Buying Guide

Match decor to tank inhabitants

Choose ornaments and live shrimp appropriate for freshwater setups and compatible species — for example, Neocaridina and Caridina shrimp strains are common choices for planted community tanks

Prefer aquarium-safe materials

Select ornaments from brands that specify non-toxic, aquarium-safe plastics or resins to avoid altering water chemistry or harming fish and invertebrates

Consider shrimp strain and care needs

Different shrimp like Amano, Neocaridina, and Caridina have varying water parameter tolerances and social behaviors; pick strains that match your tank's pH, hardness, and temperature

Check stocking numbers and group size

Live-shrimp listings commonly specify pack counts; plan group sizes to provide social interaction without overloading biological filtration

Balance aesthetic and functional features

Thematic ornaments (e.g., character figures) add visual interest but should also include hiding spots and smooth surfaces to protect delicate shrimp and fish
