Buying Guide

Match decor to tank size and bioload

Choose ornaments and live shrimp appropriate for your aquarium’s gallon capacity and filter capacity to avoid overcrowding and water-quality stress

Prioritize shrimp provenance and compatibility

Select neocaridina or caridina varieties with clear sourcing and compatible water-parameter needs to prevent aggression and breeding issues

Select aquarium-safe materials

Use non-toxic resin or ceramic ornaments and avoid painted items that can leach; branded decorations often disclose materials and safety testing

Consider hiding places and territorial cues

Thematic ornaments that provide caves, crevices, or surfaces help shrimp and small fish feel secure and reduce stress-related behavior

Factor in maintenance and cleaning

Choose decorations with accessible surfaces for algae scrubbing and avoid intricate pieces that trap detritus; live shrimp can aid cleaning but still need regular tank maintenance
