Search the complete knowledge library
One deterministic finder reaches practical guidance, tank-side first decisions, bounded definitions, recurring claims, reviewed studies, supporting authorities, named uncertainty, reproducible searches and public corrections. It retrieves existing records and never generates a care answer.
Result type is part of the answer boundary. A guide gives practical direction. A glossary term standardizes wording. An evidence record describes a study. An authority governs a method or external rule. A gap states uncertainty. A search documents method. A change records history. None silently becomes another type.

Temperature results depend on the outcome being measured
The studies can coexist because they used different temperature treatments, durations, life stages and endpoints. A faster process is not automatically a better lifetime outcome, and survival during one protocol does not make every tested temperature equivalent.
Boundary: The corpus does not establish one universal aquarium optimum, a lifetime safe interval or how commercial lines differ across complete life cycles.
Reviewed 2026-08-12. Result order is textual relevance, not quality, certainty, severity or importance.
Grazing on algae is not the same as cleaning an aquarium
The studies measured different compartments and processes. Consumption or disturbance can reduce algae on a surface while recycling material into feces, dissolved nutrients or suspended production. Local removal is not system export.
Boundary: The corpus does not provide a home-aquarium cleaning rate, a stocking rule for algae control or a nutrient budget that transfers across tanks.

Visible colour can change without proving inherited identity
Environmental plasticity and biological pigmentation mechanisms can both be real. A visible phenotype reflects genes, development, environment, measurement and selection history; changing one visible measure does not authenticate ancestry or genetic purity.
Boundary: The corpus cannot map every named trade line to a validated genotype, predict offspring from seller labels or separate all environmental and inherited contributions from a photograph.

A diet result is specific to its formulation and endpoint
The experiments compare different formulations, controls, rations, life stages and outcome windows. A food that changes one pigment measure is not therefore complete, and a reproductive result cannot be assumed for juveniles or every commercial product.
Boundary: The corpus does not establish one complete diet, universal portion, feeding frequency or long-term product ranking across lines and colony conditions.

A biological response is not automatically a care threshold
These endpoints answer different questions. Molecular or biochemical responses can occur without measured mortality, while a short no-death observation does not establish chronic safety. Nominal exposure, water chemistry and taxon verification also affect transferability.
Boundary: The corpus does not establish a universal home-aquarium copper threshold, product-dose rule, antidote or chronic no-effect level for every water chemistry and line.

A published species name is evidence context, not permanent identity
Taxonomic conclusions depend on the specimens, characters, loci, reference material and species concept used. Later reassignment changes how an older result should be scoped; it does not erase the observation or transfer it automatically to N. davidi.
Boundary: The corpus does not resolve every Neocaridina species treatment, authenticate commercial animals from a photograph or make one barcode a universal identity test.
