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.

Are there controlled chronic nitrate, ammonia or nitrite exposure studies in Neocaridina?
A restricted official thesis abstract identifies one chronic total-ammonia comparison in N. denticulata, but unavailable full methods prevent validation of its reported maximum acceptable concentration as a care threshold. No controlled chronic nitrate-only or chronic nitrite experiment was located. Both gaps remain open.
Boundary: This is a dated search record, not proof that no unlocated study exists.
Reviewed 2026-08-12. Result order is textual relevance, not quality, certainty, severity or importance.
Which dissolved-oxygen histories change Neocaridina survival, behaviour, growth or reproduction?
A direct HIF-1alpha embryo knockdown study adds a molecular cleavage result but assigned no oxygen treatment and measured no dissolved oxygen. No controlled dissolved-oxygen treatment series establishing survival, growth or reproduction limits was located. The gap remains open.
Boundary: This is a dated search record, not proof that no unlocated study exists.

Which common hobby treatments are both effective against confirmed targets and safe for Neocaridina?
A direct pilot abstract narrows the boundary for mebendazole and albendazole, but its incomplete dose, one-vessel-per-group design and three-day survival endpoint do not validate a treatment protocol. No controlled efficacy-and-host-safety trial for the named common hobby salt, fenbendazole, praziquantel or peroxide treatments was located. The gap remains open.
Boundary: This is a dated search record, not proof that no unlocated study exists.

Do direct transport studies validate a package combination or an acclimation rate for Neocaridina?
The package-evidence boundary is refined because two direct transport experiments were located. Neither tests the house package or any drip rate, duration or receiving-water formula, so both operational questions remain open.
Boundary: This is a dated search record, not proof that no unlocated study exists.

Does an assigned aquarium comparison establish a Neocaridina filter type, flow rate or turnover rule?
The gap is refined with a quantified field association. No assigned aquarium filter or turnover comparison was located, so no universal hardware or flow rule follows.
Boundary: This is a dated search record, not proof that no unlocated study exists.

Do direct experiments establish combined GH, KH, pH and conductivity optima for Neocaridina?
The occurrence boundary is broader, but no replicated factorial water-parameter optimum study was located. Field ranges and culture values remain contexts rather than targets.
Boundary: This is a dated search record, not proof that no unlocated study exists.

Do assigned light spectrum, intensity or photoperiod comparisons establish an aquarium lighting regime for Neocaridina?
The open thesis adds direct intact-animal location counts and a rotating-lamp phase, but its apparatus and analysis cannot establish preference, welfare or a home lighting regime. Molecular studies show that eyestalk pathways participate in short light responses and may connect with molt physiology. No reviewed source establishes an aquarium spectrum, intensity or photoperiod, so the gap remains open.

Which direct leaf-litter studies separate preference, consumption, decomposition, water effects and long-term shrimp outcomes?
One direct cattail-decomposition lead completed method review, while the direct leaf-choice study still needs complete methods. The microcosm supports faster litter breakdown with direct shrimp access under its tested conditions, but mass loss is not measured intake and zero reported mortality is not dietary adequacy. No replicated home-like leaf comparison links an identified treatment to water safety, complete nutrition, growth, reproduction or disease outcomes.

Does a direct feeding study establish one complete diet, live feed, ration or nutrient target for a Neocaridina colony?
Direct feeding studies show that diet treatment can change growth, survival, colour and reproductive endpoints, but no reviewed source defines one complete food, live-feed requirement, pellet count or nutrient target across the full colony life cycle. The adequacy gap remains open.
Boundary: This is a dated search record, not proof that no unlocated study exists.

Do controlled pedigrees report F1, F2 and backcross ratios for named aquarium colour lines?
The new crustacyanin study adds another functional molecular candidate, but its public record does not expose the complete units or report controlled named-line pedigrees. No study reporting complete F1, F2 and backcross phenotype denominators was located, so the inheritance gap remains open.

Do named fish comparisons measure both adult Neocaridina retention and juvenile recruitment?
No named-fish trial with a shrimp-only control and adult plus juvenile colony denominators was located. Coexistence claims remain unvalidated.

Has a replicated known-hatch Neocaridina cohort been followed through individual deaths in home-like aquaria?
The review now includes an open known-age-cohort thesis that rules out two simple molecular age markers under its protocols. It does not supply a lifespan distribution because no animal was followed to death and the approximate 13-month value was cited from another source. The lifespan gap remains open.

Do multigeneration complete-system experiments establish stable home-aquarium carrying capacity?
The evidence base now distinguishes short grow-out density, field density and unreplicated multigeneration observation. No complete-system carrying-capacity experiment was located.

Which direct Neocaridina microplastic studies measure individual growth, reproduction or survival under home-like histories?
A third fully reviewed direct study adds particle-ingestion and short egestion observations in N. palmata without measuring chronic harm. The 2025 combined cadmium study remains a candidate until its methods can be verified, and the home-like growth and fecundity gap remains open.
