"Neocaridina clean the tank"
Use the complete answer. A verdict without its boundary and next action can become another myth.
What is supported
Neocaridina graze algae, microbes, detrital material and food-associated surfaces.
What is not established
grazing guarantees control of a visible growth, replaces maintenance or exports the consumed nutrients from the aquarium.
What to do next
identify the material and correct light, inputs or maintenance while treating shrimp as animals, not equipment. Use the grazing 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 Consumer species richness and nutrients interact in determining producer diversity: Directly measured grazing-related outcomes under its stated comparison.
- direct support Omnivorous shrimp Neocaridina denticulata sinensis enhances the growth of submerged macrophyte Vallisneria denseserrulata: Separates local periphyton and plant outcomes from water-column nutrient and chlorophyll outcomes.
- limitation context Promotive performance of shrimp Neocaridina denticulata on Typha angustifolia leaf litter decomposition: Separates litter breakdown and fecal effects from proven intake or whole-tank cleaning.
Named open questions
- Which identified and conditioned leaf litters improve Neocaridina outcomes in home-like systems? One abstract-level N. davidi study reports leaf choices and normalized consumption. A fully reviewed N. denticulata microcosm study separates direct shrimp contact from fecal contact on one cattail preparation and measures litter breakdown, enzymes and water chemistry, but not intake, dietary adequacy or long-term shrimp outcomes. The taxa, litter species and endpoints differ, and neither record establishes disease benefit or a replacement interval.
