tank volume.
- Fish Size: Consider your fish. Large, active fish need more swimming space. Small ornaments work best for nano tanks or tanks with many small fish.
Aesthetics and Theme
Think about the look you want. Do you want a natural riverbed, a sunken pirate theme, or a colorful fantasy scene? Choose ornaments that fit your desired theme.
Important Materials Used in Ornaments
The material an ornament is made from directly affects its safety and longevity in the water.
Resin (Polyresin)
Most detailed ornaments are made from polyresin. This material is great because it holds fine details well. High-quality resin is heavy and inert (it won’t react with water). Always ensure the resin is fully cured and painted with fish-safe, non-toxic paint.
Ceramics and Clay
Ceramic pieces, like small pots or natural-looking rocks, are popular. Ensure they are unglazed or glazed specifically for aquariums. Unglazed ceramics can sometimes leach minerals, so research the specific item first.
Natural Materials (Use with Caution)
- Driftwood and Rocks: These bring a very natural look. However, you must prepare them properly. Wood must be soaked until it sinks. Some rocks (like limestone) can change your water chemistry by raising pH and hardness.
- Avoid: Never use painted stones, shells with sharp edges, or wood you find outside unless you boil and treat it thoroughly.
Factors That Improve or Reduce Quality
Quality isn’t just about looks; it’s about durability and safety over time.
Quality Indicators (Improve Quality)
- Weight: Heavy ornaments stay put. Light ornaments often float slightly or get moved easily by powerful filters or digging fish.
- Paint Adhesion: Good quality paint will not chip or fade quickly after weeks underwater. Test the paint by gently scratching it before purchase, if possible.
- No Sharp Seams: Molded plastic or resin items sometimes have rough seams where the two halves meet. Quality manufacturing minimizes these rough spots.
Quality Reducers (Reduce Quality)
- Flimsy Plastic: Thin, cheap plastic can degrade faster in water and may leach plasticizers, which are bad for fish.
- Hollow or Light Structures: These are easily knocked over, potentially trapping smaller fish underneath.
User Experience and Use Cases
Ornaments serve functional roles beyond just looking nice.
Providing Shelter
Fish need places to hide when they feel stressed or are sleeping. Caves, hollow logs, and dense ruins offer security, especially for shy species like plecos or certain cichlids. Make sure any cave has at least two openings so a fish cannot get trapped inside.
Creating Territory
In tanks with multiple fish, ornaments act as visual barriers. These barriers help define territories, reducing aggression between fish.
Tank Maintenance
Consider how easy the ornament is to clean. Highly intricate pieces with many nooks and crannies gather algae quickly. Smooth or large-opening ornaments are much easier to scrub during water changes.
Aquarium Ornament Buying FAQs
Q: How often should I clean my aquarium ornaments?
A: You should clean them every time you do a major water change, usually every two to four weeks. Gently scrub off any visible algae using an aquarium-safe brush or a soft cloth.
Q: Can I use ornaments from my garden or yard?
A: Generally, no. Garden items might have chemical residues, pesticides, or sharp edges. If you must use natural items like rocks or wood, you must boil them thoroughly first to sterilize them.
Q: Will plastic ornaments float?
A: Most plastic ornaments are designed to be heavy enough to sink. However, very cheap or thin plastic items might float initially. If an ornament floats, you can often secure it to the substrate using clear aquarium silicone.
Q: Are brightly colored ornaments safe?
A: Bright colors are safe only if the paint used is certified non-toxic for aquariums. If the color seems applied on the surface and rubs off easily, avoid it. Natural, muted tones are often safer bets.
Q: How do I stop algae from growing on my decorations?
A: Algae growth is normal. You can reduce it by ensuring you do not overfeed your fish and by keeping your light duration to about 8-10 hours per day. Manual scrubbing during water changes removes what grows.
Q: Should I put ornaments in a new tank immediately?
A: Yes, adding ornaments early helps establish the biological filter because surfaces allow beneficial bacteria to colonize. Just make sure the ornament is thoroughly rinsed first.
Q: What is the best way to hide filter tubes or heaters?
A: Use ornaments strategically! Place taller, denser ornaments like plastic plants or rock formations behind or around equipment like heaters or intake tubes to conceal them from view.
Q: Do fish prefer real or artificial plants/decorations?
A: Most fish appreciate decorations that mimic their natural environment. This could mean dark caves (for shy fish) or lots of dense foliage (for active swimmers). The preference depends entirely on the species you keep.
Q: Can ornaments introduce diseases into my established tank?
A: Yes, if you put decorations from another tank directly into yours without quarantine. Always rinse new ornaments thoroughly. If they came from an already established tank, consider soaking them in a mild bleach solution (followed by extensive rinsing) or salt water before adding them.
Q: How much of the tank floor should ornaments cover?
A: Aim for about 30% to 50% coverage. You need enough open swimming space for active fish, but enough structure to provide hiding spots and visual breaks.
