Ornaments must be safe and not release harmful chemicals. Some materials can change water quality or harm fish. Choose non-toxic, aquarium-safe items.
| Material | Safety Level | Notes |
| Plastic | Safe | Check for aquarium grade |

| Metal | Unsafe | Rusts and poisons water |
| Wood | Safe if treated | Use aquarium-safe driftwood only |
Color And Texture Choices

- Trim plants regularly to prevent overgrowth
Coral And Shell Accents
Coral pieces add a natural ocean look to freshwater tanks. They also help balance tank minerals.
Shells offer hiding places and interesting textures. They can raise water hardness, helping some fish.

Placement Tips For Small Tanks
Decorating a small aquarium can be fun but tricky. You need to use space well to keep it lively and neat.
Choosing and placing ornaments right helps fish feel safe. It also makes your tank look beautiful.
Maximizing Visual Depth
Use different sizes and heights of ornaments to create depth. Place taller pieces at the back and smaller ones in front.
Layer ornaments to make the tank look bigger. This gives a natural and rich view to your small space.
- Put tall plants or rocks in the back corners
- Place medium items near the middle

Creating Focal Points
Pick one or two special ornaments to be the center of attention. This draws the eye and adds interest.
