Buying Guide

Match decor to tank size

Choose ornaments scaled to your aquarium dimensions to avoid crowding and to preserve swim space for fish and invertebrates

Prioritize aquarium-safe materials

Look for resin, food-grade plastics, or proven live-invertebrate sources to prevent leaching and water chemistry shifts

Consider biological compatibility

Pick ornaments and shrimp species that suit your water parameters and community—Caridina and Neocaridina have different pH and hardness preferences

Think about maintenance access

Choose pieces that are easy to remove, clean, and reposition to simplify tank maintenance and avoid algae hotspots

Balance aesthetics with hiding spaces

Thematic pieces and castles add style, but ensure enough caves and plants for shy fish and molting shrimp to reduce stress
