The lifecycle of Neocaridina denticulata and N. palmata in aquariums

What was studied

Study shape: Thirty market-sourced animals per labelled species, 15 male and 15 female, first shared one aquarium per species. Fifteen ovigerous females per species were later described as moving to individual aquaria for egg and hatch observations, after which healthy offspring were reared and measured through a reported maturity sequence. Only descriptive statistics were stated.

Experimental unit: One initial aquarium per labelled species, so species and tank were confounded; the number, size and independence of the later female and offspring aquaria were not reported, and individual offspring tracking was not described

Endpoints: adult and post-hatching total length, egg length and width, attached egg count per female, reported time to life-stage labels, temperature, pH, dissolved oxygen, nitrate, ammonia.

Claim boundary

What it can support: Under the reported culture history, the market-sourced groups produced attached eggs and direct-developing shrimp-like young. Fifteen females under each label supplied reported egg-count ranges of 21 to 60 for N. denticulata and 21 to 58 for N. palmata, and photographed post-hatching young measured about 3.3 mm at 24 hours.

What it cannot support: Species identity rested on market sourcing, colour and photographs without a diagnostic key or molecular confirmation. With one initial aquarium per label, species and tank were confounded, preventing an independent species comparison. Female isolation, offspring allocation, starting hatch denominators, survival, losses and repeated-animal tracking were not reported. The stated June 14 to August 10 breeding interval does not reconcile with 75-day and 80-day observations. Tables place ranges in columns labelled Means while also giving separate standard deviations, figures and axes are inconsistently numbered or labelled, and no inferential model is reported. Temperature and pH varied within the same systems rather than being assigned, so plots cannot establish 27 C as an optimum or any pH effect. The water methods, analyte bases and nitrogen interpretation are incomplete, and nitrite named in the abstract is not reported in the tables. Calling the direct-developing young larvae and describing a planktonic phase conflict with the better-resolved N. davidi developmental literature. The source cannot establish a universal 15-day incubation, 75-day maturity calendar, water-quality threshold, species difference or cultivation optimum.

Correction impact

If this source boundary changes, these are the known downstream consumers. The list distinguishes scientific re-review from generated parity and historical follow-up.

Editorial review required (13)

This curated wording or synthesis must be reconsidered when the source boundary changes. A passing generator test cannot decide the new scientific meaning.

Historical record needs follow-up decision (2)

Do not silently rewrite history. Decide whether the prior change record remains accurate and publish a new correction or scope note when needed.

• Has a replicated known-hatch Neocaridina cohort been followed through individual deaths in home-like aquaria? Dated literature search
  The dated search used this exact source as a candidate (included: The lifecycle of Neocaridina denticulata and N. palmata in aquariums). Preserve the search history and decide whether a revised or additional search is required.
• Two aquarium reports did not create a universal maturity clock Historical research change
  The historical change cites this source. Preserve the old decision and decide whether a new public correction is required.
