Choosing Safe Materials
Decorations make community tanks look lively and natural. Choosing safe materials is key to protecting all fish.
Unsafe decorations can harm fish by releasing toxins or breaking down in water. Use only safe, tested items.
Non-toxic Decorations
Always select decorations made from non-toxic materials. These keep fish safe and water clean.
- Use natural stones like slate or quartz, which do not release chemicals.
- Avoid decorations painted with unknown or bright paints that may contain lead.
- Choose plastic decorations labeled safe for aquarium use only.
- Driftwood is good if properly cured to remove tannins.
Durability In Water
Durable decorations last long without breaking down in water. This prevents pollution and fish injury.
| Material | Durability | Notes |
| Slate Stone | High | Does not affect water chemistry |
| Plastic | Medium | Use aquarium-safe plastics only |
| Glass | High | Fragile but safe if unbroken |
| Driftwood | Medium | Needs cleaning and curing |
| Painted Wood | Low | Can peel and harm fish |
Avoiding Harmful Chemicals
Check decorations for harmful chemicals that can poison fish or plants.
Follow these tips to avoid harmful chemicals:
- Do not use decorations with unknown paint or coatings.
- Avoid metals that may rust or leach toxins, like copper or lead.
- Rinse new decorations well before adding to the tank.
- Stay away from decorations made from treated wood or plastics not labeled for aquarium use.
Natural Elements
Natural decorations create a healthy and relaxing environment in community tanks. They mimic the fish’s natural habitat and help reduce stress. Using natural elements also supports water quality and fish behavior.
Choose decorations carefully to balance beauty and functionality. Natural materials like wood, plants, and stones offer shelter, hiding spots, and breeding places for many species.
Driftwood And Rocks
Driftwood adds a natural look and releases tannins that soften water. Rocks provide structure and surfaces for algae and bacteria to grow. Both materials create caves and hiding spots.
- Choose untreated, aquarium-safe driftwood to avoid toxins.
- Use smooth rocks to prevent fish injury.
- Arrange wood and stones to create natural caves and arches.
- Clean materials thoroughly before adding them to the tank.
Live Plants
Live plants improve water quality by absorbing nitrates. They also provide shelter and food for fish. Plants like Java fern, Anubias, and Amazon sword thrive in community tanks.

| Anubias | Low to medium | Slow |
| Amazon Sword | Medium to high | Medium |
| Hornwort | Medium to high | Fast |
Substrate Options
Substrate affects plant growth and fish health. Choose substrates that suit your tank’s needs and inhabitants. Sand and gravel are popular choices for community tanks.
Common substrate types include:
- Sand:Soft on fish and good for bottom dwellers.

Using artificial decorations helps keep the tank easy to clean. They do not decay like real plants and last a long time.
