"A tank can hold a fixed number of shrimp per gallon"
Use the complete answer. A verdict without its boundary and next action can become another myth.
What is supported
density can affect outcomes under defined systems and feeding histories.
What is not established
tank volume alone reveals oxygen, grazing surface, waste-processing capacity, maintenance limit or sustainable reproduction.
What to do next
begin with a supportable group, measure system outcomes and set an operation-specific intervention point. Use the stocking guide.
Exact evidence trace
This is the selected claim-level trace, not every source used by the broader guide. Roles describe how each record is used here; they are not quality grades.
Evidence records
- direct support Density and gender segregation effects in the culture of the caridean ornamental red cherry shrimp Neocaridina davidi Bouvier, 1904 (Caridea: Atyidae): Directly compares defined juvenile densities under one culture design.
- limitation context Breeding and life cycle of the ornamental freshwater shrimp Neocaridina davidi in a biofilm-based culture system: One biofilm-based multigeneration system does not establish a universal per-gallon capacity.
Named open questions
- What determines a stable operating capacity in a multigeneration home aquarium? A 90-day juvenile density study, field density and an unreplicated three-generation observation cannot be multiplied into a planted-tank maximum.
Inspect the broader guide evidence dossier for all records, authorities, gaps, searches and changes connected to the practical guide.
