What to Look for in Aquarium Decorations
1. Safety First
- Ensure decorations are labeled “aquarium safe” or “non-toxic”
- No sharp edges or loose pieces that can harm fish or damage fins
- Boil or rinse all new decorations before placing them in the tank
2. Fish Behavior Compatibility
- Betta fish love resting spots near the surface
- Bottom dwellers like corydoras and loaches need caves or soft spaces
- Territorial fish benefit from visual barriers to reduce aggression
3. Water Chemistry Impact
- Driftwood can lower pH—great for softwater fish
- Rocks like limestone raise hardness—ideal for African cichlids
- Neutral items like slate or lava rock are safe for most setups
4. Size and Placement
- Don’t overcrowd—leave room for swimming space
- Anchor tall decorations securely to avoid tipping
- Ensure decorations don’t block filter flow or heater circulation
